2022 Chevrolet pickup truck owners have had several issues with the 10-liter 90 10-speed automatic transmission. This is a separate issue from Chevy’s ongoing issues with the eight-speed automatic transmission, also available on some Silverado pickups. But finally, Chevy has issued a service bulletin that addresses intermittent and poor shift quality issues. About “tottering” the truck after shifts.
What does Silverado mean “poor transmission quality”?
The main complaint from Silverado owners is that shift quality is poor. In particular, between first and second gear shifts. In addition, these shifts can sometimes cause the malfunction light on the dashboard to appear.
. This addresses complaints of abrupt first gear shifting.
Although not specifically related to automatic transmission problems, there has been a recall of 2020 Silverado pickups due to driveshaft issues. Some 1500 and 2500 trucks have driveshafts with poor welding. This can cause the driveshaft to become unbalanced or broken in the U-joint saddle. This could mean something is wrong with the transmission, as any vibration in the driveshaft can be transmitted through the transmission.
More than 60 technical service bulletins and class action lawsuits
By the beginning of 2022, GM has issued more than 60 technical service bulletins for the eight-speed automatic transmission, according to . Now there is a class action lawsuit pending against GM. Descriptions like “sliding, jumping, shiver, kicking” leave little to the imagination. Until then, GM had been silent about the problems, other than replacing some transmissions in the field.
The complaints covered several years from 1500 trucks, dating back to 2015, through to the current Silverado and GMC Sierra pickups. It’s also screwed into Corvettes, Camaros, and some Cadillacs that run identical or nearly identical transmissions. In the lawsuit, it is alleged that “a GM insider said the automaker knew some transmissions were defective and was working on a kit to fix the fluid starvation problem internally, but did nothing to inform owners of the potential dangers of erratic shifting.”
So the bottom line is that GM ran into a lot of owners’ dissatisfaction with its eight and ten-speed. When we know more we will update this post.
