2016 Chevrolet Chevy GM 8L90 8 Speed transmission how to do a fluid and filter change

GM dumb design

[@frankiev-tech4630]

Awesome video my man! Just did this job today! I'm going to help everyone with an additional shop tip! If you remove the nuts to the bottom if the transmission mount...raise housing extension till it feels at a close stop using a jack stand. I used a piece of 2x4 on top of the stand to give you more height! The pan comes off effortless like butter! Oh and instead of using those cheap transfer pumps...I have the Mityvac 7201 for many years. I modified the top hose fitting that's at the top cover with a 1/4 NPT male shop hose to fit your air hose compressor. You need to make an adapter to use a valve lever fitting so you can control the air flow. You don't want that full blast...but just enough like 45psi. Works so much faster than pumping that thing! Worked for me for the past 8 years! Brother you'll save so much time adding that fluid!

[@SwaptimusPrime]

There is a dipstick made aftermarket for the Camaros with 8l. With a little modification it works for the trucks too. I also believe b&m makes one for all.

5 star video, straight to the bone. That’s why i love old school big👍🏾

[@Anthonythesider]

The fluid is suppose to trickle out when you are done not stream out

[@richardkern8916]

It also is supposed to be up to operating temperature between 139 and 141 degrees

[@badass1g]

Yes to both above comments. Aditrionally, this flush should be done 3 times to flush out all the old fluid inside the torque Convertor, not just once.

[@RyanCamaratta]

​@@badass1gdo you change it 3 times back to back and then drop the pan and replace filter last? And what do you need to do in-between those three changes to make sure the TC is flushed as well?

[@SuzukiKid400]

@@RyanCamarattathe idea is that you’re diluting the old fluid each time you drain and refill. After the first flush, the new fluid in the pan mixes with the old fluid in the converter. Then you drive for 500 miles, flush again. Another 500 miles, then flush again. By the third flush, there are only negligible diluted remnants of original fluid remaining. GM used to ask dealers to power flush the transposition with a special machine that connected to the transmission oil cooler lines, but it apparently damaged seals in the tranny so now they prescribe the triple flush.

[@davidreymer217]

Install a universal trans pan drain bolt so you don't have to keep dropping the pan.

[@Trooper33]

I just did this, and even with ratcheting down the exhaust as far as it will go, the pan wouldn’t get past a few parts sticking down. I was able to get the filter out, wipe it all out really well and reinstall. My clearance for hose between the exhaust and tranny was also a lot less than this, so filling when hot was a task.

[@CumminsTurbo4]

Absolutely ridiculously dumb design. GM a joke nowadays

[@LeTigre22]

2017 GMC Sierra 6.2 8L90- had the standard issues little slip from a stop, 1-2 shift and 2-3 were not great. Would bang into 2nd sometimes if going slow downhill…..shuttered at 35mph when cruising. Added the Lube Guard and they stopped shuttering but did not fix the other issues. Fluid was changed 20k miles ago. Decided to go with the Mobile LV HP and it completely fixed everything. I would highly recommend anyone just go ahead and flush it out and put in Mobile LV HP and see what happens.

[@ChristianGarza-z5u]

@LeTigre22 My truck seems to have similar issues and I wanted to try this out. I just wanted to ask if you ended up doing a complete flush out on it as in flushing out your torque converter as well?

[@JamesScruton]

I would like to know if this helped you guys as well

[@jerber8852]

So did you get trans temp up and do a heat temp chek or just cold. Tech manual sez must get trans temp to 125 plus to open valve??

[@ezakoske]

Your Amazon link shows the black labelled bottles, but hopefully they send the blue labelled ones which is supposed to have been reformulated to absorb less moisture.

[@7secondmalibu]

Great video! Unfortunately it appears that clearance between the pan and exhaust varies slightly from vehicle to vehicle. I've been trying for a couple hours now and came across your video. I tried your method several times without any additional luck. It also looks like the sway bar keeps the pan from moving to far forward. I'll try again tomorrow.

[@Gilbertjames007]

How tight do you torque the the screws on the pan once you reinstall it?

