Product Description
The REVMAX 68RFE-929A Transmission Cooler Thermostatic Bypass Upgrade is one of the most effective reliability upgrades you can install on a 2010–2012 Dodge Ram 6.7L Cummins equipped with the 68RFE transmission. These trucks are well known for running hot due to the restrictive factory thermal bypass valve that limits transmission cooler flow.
The factory design restricts cooler flow by as much as 87%, which can lead to excessive transmission temperatures and even transmission failure if the valve sticks closed. The RevMax solution replaces that restriction entirely using ZeroStat Technology, allowing full cooler flow at all times for significantly improved cooling efficiency and transmission protection.
Constructed from Billet 6061 Aluminum, the RevMax bypass module eliminates the failure-prone thermal bypass valve while providing a direct bolt-in upgrade that requires no line cutting or modification.
Key Benefits:
- Up to 87% increase in transmission cooler flow
- Eliminates factory thermal bypass valve failure risk
- Allows the cooler to begin cooling immediately instead of waiting for warm-up
- Billet 6061 aluminum construction for durability
- Integral cooling fins assist with passive heat dissipation
- Direct bolt-in installation – no cutting or modification required
- Allows transmission cooler lines to be flushed using room-temperature fluid
For diesel owners running heavy towing, performance tuning, or hot climates, this upgrade dramatically improves transmission cooling efficiency and overall drivetrain reliability.
Fitment:
- 2010 Dodge Ram 2500 / 3500 – 6.7L Cummins – 68RFE Transmission
- 2011 Dodge Ram 2500 / 3500 – 6.7L Cummins – 68RFE Transmission
- 2012 Dodge Ram 2500 / 3500 – 6.7L Cummins – 68RFE Transmission
Note: Located on the driver side near the fuel filter on certain 2010-2012 trucks.

FAQ
What problem does the RevMax 68RFE bypass upgrade fix?The factory 68RFE thermal bypass valve restricts transmission cooler flow by up to 87%. If it sticks closed, it can cause overheating and even transmission failure. This upgrade eliminates that restriction entirely.
Does this part require cutting transmission lines?
No. The RevMax bypass module is designed as a direct bolt-in replacement. Simply disconnect the factory lines and install them onto the RevMax module.
Will this lower transmission temperatures?
Yes. By eliminating the restrictive bypass valve and allowing full cooler flow immediately, this upgrade significantly improves transmission cooling efficiency.
Can this help with transmission maintenance?
Yes. Because the bypass valve is removed, you can flush the transmission cooler lines using room-temperature fluid without needing a hot flush machine.
Is this compatible with all 68RFE trucks?
This specific model fits 2010–2012 Ram 2500 and 3500 trucks equipped with the 6.7L Cummins and 68RFE transmission.
