Vehicles equipped with Ford Gen. 1 and Gen. 2 6F35 transmissions can exhibit a number of TCC apply issues caused by bore wear at the TCC regulator valve. Slipping TCC, no TCC apply, fluid overheat and suffering fuel economy are common results of this wear. If valve becomes stuck in the apply position, harsh TCC apply will be the consequence. Installing Sonnax oversized TCC regulator valve kit 144740-19K reestablishes correct valve-to-bore clearances, restoring normal TCC operation.
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.
