General Motors is getting hit by another class action lawsuit over their 8-speed automatic transmissions, which allegedly contain defects and require replacement of some components or complete part replacement.
As per the GM authority, the 8-speed transmission issues allegedly can be traced back to an issue with the torque converter that causes excess friction. Additionally, the lawsuit also refers to 60 technical service bulletins and service updates by GM regarding the 8-speed transmission problems.

The 8-speed GM transmission lawsuit alleges the automaker cannot fix the problems and only a planned major redesign in 2023 models will help. The plaintiffs also claim that GM has known about the problems since 2012 but didn’t admit it to customers.
As per the lawsuit, the 8-speed transmission is covered by an express warranty:
“The warranty covers repairs to correct any vehicle defect, not slight noise, vibrations, or other normal characteristics of the vehicle due to materials or workmanship occurring during the warranty period.”
GM’s warranty covers all defects except for those related to “slight noise, vibrations, or other normal characteristics of the vehicle due to materials or workmanship occurring during the warranty period.”
As per the lawsuit, the transmission problems don’t fall into the excluded categories but GM dealerships told customers that 8-speed transmissions are working normally.
The GM transmission lawsuit also alleges a technical service bulletin (TSB) from August 2020 saying “replacing transmission components or complete assemblies will not improve the condition.”
According to the 8-speed class action, General Motors hasn’t recalled vehicles even though customers have overpaid to fix the problems.
The GM transmission class action lawsuit was filed by these customers:
- Matthew Battle / Georgia / 2020 GMC Canyon
- Juan Castaneda / California / 2021 GMC Canyon
- David Figueroa / New Jersey / 2021 GMC Canyon