[@ronmorosey672]

great video...question if im only replacing 7-8 quarts, is it ok for the small amount of old fluid in the lines and converter to mix with the new , since im not doing a flush? thanks

[@codemansauto208]

yes it will be fine im gonna link a video on cleaning the mas air flow sensor this should be done after you change your fluid

Does anything change when flushing out the fluid if you have the superior solutions bypass mod in the cooler.

[@ichiara07]

im doing my trans fluid service and only 5qts came out of the pan, should i put back exactly what came out or add the extra 2 qts it should have?

[@peachdaddy]

Your supposed to pull the lines off the transmission lines and blow the fluid out of them

[@faustinocervantes9336]

I have a question sir I hope you can help me! My truck just started making like a pop noise and at first i thought I had an exhaust leak and took it to the shop and they said a weld cracked and they welded it back. But I still kept hearing that pop noise like a backfire, so I would let it sit in neutral and rev it but no pops. Then when I’m on the road and gas it I hear pops like little backfires! And I hope it’s not my transmission so you think it may be the torque converter? :(

[@codemansauto208]

the only thing that you are changing when pull in gear and giving it the gas is your putting more pressure on your flex plate I would be looking for a crack in the flex plate

[@christopherochoa6565]

One of the lines for the transmission cooling blew off . It dumped a lot of fluid out. Do I put in 7 or 12 qts back in? 2017 GMC Sierra Denali 8 speed

[@SuzukiKid400]

You keep filling it up until it drains out the check hole when at operating temperature as shown in the video.

[@ronmorosey672]

can i use the same fluid in the transfer case also? thanks

[@codemansauto208]

you need transfer case fluid

[@kenbrake2828]

Great video!

[@jamisoncutaia757]

Extremely helpful. Thank you.

[@ichiara07]

i just did mine and close to 6qts came out, should i add the additional quart and 1/2 for a total of 7 1/2?

[@JFEnterprize]

Been a min but I’d of added extra to be sure. Prob not an entire quart but whatever filled it and resulted in that stream coming out. I’d of assumed when it’s “overflowing” like it does from that full hole you prob don’t want extra in there but it’s likely a 1/4 qt tops. Prob doesn’t hurt. How did you make out?

[@frank12876]

Remember to check the level when the temp is 98 to 113 degrees and plug it back up when it's a dribble idling in park.

[@jaybilawchuk2225]

Are you sure of this for the 8l90’s?

[@frank12876]

@jaybilawchuk2225 from all the research I did. I performed this 6 months ago and it's a daily driver. No issues.

Great explanation 👌 do you add a certain amount of fluid before starting the truck. I understand it has to be at a certain temperature for the fluid to flow

[@codemansauto208]

fill up until it checks full not running, then start up and finish filling from there

[@ronfazer2423]

YES! I am not positive but I think it is 35C-45C.

[@davidndamber2011]

Chevy has a water based transmission fluid right and that's why they recommend it?

[@Stingrayflame]

That saved me about $300 thanks

[@SuzukiKid400]

In Canada, that fluid change is $900!

[@tonyavalos3597]

I have a 2016 Sierra with the 5.3 and can not find a dipstick. This mean mine don’t have it ?

[@JFEnterprize]

Your supposed to go to the dealer and they do a blood transussion type gig to your trans. With a cleaning agent. Your old fluid comes out one end followed by the cleaner then when the new juice starts to flow it’s done.

[@SuzukiKid400]

@@JFEnterprizenot anymore! That machine damages transmission seals

[@JFEnterprize]

@@SuzukiKid400 trans shop said do pan drop and filter changes every 45k to keep it going. Only changes 7 or 8 of the 15 quarts in the 15qt 6 speed system.

Would this be the same for a 1500 ltz 2017 ?

[@robmoss6853]

Did you just reuse the same gasket? Also, I have heard about doing it 3 times to completely and slowly get all the original fluid out. Can you weigh in on that. Thanks again for the video! The dealership didn't want to touch it and a tranny shop wanted me to do it 3 times. I van do it now that I have seen your video.

[@JFEnterprize]

Dealers by me have a machine that does a blood transfusion essentially. With some sorta cleaner added in the middle. Or they pump cleaner in as your old fluid comes out then pump fresh fluid into the trans and when the remainder of the cleaner comes out the tube followed by new juice they pull it. I inquired mo the back on it. Think was 3-500$ job tho still at that. Doesn’t include replacing the filter 😳🫨 so dunno how that works out.

