Sonnax 99740-04K Features:

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.
