[@ItsDrillz]

@@chrisfix I clicked on this video SPECIFICALLY to make sure you explained how flushing can cause loss of function in cases with no prior transmission service. You nailed it. Awesome job.

[@guseks8413]

@@ItsDrillz So maybe you can answer a question from me if you know things about transmission. I thought my car shifted abit weird (I have a sealed transmission) so when I had it at my usual shop for service they told me I should get it flushed and they refered me to another shop that had a machine for it, so I did. At the time my car had done about 180200 miles(I know quite abit) and serviced according to the book, and since it is a sealed transmission I don't know if the previous owner had ever changed fluid on it before. Anyway to the problem: Right after they flushed the transmission the car shifted kind of weird when it was warm, say if you drive 10-20 miles highway and then go into city traffic it shifts hard and when accelerating on highway it is like it shifts 1,5 times per shift if that makes sense, first a shift and then another small jump that changes like 200rpm. After like 100 miles of driving it stopped doing that and it shifted super smooth and it was great, but now after another 8000 miles it has started again. When the car is cold it shifts nice and crisp but still smooth. Could it help to change oil again or is it just done and ready for the scrap? Or maybe there is something else one could do? Could they have put the wrong kind of fluid in? Thanks for answers :)

[@ItsDrillz]

@@guseks8413 I don't think there is a way to for me to know the full extent of the condition of the transmission over the internet. As you stated, we also cannot know the previous owner's treatment of it either. This is where I wrote a big long explanation with the possible causes of the issue but I decided instead to just sum it up with recommending you take it back to the shop that did the flush and have them diagnose it. It is much too complicated for me to make a recommendation of a fix without being able to see or test the car. If you'd like the full explanation, reply to this comment and I'd be happy to write it for you but the short answer is to take it to the place that's had the car because they would know more about your car or at least be able to test it and verify the issue. I worked mainly with GM products in the past and don't recommend flushes on cars over 120,000 miles unless they are already losing function. It is too much of a liability to flush it and end up with a slipping transmission.

Sounds like a dumb question and maybe is, I’ve just never noticed it before but it could’ve been doing it the entire time. Just wanted to know if I should get something checked out.

His computer said it would be 1.5 hours of labour but he said that's not right it will be no where near 1.5 hours to do both. took him less that 45 mins and only charged me for less than a hours labour. Saved me $80. He has not seen my Civic yet but i might get him to change the brakes soon.

[@HawaiiFoodAndFun]

I usually do all the work for my family. Maybe there's someone you can ask.

[@sidgar1]

Best way to find a good, trustworthy, and honest mechanic is by word of mouth. If you have a friend or someone you know who can vouch for them, that's usually a really good start. Also look at Google or Yelp reviews. Don't let 1 star reviews turn you completely off, though. Sometimes people who don't know anything about cars will complain about prices, or they went in for one service and declined another service the mechanic told them they really needed, but they declined, and then they broke down, and then they blamed the mechanic who tried to warn them. My rule of thumb is to weigh the number of 5 star reviews against the 1 stars. But referrals plus these reviews should land you at a really reliable and honest place more often than not.

[@kingspartacus2407]

I work in the service industry and I would love to show my customers this video.

All the cruze models 2009 & 2010 had a problem in the AT gearbox and all thos gears had failed and changed by the retailer at our expenses (unless you raise your voice and then you may get 50-75% discount)!!. It is a shame since the gear fails after 30000-50000 km and a brand new car will need to change the transmission completely (which I did) after only 3-4 years of modest service. Anyway we were told by the retailer that same problem may occur again in the newly replaced transmission and that there is always the same risk of failure transmission just after the oil change. So, yes sometimes just doing the normal timed oil change will bust you transmission, ask 2009 k 2010 Korean made chevy Cruze owners

[@Mijanboy]

@@joshymcdaniel9233 There is a simple answer to that. If the manufacturer claims that the filling in the automatic transmission is for life, you do not need to change the oil. The transmission should last 150,000 km = that's the guarantee of new Mazda cars. 6 years or 150,000 km. This means that the lifetime of the Mazda is 150,000 km. If the transmission dies at 160,000 km, everything is OK = it's only your problem. If you plan to keep the car longer, you must service it accordingly. My Mercedes had 1,603,xxx km when it was taken out of service due to massive body corrosion.

