68RFE Cooler Bypass Elimination Block

The MTS Diesel 68RFE Cooler Bypass Elimination Block addresses a common failure point in the stock transmission cooling system. The factory bypass valve is designed to restrict fluid flow to the cooler until the internal transmission fluid reaches 130 degrees, which can lead to excessive heat buildup and potential transmission failure. By eliminating this restriction, this block allows for continuous fluid flow to the external cooler immediately. This upgrade results in more efficient cooling, with reported drops in transmission temperatures by 20-30 degrees. Improved circulation supports better overall torque converter operation and contributes to longer transmission life by mitigating high-heat stress. This part is compatible with 2007-2014 Dodge Ram and Van 1500-3500 series trucks equipped with the 6.7L Cummins diesel engine and 68RFE 6-speed transmission.
