FrankBUILT Performance 13-18 68RFE/AS69 Transmission Thermostat Bypass

FrankBUILT Performance 13-18 68RFE/AS69 Transmission Bypass

Improve the performance and reliability of your 2013–2018 6.7L Cummins equipped with the 68RFE and AS69 transmissions using the FrankBUILT Performance Transmission Bypass. Engineered to eliminate restrictive factory flow limitations, this upgrade allows for improved fluid movement, helping maintain proper line pressure and consistent transmission operation.

The factory system can create unnecessary restriction, leading to increased heat and inconsistent shifting—especially in towing or tuned applications. Our bypass solution addresses these issues by optimizing fluid flow, reducing heat buildup, and promoting longer transmission life.

Whether you're towing heavy loads or running performance upgrades, this is a critical modification to help protect and maximize the efficiency of your 68RFE transmission.
