Cadillac ATS Transmission Fluid & Filter Change | Shudder Be Gone

[@franzm77]

Absolutely great video. A local shop wanted $500. I completed it within 2 hours thanks to this video. The CTS has no shudder and shifts smooth as butter. I used the fluid extractor and pulled all the old transmission fluid out before removing the pan. Not one drop was spilled. the fluid he uses in the video is the correct one. Mobile 1 has another fluid but with a black label. Dont get that one.Make sure you get the blue label. Mine still had the factory filter in it so it hasn't been changed in 100k. There is a date code on the GM filters. the 4 ramps gave me enough clearance to roll around on a creeper. I used a body panel rivet remover to get the fill plug out. You can also use 90 degree long neck pliers.

DUDE YOU ARE A LIFESAVER. Just changed the transmission filter & fluid after my car kept jerking & when putting into drive wouldn’t move unless i tapped the gas. Bought that hose from harbor freight & you saved me thousands of dollars. Rides like new. Belle tire wanted 6k for a new trans & told me it was shot. 2013 Cadillac ATS 2.0T AWD. Hardest thing was fitting my fat hand to put the tube into the fill hole lol. Thanks again brother, much appreciated! Also you helped my change my rear diff fluid. Ended up have to replace the rear diff dude to leaking & running out of gear oil.

[@sstressfl]

Fluid and filter at minimum for sure 👍 you want to make sure you have proper fluid flow. An old blocked filter can cause low line pressure.

[@drd6539]

Thanks for doing this! The ATS gets neglected on forums, and there aren't many DIYs, especially for transmission fluid changes. You're just about as meticulous as I am when you get under the car, make 4 passes around the oil pan when tightening, etc. Glad to know I'm not the only one.

When I changed my front and rear differential fluid at 62,000, I was surprised at how milky and thin-looking it was. So I ended up doing it again after 1000 miles or so.

I flip cars as a hobby so this was my last project before the COVID Pandemic hit. I bought the XTS dirt cheap at 121,000 miles. The shuddering issue around the 122,000 mile mark.

[@VelleyIndustrial]

Just did this service. Yeah, the 4 ramps trick works but sketchy. You can drain some fluid via the plug but you will spill some anyway. There is a replaceable lip seal that seals to top of the filter funnel. I did mine at 88k and it was cleaner than in this video. I did have the fluid flushed at 50k. If you have AWD the front axle drive shaft is really in the way. To get the plug back in I used a plastic 90 deg fork too that is made for removing snap in panel fasteners. That got the plug back in in 20 seconds after wrestling with it for over 20 minutes. Total job time was 2 1/4 hours.

Augie Spano that’s great!! As you can see, it’s necessary service. Glad you’re getting it done 👍

[@MS-es9hm]

recommend always making sure the fill plug comes out okay before draining in case you have a problem, same for differentials. Also with the change you did you didn't get the dirty fluid in the torque converter so there can be 30-50 more there depending on the setup. Thats why dealers offer a flush and a pan/filter change like you did. I have them do both so i get the bennies of both new fluid and a new filter. But great job on the video!

[@sstressfl]

Good tips! There’s an older service bulletin online where they change the fluid 3x this way to get the tc fluid as much as possible. That was my plan, to do it again soon, but once I took it in to the dealer for a different problem, I asked them to diagnose the shudder. And they did. The previous dealership told me it was not bad enough yet and I didn’t press. Which is why I changed my own fluid. And as you can see, it seriously needed to be done. My car is at a new dealership and they have been magnificently helpful. 👍 ThAnk you for your feedback 🙏

Flushing the tranny cause more damage to your Valve body and solenoids. Best way itS to drop the pan and drain, Change Tranny oil filter , Don’t use DEXRON VI that stuff is junk and what makes your tranny fail! Use Mobil 1 LV ATF HP. Then wait 2 weeks and do the same drain and fill and tranny oil filter change and thats how you get all that Old Dexron VI out .

The metal shavings are normal in a pan drop and fluid change. The magnet is there to hold captive the debris from freely circulating through the transmission. A good schedule for this maintenance is every 60,000 miles. Copper nickel antiseize on the pan bolt threads is going to help future you get the bolts out without trouble

[@sstressfl]

The ats 6 speed calls for a 35k fluid and filter change. And the volume of shavings and clutch material is not normal when shuddering due to contamination starts at 20k. It’s excessive. My 100k transmission fluid change in my Dodge Grand Caravan looked about the same which was expected at 100k.

