WHY 68RFE TRANSMISSIONS FAIL AND HOW BD SOLVES IT

From 2007.5 to 2012, Dodge Ram 2500 and 3500 trucks with the 6.7L Cummins engine were equipped with the 68RFE automatic transmission. Its common failure points include burnt overdrive clutches due to low line pressure, a weak stock torque converter, and a fragile input shaft that can break under high torque loads. These issues become more apparent when towing heavy or increasing engine output with performance tuning.

  • Burnt Overdrive Clutches

    A notorious weak point, the OD clutches often slip and burn out under load, resulting in issues shifting into higher gears.

    The BD Difference

    Our TowMaster and TorqueMaster transmissions are remanufactured with stronger clutches for reliable gear engagement.

  • Low Line Pressure

    The factory TCM programming commands insufficient line pressure, which reduces clutch holding power.

    The BD Difference

    Our Protect68 kits and replacement valve bodies increase line pressure to improve shifting and prevent slippage.

  • Torque Converter Failure

    The stock converter can't always handle the Cummins' torque, causing shudder and lock-up slippage.

    The BD Difference

    Our durable ProForce torque converters eliminate shudder and contamination of transmission fluid with clutch material.

  • Broken Input Shaft

    Under high torque from aggressive tunes or heavy loads, the factory input shaft is a common point of failure.

    The BD Difference

    Upgrading to a billet input shaft is essential insurance against a total loss of power transfer.

What is the first upgrade I should make to my stock 68RFE?

Addressing the low line pressure is critical. Installing a BD remanufactured valve body, a Protect68 Pressure Control Kit, or a Transmission Pressure Controller will increase clutch holding power and significantly extend the life of your transmission.

Do I really need a billet input shaft?

If you have added significant horsepower with tuning and other modifications, or if you frequently tow at or near your truck's maximum capacity, a billet input shaft is highly recommended insurance against catastrophic failure.

What is the difference between a TowMaster and TorqueMaster transmission?

Both are fully remanufactured for durability. The TowMaster is ideal for heavy towing with stock or near-stock power, while the TorqueMaster includes additional upgrades like a billet input shaft to handle higher horsepower and torque levels.

Can I build my own performance 68RFE transmission?

Yes. Our 'Build-It' kits are designed for experienced technicians and shops, providing the same high-quality clutches, steels, and components we use in our complete transmission packages.

Why should I install a deep sump transmission pan?

A BD deep sump pan increases fluid capacity, which helps keep the transmission running cooler. The cast aluminum body and cooling fins further dissipate heat, and a magnetic drain plug captures metallic debris.

Do your transmission packages come with a torque converter?

Yes, all of our complete transmission packages include a new or remanufactured BD ProForce torque converter that is matched to the transmission's build level and your truck's application.
