Owners of 2022 Chevrolet Silverado pickup trucks have been experiencing various 10L90 10-speed automatic transmission issues. This is a separate problem from Chevy’s ongoing issues with its eight-speed automatic, also available in certain Silverado pickups. But finally, Chevy has issued a service bulletin that addresses the erratic and poor shift quality problems. Some also complain about the truck “lurching” after shifts.
What does Silverado “bad shift quality” mean?
The main complaint from Silverado owners is that the shift quality is poor. Especially, between First and Second gear shifts. Additionally, sometimes these shifts can cause the Malfunction light on the dash to come on.
Those trucks affected by the problem are the 2022 Chevy Silverado 1500 pickups, but not the 2022 Chevy Silverado 1500 Limited. The Limited is the pre-facelift version of the 2022 Silverado, which came out in September 2021.
Now, GM dealer technicians are replacing the transmission Control Module and reprogramming the related software. This includes customer cars in for repairs, as well as those sold through a dealer’s inventory. Until the correction is made, dealers cannot sell new and used trucks
Does the Silverado have other transmission problems?
GM also stipulates any trucks without the fix can’t be used as demonstrators. Because the fix does not state whether it is for the eight-speed or 10-speed automatics, owners can use their truck’s VIN number to determine.
Erratic shifting is not the only issue that owners complain about. Transmission fluid leaks and sudden transmission failures are also notable. Chevrolet has already issued a recall for the 2018 Silverado eight-speed transmission. This addresses complaints of sudden downshift into First gear.
Though not specifically connected to automatic transmission problems, there was a recall for 2020 Silverado pickups over driveshaft issues. Certain 1500 and 2500 trucks have driveshafts with compromised welding. This can cause the driveshaft to become out of balance or break at the U-Joint saddle. This can mean something is wrong with the transmission, as any driveshaft vibration can travel through the transmission.
Over 60 technical service bulletins and a class action lawsuit
By the beginning of 2022, GM issued over 60 technical service bulletins for its eight-speed automatic transmission, according to pickuptrucktalk. Now a class action lawsuit is pending against GM. Descriptions like “slipping, bucking, jerking, and kicking” leave little to the imagination. Up to then, GM was mum about the problems, other than replacing some transmissions in the field.
Complaints covered many years of 1500 trucks, going back to 2015, up to the current Silverado and GMC Sierra pickups. It also roped in Corvettes, Camaros, and certain Cadillac models that run identical or nearly identical transmissions. In the lawsuit, it is alleged that “a GM insider said the automaker was aware some transmissions are defective and is working on a kit to fix the fluid starvation problem internally, but has done nothing to inform owners of the potential dangers of erratic shifting.”
So the bottom line is that GM has faced significant owner displeasure with its eight- and 10-speed automatic transmission. When we know more we’ll update this post.
