6R140 Oversized TCC Apply Regulator & Boost1 Valve Kit
Ford 6R140 transmissions often display TCC-related concerns due to deterioration in the TCC apply regulator bore and boost assembly. As wear progresses, pressure loss causes various symptoms to arise such as TCC slip, no lockup, insufficient cooler or lube pressure, overheated fluid, suffering fuel economy and/or TCC codes. Restore normal TCC operation and restore cooler/lube flow by reconditioning the bore and installing Sonnax oversized TCC apply regulator and boost valve kit 126740-15K.
