Aisin Seiki AS68RC units often develop 2-3 flaired shifts, gear ratio errors and solenoid performance codes related to pressure switch 1 and 2 due to excess wear in the linear solenoid output dampeners located in the lower valve body casting.
Reconditioning the bores and installing Sonnax oversized linear solenoid output dampener valve kit 99740-04K re-establishes correct clearances for proper hydraulic functions and shift control, salvaging these very expensive and hard-to-find valve bodies.
Sonnax valve body layouts provide a detailed overview of individual units making it quick and easy to determine what’s available for the specific valve body you’re working on. See all Sonnax valve body layouts.
Vacuum testing at the port(s) indicated fails to hold the recommended minimum in-Hg, or if wear is visually detected.
