#### BULLETIN COVERS

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 the following vehicles produced between S.O.P. 1988 and October 17, 1987 (Julian Date 289):

A and H cars - THM 440-T4 and 3.8L Engine C and E cars - THM 440-T4 and 3800 Engine N cars - THM 125C and 3.0L Engine

#### SERVICE ACTION

If vehicles are found with flaking paint fill tubes they should be changed along with Transaxle Fluid, Filter, Fill Tube and Fluid Level Indicator.

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.
