Modified 4EAT Pump Gasket

A modified 4EAT pump gasket is now available through normal parts channels. The new Part Number is 31339AA121 and can be easily identified because the new gasket material is a coated steel type of gasket. This gasket was incorporated in production since November 1992 starting with the following transmission numbers:

SVX: TRANS # 513102 AND AFTER
LEGACY: TRANS # 527022 AND AFTER
IMPREZA: ALL TRANSMISSIONS





NOTE:
When installing the new type pump gasket on vehicles before the production change you must remove the oil guide plate because it will interfere with the installation of the modified gasket. (See the illustration.)