Bashirsz Darz late reply, but if I were to guess I'd say that either some kind of grease is thickening in the cold, or a small amount of water is getting in there and freezing, making it so it takes more force than the actuator can apply... But I can't be at all sure about that

[@olddavid4]

BD- Do not forget that cold weather affects battery strength, which may contribute to your problem. I also weatherize my car locks by getting a graphite oil and applying it to my keys and run them in and out as well as turn many times to be sure it has gotten to all mechanisms. Also, apply some type of lubricant to the catches of your doors, hood, and trunk.

[@joeschoe4477]

I've been tormented about this for months. Thank you! A drain and fill is the next logical step.

[@Tacticaldesertdweller]

I have worked in a transmission shop for 30 years. if you service your transmission every 12 to 15 thousand miles with a simple pan drop service it should last indefinite. Transmissions rely very strongly on the viscosity of the fluid, and when it gets old and wears out is when you have problems. as for flushing cars that have not had regular maintenance. ATF is the highest detergent fluid there is at 180 degrees. It tends to break years of sediment that has trapped behind the clutches, behind the apply pistons, and in the crevices of the valve bodies loose all at once. this is why people say that a flesh is not a good idea. if you had regular maintenance on your vehicle you won't need a flush. when the flush machines came out we bought one. I've seen cars drive in the shop. get a full system flush. and then not want to move back out. the new fluid broke all the debris loose that fast. our $7,000 machine now sets in the corner collecting dust. chrisfix gave the right advice when he said regular maintenance. I've always recommended that you change it once a year right before your busy time. just the simple pan drop service and change the filter. that will keep your viscosity of the fluid up to good level.

[@frbird51]

When it comes to transmissions, whether automatic or manual, only use the fluid / lubricant that it calls for in your owner's manual.

There's also an in-line filter that is easy to change, but hard to get to because of the all the objects in the way. I have heard too many horror stories about Honda autos so do not want to be a victim when it can be avoided cheaply.

[@jshepard152]

I'm just happy to know there's someone in the world who changes their ATF at 12k miles. If I do mine at 75k I feel like a rock star.

[@kevinbarry3066]

When I bought my 2nd car( I was 19) the trans fluid had a slight dark tinge so I went to get a fluid change, ( here come the fun part I'm standing there when he pulls the filter and sets it on the drill press and pick up some shavings from the drill and puts in on the filter( guess he forgot I was standing behind him). He brings the filter and me to the manager and says"ooohh this trans is shot look at the metal in the filter" The manager looks at me and says" let me work up a number for a trans rebuild"." I said OK can I use your phone"? "who are you gonna call"? The police I saw your man take those slivers off the bench press and put them on the filter and I'm gonna have you arrested for fraud". Mgr "let's wait a second and talk this out". "sure change fluid put new filter for free" Mgr went OK' got it for free and STILL reported him to Motor Vehicle Service of the City and State of N.Y. Went by a few weeks later and place was boarded up.

Many years ago we took our vehicle in for a fluid and filter change. The guy at the shop said it wouldn't help and showed me the little filings in the pan. He wanted me to commit to a rebuild. I couldn't afford it at the time so they just put the old transmission fluid back in and sent me on my way. He said I would be back in a month for a rebuild. My dad convinced me to change the fluid and filter. Man was I ticked off when I pulled the pan off of that transmission and found that they had torn the screen off of the filter and just put the old fluid back in. I didn't know how to do a flush at the time so I just changed the fluid and filter. WOW!!!! All of my shift problems cleared up and the car ran great for as long as we had it. So I always, ALWAYS recommend doing a fluid and filter change a least or a (flush is best in my opinion.) You don't have to pay the big bucks for a flush either. You can just do the fluid and filter change first. Then before you start the engine take off the return hose FROM the transmission cooler going back TO the transmission and direct it to your drain pan. Then start the engine. Your new fluid will push the old fluid out all the way through the system including but not limited to your torque converter and trans cooler. When the fluid coming out of the return hose is clean your system has been almost completely flushed. ALMOST. I don't know what percentage didn't get changed but this is pretty thorough. I do NOT believe the shop in my situation put any metal filings in the pan. There are frequently vary small fibers and filings in the bottom of an oil pan. I am CERTAIN they tore off the screen from the filter! My filter was just a fine mesh screen. I would have turned them in but I figured it would be just my word against theirs. It just makes me wonder how many people they conned and how long it went on.

