Some 1985 and 1986 Cimarrons equipped with a 125C transaxle may exhibit a noise generated by an interference condition between the plastic cover and the flexplate.
The condition can be eliminated by trimming the converter cover in the area of interference as illustrated below.
For warranty purposes, use operation number T6163 for .4 hours.
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.