[@MarcsRandomVids]

In case you have to do this to another car, here is an easier (for me) method. I saw you have air compressors. Use the large bottle of fluid. Use 2 3/8 or smaller plastic fishtank type tube. Make 2 exact tube diameter holes in the fluid container cap and stick one tube down to the bottom. Put the other end of that tube into the transmission. Put the other tube into the cap about an inch. Use low air pressure and put air on that tube end. It will force all the trans fluid into the transmission.

[@junior281991]

All that stuff you pulled off the magnet and from the bottom of the pan, that stuff is normal. Its very fine metal and clutch material which happens with use of any automatic transmission. What you dont want is actual chunks or metal shavings that look like they have been scraped off but, that very fine stuff will always be there.

[@sstressfl]

At 100k yes. Not at 20k when the shudder started. The filter was saturated. Low Line pressure. None of this is normal.

[@strongfp]

Metal sludge is normal in a transmission, it's sort of healthy to be honest. It means your transmission teeth have worn together. One of the worst things to do is to flush the transmission, a simple change of filter and fluid is all you need. After I did my second change on my ATS it was much clearer. I plan to change mine every other year, because I know their transmissions are very complicated and sort of known to have issues.

[@sstressfl]

You speak truth!! :) I do know why you're saying not to flush, but on a newer transmission like this one that is filled with excessive metal and clutch sludge that causes shuddering, a flush is the actual solution dictated by GM (albeit temporary until it fills up with contaminant again). Doing it manually helps tremendously though. Especially if you do it multiple times like you did. An older transmission that has been neglected can start shifting horribly after a flush... the process strips away sludge that is keeping it functioning. And I agree with you... I think an annual change on this transmission is required for long life. Thanks for your feedback and enjoy the ATS!

[@duanecarr6712]

Safety first love it

[@tankertuff278]

Recommend complete transmission oil flush at a mechanic shop. You do a drop pan/ filter but the tranny itself will have oil in it that you can’t drain with just swapping the oil.

[@sstressfl]

Like I said in the video, it might require multiple pan drops to get rid of the shudder. GM says 3x is usually required. A flush is a great way to get it done if you have access to a trusted mechanic. Besides, the 8 speed will need a flush every 30k miles to keep it from shuddering. The 6 speed will usually only require one in its lifetime. But also this was diagnostic for me. It proved that contamination was the root cause of the shudder.

[@gohan9638]

You should change your transmission valve body. I hade the same issue I changed the fluid, filter and valve body because I seen my fluid like your if not with more metal shaving sludge so I thought my solenoid was clogged or the valve body it self because the fluid expansion when hot/warm and having sluggish old fluid can cause those little passages to get clogged or partially clogged. So long story short if you have problems with your transmission when it's hot or warmed up I think you should definitely change those 3 things before more damage

[@sstressfl]

Thats great advice! The dealer ended up flushing it. It's fine now! But shy of a power flush, the valve body could have stuff stuck in it.

[@davidterceira7451]

Hey Mike, always tighten in a X pattern. If you don’t know where to start, always in middle and outward. Nice job!

Sorry it didnt seem obvious. Thats how I tightened it in the first wave. The round about was to make sure I didnt miss any.

[@tomquinn607]

Most mechanics will advise a pan drop and filter change just like Michael did. They advise against a full flush to avoid slippage.

[@sstressfl]

Thanks Tom! In my life, it has always been a standard service (at different mileage with different vehicles) to drop the pan and change the filter. A flush was a rare service, usually tied to transmissions that had serious problems/contamination. And I did read that a flush can help clean an old transmission "too well" and cause shifting issues. But with these 6 and 8 speed transmissions from GM, especially well under 100k miles, the flush might be the only fix for the shudder... or a 2x or 3x home-fluid change.

[@paulslovacek449]

I am doing mine now. I drained fluid, cleaned, installed new filter and put pan back on. Six quarts came out and I am filling back up now. How do I know how many quarts go back in? I saw another video and the guy said to remove the drain plug and fill till it comes out there. Any help would be great. Thanks

[@recrdholdr]

FYI What you saw in the oil pan is mainly clutch material and the amount you had was very minimal.

