Aisin Seiki AS68RC units often develop converter-related issues caused by excessive wear in the cooler blow-off valve bore located in the upper valve body casting. Once worn, leakage causes low cooler flow, overheated converter fluid and eventually converter damage.
Reconditioning the bore and installing Sonnax oversized cooler blow-off valve 99740-06 re-establishes correct clearances for proper hydraulic functions, salvaging these very expensive and hard-to-find valve bodies.
- Hardened steel valve combats premature wear
- Oversized valve is recalibrated to meet original OE pressures using the OE springs