[@robmoss6853]

@@JFEnterprize this is what they wanted to do for mine. I'm old school. If you change the oil, you change the filter.

Just for everyone that is about to do this. You probably will get an error code p0700 after. 😅 disconnect your neg on ur battery n let it sit for five. That reset your tcm.

[@RyanCamaratta]

Why does the TCM need reset?

[@adnanalalawneh1]

Can I do the flush and add a tube of shudder fix , will that help ?

[@rileypup5959]

Yes. If you use the Mobil One Blue Bottle ATF, lube guard is not required. I got immediate results by getting like 6 quarts siphoned out the fill plug and putting in 6 quarts. I did this again like after 5000 miles. The shudder disappeared on my first 6 quart swap. I used one of those oil change siphons to siphon from the fill plug and used a converted pesticide sprayer ($12 at Home Depot and some 3/8 tubing) to fill back up. Don’t use Mobil one Black Bottle ATF or regular Mobil 1 ATF. I could tell the shudder disappeared by seat of pants feel and also by portable scanner/no slippage.

[@JFEnterprize]

@@codemansauto208dealer by me said they use a machine to pump a cleaner into it as your old fluid comes out then fresh fluid till the cleaner comes out. Apparently they don’t replace the filter. 😮 which to me almost defeats the point. Esp if it’s backflushing which I’ve heard will blow your trans and you shove 💩 back into the gears 😵‍💫 thoughts?

[@Pilot_Dad22]

@@JFEnterprizedealer told me the same thing yesterday. They do the flush with the machine and the filter isn’t serviceable. I think they’re lying. Either way I’m doing new fluid every 30-35k miles. Hopefully a flush won’t be so bad with doing it this often.

[@JFEnterprize]

@@Pilot_Dad22 I’d kinda want the filet changed. Did you hear if they push it from top to bottom or bottom to top ie backflush? that’s what scares me 😂 havnt done mine at all and mines at 80k if you do it the recommended every 30k miles I’m guessing you won’t need a new trans at about 110k miles like many say. Prob due to not changing it. Mine seems already to act funny when shifting ect. As a 2019 LD

[@Pilot_Dad22]

@@JFEnterprize I’m not 100% sure how the machine interfaces with the trans to evacuate the fluid but I feel slightly better about them using the machine since I’m doing it more regularly. I would eventually like the filter changed but it sounds like it won’t be getting done through one of these dealers unfortunately. I’m curious what your trans is doing that you say is “funny”. Fwiw mine has always had hard shifts into second when it’s cold. Dealer says that’s normal for these. 🤷🏼‍♂️ I suspect it could be improved with tuning. Originally mine started in with the TC shudder at 32k miles. Dealer flushed it then and that problem has been gone since.

[@jarrodvandermerwe2618]

[@ericeaton9181]

Good video but 7.5qts is overfilled. After sitting over night and not starting I only got 5.5 out. Add 6 and between 131-149*f you drain until it until its just a drip.

[@codemansauto208]

Im glad you saved 20 dollars on fluid but I have never gotten that lucky, I do this for a living and have never used less then 7 quarts in a fluid change both my books call for 7.4 quarts on a fluid and filter change

[@ericeaton9181]

@codemansauto208 I couldn't care less about 20 bucks and I actually went through 12qts by doing it twice. Did you pull the lines to get more fluid? Did you measure the amount you drained? Did you get the transmission to the propped temp before checking because everything I've seen or read says there should not be a stream coming out at all. 🤔

@@ericeaton9181great questions. Just because you do something for a living doesn’t mean you’re doing it right.

[@1pimpmuke4life]

I,ve replaced one before in a 4wd unit. The symptoms was hard jerk when you barley press the gas. Best example I can give is it would feel like picture expecting a smooth reaction from the foot pedal and it randomly snatch you. I believe the converter was 900$ OR 1900$ from the dealer with a hefy core charge. Me and a friend had it done in about 9 hours each. The wire harness and evap is the only thing that will be in the way, and the manner in which it comes down. Theres a non removal frame structure that makes it a challenge.

I was told I had to fill it up until you feel it at the top fill spot. ?? Was I told wrong?!? :(
