Randy's Transmissions JuiceBox 1.0 Thermal Bypass 68RFE-G100 - 2013-2018 Ram 2500/3500 6.7L Cummins (68RFE / Aisin)

Randy's JuiceBox 1.0 transmission thermal bypass

The factory thermostat in the transmission cooler thermal block on 2013-2018 Ram 6.7L Cummins trucks can stick closed. When it does, fluid stops flowing through the cooler and the transmission runs hot. Randy's JuiceBox 1.0 takes the place of that thermostat with a one-piece billet aluminum bypass, so fluid always goes through the cooler.

It's a quick install, and you'll lose about half a quart of transmission fluid or less. Check and top off the fluid once the truck is up to operating temperature.
