ENGINEERED TO ELIMINATE WARPING, SNAPPED BOLTS, AND TICKING

DODGE 6.7L CUMMINS 13-18 TRANSMISSION

Get the best transmission parts for your 2013-2018 Ram 2500, 3500, 4500, or 5500 with the 6.7L Cummins. We offer everything from complete performance transmission packages to torque converters, valve bodies, rebuild kits, and cooling solutions for the 68RFE and Aisin AS69RC.

  • Built For The Job

    Our complete transmissions are remanufactured with stronger components to handle heavy towing and increased power.

  • Stronger Connection

    Billet torque converters with improved clutches and stators prevent flex and reduce slip for better power transfer.

  • Build It Yourself

    Our Build-It kits include the same heavy-duty clutches, steels, and seals we use in our own performance builds.

  • Cooler & Firmer

    Keep temperatures down and line pressure up with deep sump pans, coolers, and our Protect68 valve body upgrade kits.

WHY TRANSMISSIONS & PARTS FAIL AND HOW BD SOLVES IT

For the common 68RFE transmission, the story is often one of low line pressure leading to premature clutch wear, especially in the underdrive assembly. When you add a tuner, this problem gets worse, often resulting in slipping, high temperatures, and eventually, total failure. Our solutions range from simple, effective pressure control modules like our Electronic PressureLoc and Protect68 kits to comprehensive remanufactured valve bodies, billet flex plates, and heavy-duty torque converters designed to eliminate the 68RFE's most notorious weak points.

  • Slips Between Gears or on Takeoff

    This is often caused by worn clutches and low line pressure in the 68RFE, especially under heavy load or with added power.

    The BD Difference

    A Protect68 kit, valve body, or complete transmission can correct this.

  • Shuddering During Lock-up

    This can indicate a failing torque converter clutch or a warped converter cover.

    The BD Difference

    A BD billet converter is the definitive solution to prevent flex and ensure solid engagement.

  • High Transmission Fluid Temperatures

    Overheating fluid is the #1 killer of automatic transmissions.

    The BD Difference

    A deep sump pan increases fluid capacity, while our cooler bypass delete for 2013-18 trucks guarantees flow to the cooler.

  • Cracked Flexplate

    The stock flexplate is a common failure point when adding horsepower or a multi-disc converter.

    The BD Difference

    Our SFI-approved billet flexplate is engineered to handle massive torque loads without cracking.

What's the difference between the 68RFE and Aisin AS69RC?

The 68RFE is a Chrysler-built 6-speed found in most Ram 2500/3500s. The Aisin AS69RC is a commercial-grade 6-speed, typically found in high-output and Cab & Chassis models from 2013-onward. We offer complete transmissions and components for both.

My truck is stock. What's the best upgrade for my 68RFE?

If your transmission is healthy, increasing pressure and improving cooling are key. A deep sump pan and an Electronic PressureLoc controller are excellent first steps to dramatically improve durability and performance, especially for towing.

What's the purpose of the 2013-2018 Cooler Bypass Delete?

The factory thermal bypass valve often sticks or fails, preventing fluid from reaching the cooler. Our bypass delete ensures full and constant flow to the transmission cooler, significantly lowering operating temperatures.

What's the difference between a RoadMaster, TowMaster, and TorqueMaster transmission?

They are built for different power levels and uses. RoadMaster is a durable OEM+ replacement, TowMaster adds clutch capacity for heavy towing, and TorqueMaster includes a billet input shaft for high-horsepower performance applications.

Can I rebuild my own 68RFE?

If you have the proper skills and tools, yes. Our 'Build-It' kits provide the upgraded clutches, steels, valve body components, and seals needed to build a durable transmission that can handle more power.

Will a new torque converter really make a difference?

Absolutely. A billet BD torque converter for your 68RFE or AS69RC prevents the flex and slippage common to the stock units. This results in more efficient power transfer, lower temperatures, and better throttle response.
