SHUDDER DURING 1-2 UPSHIFT OVERSIZED BUSHING 325 TRANS.

SOME 1982 THM 325-4L AUTOMATIC TRANSMISSIONS MAY EXHIBIT A SHUDDER DURING THE 1-2 UPSHIFT. THIS CAN BE CAUSED BY OVERSIZED BUSHINGS IN THE DIRECT CLUTCH HOUSING (REFER TO FIGURE 1). TO DETERMINE IF BUSHINGS ARE OVERSIZED, MEASURE THE INSIDE DIAMETER OF BOTH, AND COMPARE WITH THE DIMENSIONS LISTED BELOW: MAXIMUM ALLOWABLE INSIDE DIAMETERS FRONT - 48.882MM (1.925 IN.) REAR - 44.462MM (1.750 IN.) IF EITHER BUSHING EXCEEDS THE MAXIMUM ALLOWABLE DIAMETER, REPLACE THE DIRECT CLUTCH HOUSING (PART NO. 8632926).

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.