[@sstressfl]

You think so? I've never seen that much material and especially not in a car with 40,000 miles. It's excessive. Steel. Aluminum. And clutch material. I've gone 100,000 miles in cars and not seen that kind of corruption. I'm about to change the transmission fluid in my 2015 Grand Caravan with 100k on the odometer. It'll be interesting to compare.

[@sstressfl]

Nice vids by the way. I grew up at the track :)

[@sstressfl]

@@zacharyball8009 i guess I misunderstood. I agree it looks very contaminated. And by normal you mean normal for this specific transmission then yes.... at 40k miles this 6 speed looks like other transmissions do at 100+k miles. I just dropped the pan on my 2015 Dodge Grand Caravan at 100k and it looked similar if not healthier. And the van’s transmission is smooth as silk and has never shuddered. And the Dodge has a recommended fluid change at 120,000 miles or 60,000 with heavy towing. The 6l45 is indeed a very weak and/or poorly designed/low quality transmission.

My ATS had the shuttering issue, known issue with 8 speed transmission. Dealership did fix with new fluid, different weight, and a new computer flash. GM totally knows there is something wrong with this transmission. Car hasn't felt the same since they did this, feels like a less torque is making it to the wheels. I think they are just limping me along until the warrant is over. Dealership said in the early days they were replacing the torque converter but this is the new fix now. It does shift better and now shutter, but sometime still doesn't act right. Just wondering what the long term out come will be with this car.

But when it comes to noises in the rear suspension, won't touch it. Shuttering, just change the fluid and re-program computer. When I complained that it doesn't shift and drive the same, you get excuses that it's in your head. Now I've got the noise coming from the front driver side suspension.

One problem. When tightening the bolts start in the middle and do a cross pattern. Center bolt on one side then center on other side. Then back to opposite side. Then back to opposite side and rotating in a cross cross pattern. Tighten to 8ft. lbs. First pass 4 lbs 2nd pass to 8ft. lbs

[@sstressfl]

lol only because you understand 😂 uhhg how did fluid changes get so scary expensive? The pan drop and filter change should give you a huge improvement.

I agree it looks almost normal, but I’ve changed a lot of trans fluid. This stuff is way too much for a car that started its problems at 20k. Even more than I’ve seen at 100k.

hello there i have a Cadillac ATS-V and i have been suffering from this shudder since i bought the car, so this oil you talked about in the video is it suitable for ATS-V?? Note: i drove the car for 73,000 kilometres without changing the transmission oil once, as the dealer said there is no need.

I did not! I read that 3 fluid changes are almost equal to a flush. I had planned to do 3... at least try 2, but then my car ended up at the dealership and they took care of it. And thanks for the feedback! :)

[@danielemenard5971]

Great video, thanks. I have a Cadillac ATS 2014 AWD. My question is: does my transmission needs to be hot, my car has been on stands for a couple of days.Do i need to go to the gears ? How do i know how much oil is in the gears ect...In your video you took out six quarts of oil and put it 6. How can I tell if I have the correct amount of oil? Is it possible I’m missing a bit of oil to begin with? Thank you Alex.

[@sstressfl]

Does not need to be hot! Do not go thru the gears. Drop the pan and change the oil. I read that others used 6 qts when they replaced their trans oil and so I measured to make sure that 6 qts was correct. I drained 6 qts and it’s as others have said. I added 6 qts. There is a process to replace all of the fluid but it requires much more fluid and the ability to pump it thru the trans while it is running. The best at home job I can do is to put in a new filter, new fluid. It will make a huge difference. Perfect? No. But you can try to change it again in the future and the new filter should have caught much of the remaining contaminants. The option is to pay the dealership to flush it for you. I hope that helps! Let me know how it goes for you!

[@JC-qu4um]

Hello ! I currently have a ats 2015. I was thinking of changing the transmission fluid due to the fact that when breaking it begins to pull back but only does it every once in a while. Would it possibly be due it hadn’t had a change in the transmission fluid ?

[@sstressfl]

The transmission fluid interval I think is 35k on this car. It sure doesn't hurt to keep it fresh and clean! Especially that filter... once it gets filled with metal and clutch material, it gets blocked and lowers line pressure in the transmission. Its also possible you have a transmission issue (I cant be sure) but my attitude is do what you can do cheap and easy first! And, its hard to diagnose until you have fresh fluid and a clean filter.

