Section: 7A

Date: APRIL, 1989
Subject: EVIDENCE OF PAINT FLAKES IN TRANSMISSION FLUID


Model and Year: 1988 PASSENGER CARS WITH AUTOMATIC TRANSAXLES
TO: ALL CHEVROLET DEALERS


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.

DATE OF PRODUCTION CHANGE:

The suspect fill tubes may be found in vehicles produced between October 17, 1987 (Julian Date 289) through June 30, 1988 (Julian Date 184).

SERVICE ACTION:

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
