If you own a 2007.5 and newer Dodge Ram 6.7L Cummins truck with the 68RFE automatic transmission, you may have encountered a critical issue that many truck owners face—a dangerous transmission overflow problem. ATS Diesel Performance has developed a cutting-edge solution, the Doomsday Device Dipstick Overflow Control, to address this concern and prevent catastrophic damage to your engine bay. Designed specifically to combat the risk of hot transmission fluid overflow, this essential component offers reliability, peace of mind, and superior protection for your truck.

Many Dodge Cummins truck owners have received technical service bulletins (TSB) from FCA/Stellantis warning them about a serious risk associated with the 68RFE transmission—transmission fluid overheating and being forced out of the filler tube. This issue occurs when the transmission experiences high internal pressures or failure, leading to the dipstick blowing out and hot ATF fluid spraying onto the turbo and exhaust manifold. This poses a fire hazard that can lead to devastating engine damage or even total vehicle loss.

ATS Diesel Performance recognized this problem and developed the Doomsday Device Dipstick Overflow Control as a simple, yet highly effective solution. This device is engineered to lock securely onto the transmission filler tube and redirect overflowing transmission fluid through a controlled drain tube—preventing dangerous fluid ejections and potential fires.

Key Features and Benefits:

Prevents catastrophic engine fires by redirecting excess transmission fluid away from the turbo and manifold.
Easy, quick installation that takes only minutes with no need for permanent modifications.
Universal fit—works on nearly any application where transmission fluid overflow is a concern.
Eliminates the risk of dipstick blowout, keeping transmission fluid contained and properly vented.
Ideal for high-performance applications, towing, and heavy-duty use.
A must-have for 68RFE transmission owners experiencing pressure-related overflow issues.

The ATS Doomsday Device is designed to be a simple yet effective safeguard against fluid overflow. The unit attaches to the top of the transmission filler tube via a set screw that ensures a tight and secure fit. Instead of the transmission fluid being forcibly ejected through the dipstick tube, the device allows for a controlled release through an external tube that routes excess fluid away from high-temperature engine components.

This means that even in the event of excessive transmission pressure or failure, your Dodge Cummins will remain safe from the risk of engine bay fires and severe damage.

Your Dodge Ram 6.7L Cummins truck is a significant investment, whether you use it for daily driving, heavy hauling, or performance applications. A transmission failure can be one of the most expensive and inconvenient problems a truck owner can face. Worse yet, if a fluid overflow event leads to an engine fire, it could result in a total loss of the vehicle.