Thank you very much for the vid Micheal. It helps guide me through the same process with my 2014 ats that has worsening transmission shudder at 65k. The shuddering is now gone. However, I now have grinding noise coming from the tranny at 1st and 2nd gear regardless of mode (auto or manual). It happens all the time at cold start but much less often after driving for about 30’. What do you think is the problem? I used 6 qt of the atf just like you did. I spilled i littlr during pumping but the spill is very small.

[@sstressfl]

Awesome that the shudder is gone! But grinding is not good. Assuming it could have improper fluid level. The transmission is very sensitive to proper level. Were you able to measure the amount of fluid that came out? There is a way to verify the level using the fluid level bolt on the pan. I hope it's just improper level, but I hate that there is noise, it's possible you have some wear damage internally. A buddy of mine is having his 2013 ATS 6 speed auto completely rebuilt right now due to internal damage and his has been maintained by the dealership :( I pray that's not your situation. But start with verifying proper level first! Let me know what you discover!

[@quangvu4093]

@@sstressfl turned out the fluid was low ☹️I had assumed that my garage was level and thus, putting the car on 4 jack stands would identical to your case. So I only put in 6 quarts just like you did without actually measuring how much I took out. Turned out the garage has a freaking slope (the level tool confirmed it). I jacked up the front two axles up via the middle jack point (with backup jack stands on the sides) to make sure the car is level and do the transmission fluid level check at 122F (with an IR gun); no fluid came out of the drain hole. It took 1/2 more quart to be at proper fluid level. Apparently, tilting the car to the front caused 1/2 more quart to come out. At the end, the car now shifts smoothly on all gears. Hopefully my stupid mistake didn’t cause too much damage after about 100 miles of driving 😑

[@charliemik7284]

Bought a 2014 ATS4 Premium 3.6 in August, 2024 with 100,000 miles on the odometer. It had a loud rear differential noise and the deal included a new rear differential assembly. No parts in western Canada, waited 4 weeks for delivery and then was informed the delivery company lost it in shipping. Supplier could reorder but would have the same delivery time. I insisted the dealer look elsewhere and they agreed. They found one in Toronto and it was shipped by ground next day. 2 weeks passed and I called the dealer for an update last week and was advised the parts arrived, the car was brought back into the shop, and when the mechanic went to install, it was discovered that the diff was the wrong one. Waiting now for callback on arrival date of new parts. The point to all this is…. While I have been waiting for the car that I bought 2 months ago, made 3 payments on, been registered and insured, I have not received the car yet, and I have been scouring the net for possible issues, upgrades, tips, and tweaks. In doing so, I came across your transmission flush. I thought about why the rear diff was toast in an AWD car and came to 3 possible conclusions: 1 - The oil leaked out of a seal or the vent cap, thereby starving the diff of lubrication, 2 - The car had been towed, front wheels up, pretty much trashing the rear diff, or 3 - The car had a shitty diff at birth. I surmised if it was the most likely culprit, the previous first owner had neglected to properly check and service the fluid levels beyond the engine oil, and that has me wondering about the transmission fluid. Rather than wait until it is crying for help, I will use your excellent video to perform the same services to the transmission. I will go one step further, though (especially if the fluid is the color of yours), and will drive it several hundred miles, then I will perform the same procedure again. This is because there is a significant amount of that dirty old fluid held within the torque converter that instantly mixed with your new fluid. I know the fluid now in the torque converter will also be contaminated, but to a much lesser degree than the first change. Thanks for your patience and effort in making this video. I hope it’s not too late to prevent any damage to my transmission, but all I can do is offer it TLC to sooth the neglect, if that was the reason for the diff failure. Cheers! 🥂

[@sstressfl]

I met a guy on the cadillac forum who said his wife's ATS went thru 4 brand new diffs before they found a good one. The rear diffs on the awd model are simply poor quality. Some have upgrade the Camaro M6 differential. Requires new axles. But its solid compared to the Caddy one. And yes! If youre doing a pan drop you need to do it multiple times (GM says 3x before its good) to clean out all the ick. I had planned to do this, but the dealer ended up doing it for me. After a flush the 6 speed auto in my 2015 was flawless. I think you'll find the transmission is a-ok once you get the fluid clean. Its mostly low line pressure from the clogged filter.

