Sonnax 99740-05K Features:

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.
