Remanufactured 68RFE Transmission

The 68RFE automatic transmission is a staple in Ram 2500 and 3500 heavy-duty trucks, most commonly paired with Cummins diesel engines. These trucks are built to tow, haul, and work hard—but the factory 68RFE transmission has well-known weak points that show up quickly under real-world load.

Converter clutch failure, valve-body wear, and heat-related clutch damage are common, especially on trucks used for towing or commercial work. Spot repairs rarely hold up long-term.

ACE’s remanufactured 68RFE is built to eliminate those failure points, giving your shop a dependable, install-ready solution designed for trucks that still earn their keep.

Built to Fix the Known Weak Points

ACE doesn’t treat the 68RFE like a light-duty transmission. Every unit is rebuilt with upgrades specifically chosen to handle torque, heat, and sustained load.

Key build upgrades include:

  • Upgraded torque converter with improved lock-up clutch material to prevent slip and shudder
  • Reconditioned valve body to correct pressure loss and erratic shifting
  • Improved separator plate and check-ball locations to stabilize hydraulic control
  • Heavy-duty clutch packs and steels using high-energy friction material
  • Precision pump inspection and reconditioning to restore proper line pressure
  • New seals, bushings, bearings, and wear components throughout
  • Full dyno testing under load to verify pressure, shift timing, and converter lock-up

The result is a 68RFE that performs consistently under towing and work conditions—not just unloaded test drives.

Common 68RFE Transmission Failures

If you work on Cummins-powered trucks, these issues are familiar:

  • Torque converter clutch failure or shudder
  • Erratic or delayed shifts, especially 3–4 and 4–5
  • Valve-body wear leading to pressure bleed-off
  • Overheating under load, accelerating clutch wear
  • Premature clutch pack failure on stock builds

ACE corrects these issues during remanufacturing so your shop isn’t chasing repeat problems.

Installation Notes & Best Practices

To ensure long service life and warranty compliance:

  • Flush or replace cooler lines and auxiliary coolers
  • Inspect for debris from previous converter failure
  • Verify line pressure and cooler flow after installation
  • Perform relearn or adaptive procedures if required
  • Use only Mobil 1 ATF or manufacturer-approved equivalent

Skipping these steps often leads to repeat failures—especially on diesel trucks.
