PURPOSE
From March 12, 1988 a new type of automatic transaxle case gasket has been used to provide better case sealing. This improved gasket can be used
during assembly or when repairing a case gasket leak on the described older vehicles, This bulletin describes the gasket upgrade kits and their vehicle
application, and procedures to be used when installing the new gasket on vehicles built prior to March 12, 1988.
AFFECTED VEHICLES

DETAILS OF CHANGE
To improve transaxle sealing, on the above mentioned date the main case gasket was changed in material from rubber impregnated fiber to rubber coated
metal. A typical gasket location is shown. Because the rubber coated metal gasket is thicker than the rubber impregnated fiber one, a gasket upgrade kit
is available. The kit includes a new gasket, an oil pump o-ring, a set of differential spacers, and a set of transfer shaft spacers. The spacers are provided
because a new formula must be used for the differential end play and transfer shaft preload measurements.
