A small defect in the 10-speed transmission can cause the rear wheels to suddenly lock while driving. It’s the result of wear in a tiny low-limit valve inside the valve body. Over time, that creates extra strain on the system, leading to harsh shifting and, in some cases, complete lock-up.
Extensive industry research conducted since 2020 has proven the majority of transmission failures stem from problems in the valve body.
The known transmission issue has been reported in the following GM vehicles equipped with the 10-speed automatic transmission:
Affected Transmission Models: 10L80, 10L90 & 10L1000
