REVERSE GEAR SHUDDER OR VIBRATION 1986 TORONADO

Some 1986 Toronado models may experience a shudder or vibration in reverse. This may be caused by contact between the engine mount (location 1, Figure 1) and exhaust heat shield or by a grounded condition of the safety pin in the RH transaxle mount (location 2, Figure 1).

If there appears to be contact between the engine mount and exhaust heat shield, the engine mount should be replaced with a new engine mount, pan number 17986962, which is available from 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.
