WHY TRANSMISSIONS FAIL AND HOW BD SOLVES IT

The 6.7L Cummins in 2019+ Ram trucks produces immense torque that challenges even the robust factory transmissions. Common failure points in the 68RFE include slipping clutches, pressure loss from a warped valve body separator plate, and broken input shafts on modified trucks. The Aisin AS69RC is tough but still benefits from improved cooling and maintenance when worked hard.

  • Slipping or Burnt Clutches

    Increased power or heavy loads can overwhelm the 68RFE's factory clutches, leading to slipping, delayed engagement, and eventual failure.

    The BD Difference

    Our transmissions use higher-quality clutches with increased counts.

  • Valve Body Cross-Leaks

    The 68RFE valve body separator plate can warp, causing hydraulic fluid to leak between channels. This can cause clutch bind-up, poor shift quality, and damage.

    The BD Difference

    Our ProTect68 kit solves this.

  • Overheating

    Towing heavy grades generates extreme heat, which breaks down transmission fluid and shortens component life.

    The BD Difference

    Upgrading your cooling system is critical for longevity.

  • Broken Input Shaft

    The stock 68RFE input shaft is a known failure point on trucks with significant horsepower and torque upgrades.

    The BD Difference

    A billet input shaft is essential for preventing catastrophic failure in high-performance builds.

What's the difference between a TowMaster and TorqueMaster 68RFE transmission?

Our TowMaster series is designed for heavy hauling and towing with stock to moderately powered trucks. The TorqueMaster series includes a stronger billet input shaft and other upgrades to handle higher horsepower and more aggressive use.

My truck has the Aisin AS69RC. Do you offer upgrades for it?

Yes. We offer complete remanufactured Aisin AS69RC transmissions in Roadmaster, Towmaster, and Torquemaster levels, as well as transmission filter service kits for maintenance.

What does the ProTect68 Gasket Plate Kit do?

The ProTect68 kit adds a gasket between the valve body and separator plate, preventing the common problem of hydraulic cross-leaks that lead to poor shifts and clutch failure in the 68RFE.

When do I need to upgrade to a billet input shaft?

A billet input shaft is highly recommended for any 68RFE application where the engine has been modified to produce significantly more horsepower and torque than stock, as the factory shaft can twist or break under the added load.

What is the benefit of the Cooler Bypass Delete kit?

For 2019+ trucks, our bypass kit deletes the thermal bypass valve, ensuring full-time fluid flow to the transmission cooler. This is crucial for preventing overheating when towing or in hot climates.

What is the 2 Low UnLoc kit?

The 2 Low UnLoc kit allows you to engage your transfer case's low-range gear while keeping the front axle disconnected. This gives you maximum torque for backing up trailers or maneuvering in tight spots without driveline binding on high-traction surfaces.
