Vehicles equipped with Ford Gen. 1, Gen. 2 and Gen. 3 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.
- Lengthened spools for additional bore contact and support
- Hardcoat anodized aluminum valves combat premature wear
- Annular grooves help center valves in bore to reduce future side-load wear
