TRANSMISSION SHIFT CYCLING CRUISE CHECK VALVE REVISION

Some early 1982 Cavaliers equipped with automatic speed control may exhibit transmission shift cycling when encountering an upgrade and/or when the resume feature is actuated.

Vehicles exhibiting this condition can be corrected by replacing the existing three (3) port check valve with a new check valve which has a .035 inch internal restriction. The new three (3) port check valve, P/N 10023289, is light blue in color and is currently available through WDDGM.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
