- I changed the fluid and filter on my 2016 Sierra to stop the shuttering and improve the shifting. This should be the same for all 8L90 Transmissions in Silverado / Sierra / Tahoe / Denali.

Have you tried to use this pump to extract your oil. I tried in mine and it seems like it doesn’t go all the way down the dipstick tube. I’m not sure if there is something at the bottom of the dipstick tube that catches the dipstick or prevents something other than a dipstick to go down the tube.
Great video. A word of caution replacing the pan. There is a solenoid that can get caught and break the electrical connection. GM had a national hold on that solenoid. It will cost you a valve body to fix it. Ask me how I know.
I had the shudder come on last summer....2018 Silverado, 6.2 litre, 8 sped transmission....took the truck back to my dealer...they flushed and filled with the Mobil 1 synthetic fluid you’re showing...(blue bottle) ....shudder has not returned.....
Appreciate you posting this. Just a quick heads-up... trans temp is supposed to be between 95-113 for fluid check per GM service manual. Also, if you still have the thermal bypass (thermostat) they recommend to bring it up past 190 initially to cycle the fluid through the cooler lines and then let it cool down to check per the above temps. Obviously if you've deleted the thermostat you can simply check when it's at the above range. Great video!
Good video and thorough explanation of everything. My dealer was going to charge me for this service so I had my local mechanic who I trust perform the service. Tried to get away on the cheap so just did the fluid drain and swap but the shudder didn’t go away. Had him swap out the trans filter the 2nd time it was done and this time it worked. 2016 Yukon XL Denali with the same transmission.
My 2019 GMC Sierra slt transmission went out at 12,000 miles . Yes I hate this problem got 16,000 now but still jerks a lil
thanks for this video, i saw last night and the first thing i did this morning was follow step by step and now MY TRUCK BACK TO LIFE!! no SHUDDER!!
Nice job on the video. Many GMC and Chevrolet dealers back in 2016 to 2017, were buying back Trucks and Cars with the 8L90 via the lemon laws. Every state has different lemon laws but GM was buying them back due to the multiple repeat repairs without resolution. This was all because of the Torque Converter Shudder. I remember the dealership I was at originally used the Mobil 1 Black Bottle Fluid, only to have trucks and cars return in like 3000 miles or less with the same complaint. As I recall the Mobil 1 Blue Bottle Fluid came out in 2017 or so and resolved the Torque Converter Shudder immediately and no return complaints. Somewhat surprised you were still able to buy Black Bottle Fluid, as I remember the GM dealers in my area were instructed by the zone office to discard any Black Bottle Fluid due to some dealers still using it and creating repeat customer complaints.
So GM couldn’t just install a drain plug at the bottom of the pan? What a pain !
That is a temporary fix. Dealership did it to my 2020 canyon it was good for about 8000 miles
Great video. I was having the exact same issue on my 2019 Suburban after I had service guy do a service flush. I took it back a week later when the shudder began and they were stumped. After I saw this video I gave them all this info. And now my ride is GTG. Thank you so much for you video.
Great video, and thanks for the update. I plan on doing this soon on my 2016 Sierra Denali 5.3 w/ the eight speed. Keep us updated.
Thanks so much I started to have shifting problems but change it to the mobile one and it shifts like brand new! Awesome video man thanks again!
Thank you for this video. This was very helpful. I just completed this on my truck, hoping the shutter goes away. Next time I’m extracting the fluid, and using a pump sprayer to inject the new fluid, what a mess without!
Excellent video! Thanks for sharing this. My 2017 High Country with 6.2L and 8L90 transmission is exhibiting some of the exact symptoms that you describe. I will be using this video to change mine
Did my 2015 GMC 8L90 with the blue label Mobil1 LV ATF. and so far so good. Shudder free.
I did this on my high country and it worked perfectly. This is a great video and great Information
I changed my fluid. The 1st 1000 miles was good and now the shudder is back. It starts around 37 mph. I have to say thanks for the spray bottle hack. That works really well. I have to get me an extractor though. Those cheap hand pumps work but a PIA to use. Now I have to see what GM is going to do about this. Great channel thanks.
Had this done @ the dealer under warranty and helped the hard shifts. I never did get shutters thought. Starting to act up 45k later so will be doing this again myself. Thanks for the info.
