The secondary pressure regulator valve on the Aisin Seiki AS69RC can often wear out. Deterioration at the balance spool end allows for fluid loss resulting in high line pressure, harsh shifts and overheating due to reduced cooler/converter flow. Wear in the boost sleeve can result in converter pressure bleeding into the EPC.
Restore proper hydraulic integrity of the circuit by reconditioning the bore and installing the Sonnax oversized secondary pressure regulator valve kit 122740-28K.

Hardcoat anodized aluminum valve combats premature wear
Highly wear-resistant boost valve sleeve increases life of part
Oversized valve maintains OE pressures
