EXTENSION HOUSING BUSHING REPLACEMENT INFORMATION/700R4

All THM 700-R4 transmissions used in 1984 Corvettes will have a roller bearinized extension housing bushing. Because of this roller bearinizing process, the extension housing bushing can not be serviced. If the extension housing bushing requires replacement, the complete extension housing assembly (P/N 8642314) must be used.

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.
