Shift concerns in Aisin AW 60-40LE and 60-41SN transmissions can often be traced to wear at the accumulator control plunger valve sleeve. Wear occurs due to continuous movement of the steel valve in the aluminum sleeve as it responds to throttle pressure. Throttle pressure can escape past this wear, negatively affecting accumulator pressure and shift feel. Sonnax accumulator control plunger valve kit 19741-05K restores hydraulic integrity to this circuit for proper pressure control.