[@charmik741]

Thanks for sharing. I thought I might be overthinking the initial fluid change with only 2 changes. My 2005 VW Passat V6 5 speed AT AWD has the same procedure for the AT service and no dipstick. Timing belt change and transmission R&R are listed 12 hours each, when a non-VW mechanic can do either in 7-8 hours. Non-criminal robbery!

[@sstressfl]

@charliemikolcevic741 oh that’s terrible. My brother n law was a Ford mechanic for a little while. He said things like brakes booked at 3 hours but he would finish in 45-60 mins. Still billed at 3 hours and his pay was billed at 3 hours. They are highly motivated to go fast! Usually amounts to sloppy work. Broken fasteners. Missing bolts. Improper torque settings etc etc. You know how it goes 👍 My best to you on your project. I’m sure it’ll go well 🙏

[@charmik741]

I apprenticed as an auto mechanic for a couple of years after high school back in 71 to 73. I could do most good and proper tuneups on almost any American car in under an hour. The dealer manuals allowed 3-4 hours. My employer was very honest with his customers and he usually billed for my time rounded to the closest hour. Unfortunately, I was not a beneficiary of flat rate billing, but if I was, I could have done up to 8 tuneups in a day and got paid for 25-32 hours on my check. Back then, mechanics were not paid well compared to other trades, like plumbing, electrical, refrigeration, hydraulics, engineering and welding. But you had to have some working knowledge of all of those skills to properly perform your job well. Most mechanics today are more like parts persons with tools; they read codes and change parts until the offending code disappears. Often, many good parts are changed before the root cause of the problem is discovered. Do they remove the other parts and reinstall the old, but still good part? No. Why? Not because they are not good, but because they also get a percentage of the parts cost for the repair. Some dealerships say they can’t refund electrical parts once installed so you have to pay for them. Always ask for your old parts to be returned to you for all repairs, unless they are required as a core. In that case, ask for the mechanic to show you what failed and why. If they have to answer to their actions, they are less likely to replace good parts, or to bill for parts that were not actually replaced. The service side of dealerships is just as shady as the sales side. 😢

Hey man i have an ats 16 and it has about 28k mileage and it shudders should I change the transmission fluid and what kind of fluid does it take.

[@daniell.2730]

Should you change out the fluid even if the car has more than a 100,000 miles? I was told not to switch the liquid because it might just cause more problems so I’m debating trying out the Lucas transmission fix instead.

[@sstressfl]

Historically transmissions that have not been serviced get all worn and gummed up inside. New fluid has a way of cleaning it and washing away the gunk that was keeping things sealed. So sometimes after changing fluid on an old transmission.... it gets worse because the new fluid washes and cleans all the old gunky stuff out. So its a gamble. I usually go ahead and change the fluid and filter. If it makes things better then YAY! If not... then boooo, I'm paying for repairs. But if you want to try the Lucas stuff, feel free. You'll need to remove some fluid to make room for it. But I suspect you probably need a new filter inside that thing. Its gonna be clogged and causing low line pressure. Whatever you decide, if the transmission is giving you grief, you have to do something or it'll eventually leave you stranded somewhere. Praying for a good outcome!!

[@baderaltami6737]

My Cadillac is close to 70,000 miles, can I change the gear oil for the first time after this mileage without any problem?

[@sstressfl]

I would!! It’s not like a transmission. It’s chunky metal inside with 3 seals keeping the fluid from dripping out. Also make sure the vent on the top of the differential is clear and breathing free. They get plugged easily. If it’s an AWD you can use Amsoil SVG fluid or the GM equivalent. If it’s a RWD use the GM fluid spec’d for that specific differential. 👍

[@melo1986]

Great video man. I had a question. Does this service require a non slip additive to the oil?

[@sstressfl]

No not at all. The new Mobile HP fluid was designed with a little extra friction modifer to help with the probems in the 8 speed. Its Dexron 6 with a boost :) But many people use the regular GM fluid (AC Delco) with no problems. The important thing is to change it and get a new filter in their. If you have a serious shudder, multiple fluid changes (3) might be needed or a professional flush. Hope that helps!

