Power train:automatic transmissionApr 26, 1999 · NHTSA campaign 99V089000 · 99,333 vehicles

Model years: 1999

Problem: Vehicle description: passenger vehicles equipped with 4t65e automatic transmissions. 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.

Risk: 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.

Fix: Dealers will replace the manual valve/link assembly with a replacement manual valve/link kit, featuring a spring-type fastener.
