Vehicles equipped with listed Ford and GM 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 the valve becomes stuck in the apply position, harsh TCC apply will be the consequence. If the valve is stuck in the release position, no TCC apply or TCC slip will occur. Reconditioning the bore and installing Sonnax oversized TCC regulator valve kit 124740-24K re-establishes correct valve-to-bore clearance, restoring normal TCC operation.

Lengthened spools for additional bore contact support, and sealing
Hardcoat anodized aluminum valves combat premature wear
Annular grooves help center valves in bore to reduce future side-load wear