[@NFINTHEHOUSE]

This is such a great video, I have a 2013 ATS and it’s shuddering really hard. I’m not a car guy at all and a couple places I’ve talked to have said that changing the transmission fluid will actually damage it. Have you ever heard of that??

[@sstressfl]

Yes I have heard that many times. An older high-mileage transmission can develop a bunch of tarnish and gunk inside which actually helps it keep working. Once you put fresh fluid in the trans, it "washes" the transmission and cleans some of the built up varnish and breaks up the gunk which can make the tired old transmission start to slip. However if I was faced with a shudder, I'd change the fluid and filter in a heart beat. I can't stand the shudder. But that's just me. To me its worth the risk. Plus the new trans fluid is synthetic. It doesn't gunk up like the old stuff. It's not my car. But if it was, I would risk it and chase after the fix and start with a fluid and filter change. Just be aware, that you might need to do it 2 or 3 times total to rid your car of all the old fluid. If it doesnt work and it starts to slip real bad, you'll need repairs or a new/used trans. You have to make that judgement call. But again, to me, I'd gamble on the fluid. And spend the money on the repair if I had to.

[@sstressfl]

@@xCaRnRAGEx Hey that's great! It should feel better with a pan drop change but that torque converter holds about 50% of the fluid so multiple fluid changes/filters are usually required to get it close to perfect.

[@robbypro3370]

Small metal shavings is norm on the magnet 🧲

[@sstressfl]

The issue is that this started at 20k miles and yet this transmission looks like one that has 100k miles. Fluid was so saturated with metal and clutch material that it caused low line pressure due to clogged filter and the contaminated fluid aided in slip.

[@HoldMyBeverage]

Silly question, if you remove that fluid check bolt. could you put the pump hose in there and pump the fluid out? About to do this myself and trying to figure out a way to do it that doesn't end with me dumping this on my face.

[@sstressfl]

lol... the face splash is a very real risk! But the reason they do transmissions this way (at least I always thought so) is because you need to replace the filter. And the only way to do that is to drop the pan. Sadly that fluid check bolt won't help you to empty it. I have heard of people adding drain plugs to their pans! But that won't save you for this fluid change. Wear safety glasses! :)

Hey bro great video, so by dropping the transmission oil pan you replaced about half of the total ATF capacity for this transmission, if you wanted to change all of the transmission fluid on this ATS, what approach would you take?

[@sstressfl]

You could take it to a dealer and let 'em pump it through ;) Or remove the overflow bolt and pump more fluid into the mix to dilute it yourself - but its driving better than it ever has since I bought it at 17k. Here's how I see it... It's NOT the fluid so much as it is the incredible amount of metal shavings. It needs a new filter asap. It needs the magnet to be cleaned off, it needs the pan to be wiped clean. Just like the magnet, the old filter was completely maxed out. I suspect the shavings in the bottom of the pan get sucked up while driving, press up against the saturated filter, restrict proper fluid flow, then fall back down into the pan when you stop driving. Shuddering, poor shifting, all of it is due to the shavings. Once you have the new filter installed it will grab the remaining metal shavings. You could change it again (as some ATS owners do) and replace the filter again. And the old fluid? Its synthetic! Its capable of many more miles, but it's the corruption of the fluid, not the viscosity of the fluid that needs to be fixed.

[@maximusdpsimus2278]

@@sstressfl This is exactly it. Your video helped me do my 2014 ATS and I had the exact same findings. TONS of metal shavings in the pan and the old transmission filter was fully gunked up.

My ATS has ~55k and would shudder really bad, but just did the 6quart drain/refill with a new filter and it's a complete day and night difference. No shudder at all after long trips/highway driving and the car is much smoother in it's shifting. My next plan is to do the rear-diff drain/refill as I think this would help also.

Typically the fix for 6 speed shudder is trans fluid and filter flush. Sometimes (but more rarely) the torque converter needs to be changed. The manufacturer recommends fluid and filter change at 45k miles. After I changed mine it made a huge difference but not 100% perfect. Eventually the dealer used a proper flush to replace 100% of the fluid and that is what finally fixed it. I hope that helps.

