TO CORRECT EITHER CONDITION, INSTALL THE NEW DESIGN CONVERTER CLUTCH STOP VALVE. SEE FIGURE 1. THE NEW DESIGN CONVERTER CLUTCH STOP VALVE CAN BE ORDERED USING PART NUMBER 8634705, AND SHOULD BE USED AS A REPLACEMENT PART FOR ALL THM 200-4R TRANSMISSIONS.

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.
