Black paint flakes may be found in the transaxle fluid, bottom pan, fluid level indicator and filter assembly as the result of paint peeling from inside the transaxle fill tube. After the paint peels the unprotected areas of the fill tubes can corrode (interior and exterior), leaving corrosion on the fluid level indicator and the fill tube.
The fill tube paints used on the interior and exterior of the tube may not withstand temperatures over 260 degrees Fahrenheit. Transaxle durability should not be affected in vehicles equipped with these fill tubes, but paint flakes can cause filter clogging over a period of time.
The suspect fill tubes may be found in vehicles produced between October 17, 1987 (Julian Date 289) through June 30, 1988 (Julian Date 184).
If vehicles are found with flaking paint fill tubes they should be changed along with Transaxle Fluid, Filter and Fluid Level Indicator.
Labor Operation Number: T5181 Labor Time: .9
Refer to the On-Car Section of your Service Manual whenever service of the Fluid Level Indicator and Fill Tube is necessary.
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.