If any place shy's away from a flush its because they will refuse responsibility if ur car stops shifting. They will tell you they warned you.. but in reality what they dont tell you.. is a flush could possibly ( break loose material caked inside the transmission ) and it will no longer catch gears.. now what the service advisor should've told u is a drain & fill with a replace of gasket & filter isnt the same thing. Thats what u seen in this video. Drain & fill with new filter and gasket.. idk why places dont explain this too customers. Oh plus dealers usually want proof the atf was changed on time usually before claiming responsibility for destroying ur car.. lmao

Hello so I have this problem when I’m pulling out of a parking spot the car shutters so if I was to do this it should at least help it or even fix it thanks

[@sstressfl]

Do you get shudder any other time? Like when you're going up a hill in high gear, or lightly accelerating at around 4-50mph? If so yes, prolly transmission. If not, it could be a loose engine or trans mount, or a fuel delivery issue...

[@Zutiac]

@@sstressfl I do not it’s only when I start the car sometimes and start to pull out of my driveway or like a parking spot I pull out and it feels and sounds like the cars wheels are slipping I have a 2013 XTS and I read some forums and a lot of people that drive the 2013 cts xts and ats all say around 120k miles their cars starts to do it and some say it could be a torque converter what do you think it could be besides what you replayed to me. Thank you

[@sstressfl]

@@Zutiac could be low line pressure in the trans due to a clogged filter. I usually start by making sure fluid is fresh and filter is clean. Make sure car is in proper tune then go from there. At some point you gotta dig in 👍

[@Zutiac]

@@sstressfl yup thank you so much

[@AssassinsxNiGHT]

Great video but since you have a AWD unit you probably should have change the transfer case fluid as well

[@sstressfl]

This was experimental and it proved worthy! But right after this, the car has been in and out of the dealer for warranty work ever since. More than 100+ days and counting :/ I have the transfer case and front diff fluid, and Winter has finally ended but I haven't had the car..... and it's still at the dealer.

[@AssassinsxNiGHT]

@@sstressfl I bought my 2018 ATS a half year ago and I have a sound on the front driver side of the car that sounds like a grimy wheel bearing took it in they said it was a broken wheel hub still makes the noise to this day I feel your pain with the ATS it’s a shame because it seems like the car is built really well but many people online seem to have countless problems with this car

[@sstressfl]

@@AssassinsxNiGHT It is by far the most incredible fun driving car I have ever owned and at the same time.... the worst car I have ever owned. Sorry you're experiencing that noise. It completely ruins what would otherwise be an amazing driving experience.

[@tjsworld2338]

Where did you get the fluid? I can’t find any locally. I found it on amazon for 6quarts at 44 dollars.do you think that 6 quarts is enough? And the gasket is reusable? Thanks

[@sstressfl]

Amazon is good! Great price too 👍 6 will do it 💯 Gasket is completely reusable. It’s actually meant to be reused. Don’t forget the filter!

[@tjsworld2338]

Michael Byrne lol yeah I already picked up the filter today from the dealership. I should have just picked up the fluid as well but thought I could find Mobil 1 locally because I wanted to do it tomorrow. Guess I’ll have to order it. Thanks for your help

[@rrayw757]

I've got a 2014 ATS 3.6 with about 40k and I recently started noticing the shudder. Dealer would charge $400 so I'm going with your method. Thanks for the information. BTW sometimes to get my A/C to blow cold I have to tap the temp control all the way to HI and back to LO. I cannot find any info on this and the dealership is at a loss but they did change out expansion tube / valve and condenser which helped the overall problem of not cooling at all. any ideas....thanks again RRW

[@sstressfl]

I’m guessing the blend door actuator is malfunctioning. It’s behind your glove box. I would remove the glove box and take a look to see if it’s working right. Hope you can fix it!

Do you happen to have a link for that pump you're using?

Just added a link in the description below the video 👍 Thanks for asking! The link might help some others too 🙏

[@braezysnipez2073]

how do i check the oil level after i pump the new oil in?

[@sstressfl]

I measured what I drained out of mine and put back the same amount. But if you need to check the level, this should help! www.cadillacforums.com/threads/changing-transmission-fluid-2014-ats-2-0l.1094535/

[@sstressfl]

Yes mine is the same! You can also use the standard spec dexos vi gm fluid. Good results with that too. And cheaper!

[@DennnnnnnY]
