NHTSA recall 99V089000
Power Train · General Motors, LLC
Details
What's wrong: These vehicles fail to conform to the requirements of fmvss no. 102, "transmission shift lever sequence." A retaining clip, which secures the manual valve to the linkage of the transmission detent lever, can become loose under a combination of possible driver shifting maneuvers and allow the link to become disconnected from the manual valve.
Why it matters: If the link disconnects, the driver's indicated prndl state may differ from the hydraulic state of the transmission. If the driver selects 'drive' and the transmission is actually in 'reverse', a vehicle crash could occur.
The fix: Dealers will replace the manual valve/link assembly with a replacement manual valve/link kit, featuring a spring-type fastener.
