SOLUTION GUIDE

Selecting the right 68RFE build depends on your truck's model year range and whether you require a fresh matched torque converter.

The factory 68RFE transmission behind the 6.7L Cummins is notorious for hydraulic circuit cross-leaks, valve body warpage, and input shaft snapping when subjected to heavy trailer weight or added engine torque. The BD TorqueMaster addresses these fundamental weak links by integrating a heavy-duty billet input shaft, reinforced internal clutch friction packs, and precision-machined hydraulic circuits designed to maintain consistent line pressure under load.

When selecting your build, determine whether a standalone unit or a transmission and converter package best fits your build scope. If your current torque converter is stock, pairing your transmission with BD's matched heavy-duty torque converter ensures proper stall characteristics and multi-disc lockup capacity, preventing contaminated fluid from cycling through your new transmission.

  • Overdrive Clutch Slippage

    Factory hydraulic pressure drop allows the thin 4C and underdrive/overdrive clutch packs to glaze, slip, and overheat under load.

    The BD Difference

    BD adds 33% more overdrive and 2C clutches, backed by QT100 pressure plates that reduce deflection.

  • Input Shaft Fracture

    Shock-loading from exhaust brakes, aggressive tuning, or boosted launches shears the stock two-piece input shaft at the spline junction.

    The BD Difference

    Every TorqueMaster comes standard with a billet input shaft built to handle rapid throttle and high horsepower.

  • Valve Body Cross-Leaking

    Warpage of the OEM aluminum valve body channels causes fluid cross-bleed, dropping line pressure and causing harsh or flared shifts.

    The BD Difference

    A hard anodized valve body and custom bonded-gasket separator plate stop internal cross leaks.

  • Single-Disc Converter Clutch Shudder

    The stock torque converter clutch lacks the surface area to hold lockup against 6.7L Cummins torque, resulting in high heat and shudder.

    The BD Difference

    The ProForce 3D triple-disc converter adds lockup capacity and eliminates warpage from clutch heat.

What is the difference between 2007.5-2018 and 2019-2024 68RFE transmissions?

Ram revised electronic controls, valve body casting passages, and pump components beginning in 2019. The internal hydraulic programming and external connector configurations differ, making proper model-year selection critical.

Why is a billet input shaft standard on the TorqueMaster?

The factory input shaft is a known weak link that easily breaks under torsional load when heavy trailers are coupled with Cummins low-end torque. The billet shaft prevents catastrophic spline shearing.

Should I purchase the transmission alone or the complete package with converter?

If your previous transmission suffered a clutch failure, metallic debris is trapped in your stock converter. We strongly recommend purchasing the complete package to protect the new build and ensure matched holding capacity.

Is a transmission quick-learn required after installation?

Yes. A complete TCM transmission quick-learn procedure using a professional scan tool is mandatory before driving to calibrate clutch volume indexes and prevent premature friction burn.

Do 2019-2024 trucks need tuning for the TorqueMaster?

Yes. 2019-up applications require special tuning to take advantage of the increased line pressure. A line pressure controller is not included.

What torque converter is included in the package?

Packages include the ProForce 3D triple-disc torque converter, featuring HD springs, a stamp forged one-piece cover, thrust bearings instead of plastic thrust washers, a riveted piston, a cast stator, new sprag components and furnace brazed turbine fins.

How do core returns work on BD 68RFE transmissions?

A refundable core charge is applied at checkout. Once your original transmission core is returned complete and undamaged according to BD core criteria, the deposit is credited back.

Are these transmissions emissions compliant?

Transmission assemblies do not alter engine emissions. However, for specific regional, Federal, or California CARB compliance details, please check individual product listings.
