2007–2024 Ram Ram 3500 Chrysler 68RFE Transmission Repair
The 68RFE is the automatic behind the 6.7L Cummins in the Ram 3500 from mid-2007 through 2024. High-output 3500s from 2013 onward can instead have the Aisin AS69RC, so we confirm by VIN.
Transmission at a glance
Year-specific notes
- 2007 — 2007 is a split year: mid-year trucks got the 6.7L Cummins and the 68RFE.
- 2010 — 2010 is the first year the heavy-duty trucks were badged Ram rather than Dodge Ram.
- 2019 — 2019 introduced the redesigned heavy-duty Ram, still with the 68RFE on standard-output Cummins.
How to confirm your transmission
- The build sheet / sales code (DG8 / 68RFE) identifies the transmission for your VIN.
- Cummins-powered 2500/3500 trucks are the applications covered here; gas trucks may use a different unit.
- The ID tag on the case confirms the build before parts are sourced.
Common Chrysler 68RFE failure areas in the Ram 3500
Heat is the enemy of the 68RFE; clutch wear and worn seals are common on towing trucks.
Often solenoid pack, valve body or input/output speed sensor related.
Converter clutch wear and fluid condition are checked first.
Front pump seal and cooler line leaks are frequent and can lead to low-fluid damage.
Diagnostic considerations
- Scan codes and review speed sensor, solenoid and line pressure data.
- Check fluid level at temperature and inspect for burnt fluid or debris.
- Loaded road test to reproduce slipping under towing conditions.
Repair or rebuild?
Solenoid, sensor and valve-body faults can often be repaired without a rebuild. Clutch damage, a failed input shaft or debris usually means a rebuild — often with upgraded parts for towing trucks.
