Vehicles equipped with 6T30/40/45/50 (Gen. 1 and 2) and 6T35/31/41/46/51 (Gen. 3 6T40) 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. Installing Sonnax oversized TCC regulator valve kit 144740-16K re-establishes correct valve-to-bore clearances, restoring normal TCC operation.