[@1960JCRAY]

My father worked for a large law enforcement agency for many years. Back in the 70’s the agency did a sting operation where they took an old beater car around to various transmission shops for so called repair. Much of the internal parts of the transmission were marked for identification purposes and to determine if parts had been replaced. The car was driven to the shops with a relatively easy fix, just a vacuum hose was disconnected. Of the 13 shops checked, 8 would be transmission shops committed fraud by selling the undercover officer an alleged transmission rebuild. To this day I still don’t trust transmission shops.

[@jeffreystroman2811]

JC RAY yup, sounds about right, sadly transmission shops are more often than not going to scam the customer because so little is understood. And the ones who are trustworthy gain local legend status. Outside Philly it was Pats transmission, good guys.

[@paulmorphy6638]

It isn't restricted to trans shops. Many regular mechanics and oil change shops also take advantage of the common driver. They either upsell on work not needed or just outright cheat by not doing what they charge for. People's unfamiliarity with how their cars work is what gives dishonest workmen the upper hand.

[@1960JCRAY]

Paul Morphy I completely agree with you. Three years ago I took my 4 wheel drive truck in for some work at a transmission shop. The transfer case on the truck had been completely rebuilt less than 1000 miles earlier. The owner of the transmission shop called me to inform that the fluid inside the case was black in color as if it had never been changed in 200k miles. Knowing the case had just been rebuilt, I called his bluff. Advised him it was just rebuilt and asked him if he believed the rebuild case was failing. The shop owner did a complete 180 and said the fluid didn’t look that bad. Yes, always trying to rip you off.

[@paulmorphy6638]

Always loosen the fill hole first. Otherwise you can loosen the drain plug and drain the fluid...... And not be able to fill it if the fill bolt won’t come out

Letting a novice see what the benefits and consequences of changing and/or flushing versus waiting too long are outstanding. I like the physical breakdown and visual aid of seeing all the valves and channels of a transmission as well as the fact the torque converter hold a lot of fluid.

[@80sfordguy]

Chris, this is the most informative video I’ve seem on transmission service wether that be changing or flushing the fluid. As a transmission builder I’m asked these same questions pretty much daily and most of the time the customer is still apprehensive about doing a flush or fluid change. I’ve told customers similarly as you stated basically, if the fluid is darker than a maroon color that I only recommend a fluid change. I advise them to do service as the OEM stated in their owners manual or damage will occur. Your explanation and demonstrations of the fluids, and hard parts is remarkably accurate and commendable as a KZbin DIY’er and your channel is always a good recommendation for every individual DIY’er. If the customers fluid is pink (very rare) unless recently flushed or red then I recommend a fluid flush although not using a trans flush machine. After 20yrs of diagnosing, rebuilding and maintaining thousands of transmissions for my customers. I’ve always flushed the tranny’s via the trans cooler return line at the trans method as well as removing the pan to replace the filter, clean the pan and magnet. This insures the torque converter, valve body assy(s), clutch packs, lubrication circuits, trans cooler and lines are flushed of as much debris (clutch material, varnish & metal or moisture contamination) as humanly possible. The only Transmissions that didn’t work for or that started slipping afterward were transmissions that were well on their way out and in need a rebuild in the first place. Your repeated stating of “follow the OEM owners manual” is by far the best advise you can give a customer. As far as transmissions that use “lifetime fluid” is just that, once the fluid has been heated to the point of viscosity breakdown it is no longer a good viscosity for lubrication and is now only a friction modifier therefore it needs to be replaced. I’ve got literally hundreds of customers that will state that fact after I showed them the condition of their old fluid and the damage and in some cases the carnage it caused.

[@arthurdolle5257]

Maybe lifetime fluid means when the fluid becomes worn out and contaminated the transmissions dies
