Prevent Transmission Fires in Your 6.7L Cummins RAM

The ATS 314-180-2326 Doomsday Device is a must-have safety upgrade for your 2007.5–2024 Dodge RAM 2500/3500 6.7L Cummins with the 68RFE transmission. In response to a known fire risk highlighted by FCA/Stellantis TSBs, where transmission fluid can spray from the dipstick tube onto hot turbo and manifold surfaces during transmission failure, ATS developed this overflow control device.

This billet piece secures to the top of your filler tube using a set screw and reroutes any overflow through a supplied tube, directing it away from critical engine components. Whether you're towing, racing, or running high temps, this small part provides serious peace of mind.
