(April 25, 2024)
A group of 13 consumers claims certain transmissions in General Motors vehicles from the last decade are defective and can create unsafe driving conditions, according to a new GM transmission class action.
The plaintiffs say GM’s Hydra-Matic 8L90 and Hydra-Matic 8L45 transmissions manufactured between 2014 and March 2019 can cause vehicles to shudder, lurch forward or have delayed acceleration.
They allege the issues are caused by transmission fluid issues, which can allegedly cause the GM transmissions to fail to purge air properly from valve bodies. This, the class action argues, is the cause of the shudder, lurching and delayed acceleration, as well as overall poor shift quality.
GM class action: Automaker elected not to recall, replace defective transmissionsÂ
The GM transmission issues happen around the time the affected vehicles’ warranties run out, the class action claims. The plaintiffs allege that GM covers fluid flushes for customers who complain about their transmissions during the warranty period, without fixing the underlying issues.
GM engineers asked the company to fix the transmission issues for $305 a vehicle, which would have cost GM about $592 million, according to the lawsuit.
GM instead only replaced the defective transmission in 6,518 unsold Cadillacs and trucks in certain states where it expected customers to complain within warranty, the GM class action claims.
Six drivers filed a 2022 class action lawsuit alleging that several vehicles manufactured by GM are equipped with defective eight-speed transmissions and that GM concealed the defects from buyers for years.

I had that exact same issue and then some 2017 Silverado crew cab Z71 5.3 L. Fortunately for me my extended warranty covered it but still had cost out of my pocket. 47,000 some odd miles. We’re at the time they started around 30 some.

My chevy colorado 8 speed trans had a hard jerking and hard shifting and i had to search for a tsb and had it at the dealership a couple time and they never said anything after i showed them the tsb they didn’t say anything and did a flush and fill every once in a while i still get a jerking on acceleration off of a light but now its out of warranty.
I have a 2018 Colorado which shifts funny sometimes I had it flushed at 35,000 .
I have a 2017 gmc with the same problem called gm I was a thousand miles out of warranty and wanted an arm and a leg to fix it
2018 colorado has the signs that is described above
Dealer flushed fluid but still not right
I have a chevy 3500 transmission that does the exact thing it is a 2019 chevy express 3500
I have a 2016 gmc and I live in Virginia brought it from the dealership in Hopewell and had the same problem
This is not the first time GM has sent bad transmissions into the market. The 2006 to 2013 Chevy Impalas had serious issues as well.
They would slip out of gear unexpectedly at a stop sign and shift erratically.
There was never a recall but there should have…
These transmissions would act up right from the showroom floor or not long after and the dealership would say can’t duplicate the problem.
This is why I no longer drive a GM car.
Yes, I own a 2016 Chevrolet Corvette with a 8 speed Automatic Transmission.
I bought it used, Carfax shows it has a transmission fluid flush. No harsh shifts or shutter. The garage shift is harsh(shifting from park to drive).
