(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 have an extended warranty and have now had the transmission replaced twice and the same thing is happening again.
I have a 2019 Dodge Grand caravan with the same issues.
Add me I own a 2015 GMC Yukon
I have one of these vehicles. 2005
Trailblazer. Interesting. Had transmission replaced. Also wrote about this truck being in a state which uses salt on the roads in the winter. Nothing ever done with this year. Recall started with 2006 vehicles for electrical fires from fluid entering driver door module causing corrosion resulting in a short in the circuit board. I put out to have all this fixed. My truck is done! Kaput. From SALT! Holes galore underneath. Thanks GM!
I had**** a 2015 gmc yukon 6L80 transmission and had these same problems. It was past warranty so I ended up just buying a new one but I bought one custom built from a local manufacturer in virginia…Definitely didn’t go with jasper…we had issues with them in the past for my husband’s silverado…which also now has a custom built transmission
I have a 2012 Cadillac SRX that does that lurching forward, shuddering and acts like it doesn’t want to go.
