The dealer has tried several times to fix this problem but it is still there. They have changed the fluid, torque converter, and the fluid again. Still not happy or satisfied.
Has anyone had any luck in getting the problem fixed on their truck? If yes, what did it take? The truck has 46,000 miles on it. Thanks for your response.

Nope, Fluid change and new valve body. 30,000 miles happened since 5000 miles and GMC refuses to fix!

No luck getting my 2017 SS Camaro fixed either. Have had it back to the dealer 3 separate times since purchasing the car. Fluid changed twice, told to drive it and let them know if it continues. It still continues. . .

Purchased new 2019 Colorado Z71 4X4 January 31 2020. Transmission shudder at 500 miles, fluid changed, helped for about 1000 miles. At about 1700 miles it is now slamming into 2nd & 3rd gear when leaving the house in the morning. Sometimes it is very rough shift, other times not so rough. Now at 2200 miles. Called dealer & explained that the shudder is gone, but that it hard shifts mostly on first start up or if it has been sitting. Told I have 36000 bumper to bumper and 5yr/60,000 on powertrain, so if it gets worse I am covered. Really like this 2019 Colorado, just not the shifting. Should have kept the 2015 Colorado, but couldn’t resist the deal of a left over 2019.

does your 5.3 have Active fuel Management or Dynamic Fuel Management? Active Fuel Management gives you the feeling of a shudder with the shut down of cylinders sometimes….Dynamic not so much. It is much smoother.

So is this a shudder like;
1.) driving over a railway track at certain speeds or is it
2.) that sudden downshift like seems the tranny fell out of the truck?
I had both, Alan Jay’s Chev dealership Garage in Sebring, Florida fixed the shudder by flushing out the Torque Convertor, cleaning it up (all day job) and told me to keep a watch on it for next 2 to 300 miles, it cured that BUT the shifting seems to be a bigger problem seems like the Trucks with the 6.2 Engine is more predominant in this problem. Mine is that type but as of late back in Canada seems to not be doing it, we returned end of March because of COVID-19 and border closures.
Usually on the sudden death downshift the garage reaction is “sorry cannot replicate” or “they all do that” my retort is “Fords dont do that”….LOL
Wish to hell I had my Allison Tranny back, it was absolutely GOLDEN!
