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.
Sonnax valve body layouts provide a detailed overview of individual units making it quick and easy to determine what’s available for the specific valve body you’re working on. See all Sonnax valve body layouts.
Vacuum testing at the port(s) indicated fails to hold the recommended minimum in-Hg, or if wear is visually detected.
