FrankBUILT Performance 19+ 68RFE/AS69 Transmission Thermostat Bypass

FrankBUILT Performance 19+ 68RFE/AS69 Transmission Bypass

Upgrade the reliability and performance of your 2019+ 6.7L Cummins equipped with the 68RFE and AS69 transmissions using the FrankBUILT Performance Transmission Bypass. Designed to improve fluid flow and reduce restrictive factory limitations, this bypass helps maintain proper line pressure and transmission efficiency—especially in high-performance or heavy-duty applications.

The factory system can create unnecessary restriction and heat buildup, which can lead to premature wear and inconsistent shifting. Our bypass solution eliminates those weak points, allowing for smoother operation, better cooling efficiency, and increased transmission longevity.

Built with durability and performance in mind, this is a must-have upgrade for trucks running tuning, towing heavy loads, or upgraded transmission components.
