Aisin Seiki AS68RC units often develop linear solenoid feed related issues caused by excessive wear in the linear solenoid feed dampeners located in the lower valve body casting. Once worn, these dampeners cause low solenoid feed pressure resulting in multiple shift complaints and concerns. Wear can also cause gear ratio errors and solenoid performance codes related to pressure switch 1 and 2.
Reconditioning these bores and installing Sonnax oversized linear solenoid feed dampener valve kit 99740-05K 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.
