68RFE Internal Wiring Harness 2007-2010, used and ready to install. Fits the 68RFE. Ships fast from the USA.
Owners of early 6.7L Cummins Rams usually land here after chasing a shifting problem that will not stay fixed: a new solenoid pack or speed sensor went in, the truck drove fine for a week, and the same limp mode came back. On a 2007-2010 Ram 2500 or 3500 the external transmission harness is a common culprit once the truck has years of heat and road salt on it. This listing is a used, factory OEM 68RFE transmission harness, Mopar P04801410AE, sold as a 2007-2010 Ram 2500/3500 6.7L part. It is the external harness that clips along the transmission, not a component that goes inside the pan, and it is sold ungraded with mileage not recorded, so look over the photos closely.
The 68RFE has no hydraulic shift valves to fall back on. The controller decides every shift and sends it to the solenoid pack through this harness, and it decides based on input speed, output speed and pressure switch signals that come back through the same wiring. One high-resistance terminal can make the controller see a ratio error, call it a slipping clutch, and lock the truck in a limp gear. On the early trucks the harness also has to cross a model-year change: Transmission Digest documents that the original white-connector solenoid pack lost its overdrive solenoid when the gray-connector pack arrived in 2010.
Start with the cheapest checks. Unplug the case connector and look for ATF inside it; fluid in the plug means the case connector seal is leaking and the new harness will soak up the same oil. Then load-test the power and ground circuits rather than just checking voltage with no load, and run continuity and short-to-ground checks from each sensor plug back to the controller. Our 68RFE Ram 2500 common problems guide puts these wiring faults in context with the other known failures, and the Ram 3500 shift problems guide covers sorting electrical faults from mechanical slip.
The listing covers 2007-2010 Ram 2500 and 3500 trucks with the 6.7L Cummins and 68RFE, and the harness carries the Mopar number P04801410AE. Because 2010 was a changeover year for the solenoid pack connector, a 2010 truck in particular should be checked: confirm the number on your old harness matches, or send us your year and VIN and we will verify before shipping. It will not fit 5.9L trucks with the 48RE or any gas-engine Ram. Everything else for this transmission is on the 68RFE parts collection.
If testing shows wiring was not the cause and a clutch pack is slipping, a 68RFE overhaul kit for the 6.7L Cummins is the next step.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is the external 68RFE transmission harness, Mopar P04801410AE, that runs along the outside of the case. The product name says internal, but the part pictured and described is the outside harness.
2007-2010 Ram 2500 and 3500 with the 6.7L Cummins and 68RFE. Match P04801410AE on your current harness, and check a 2010 truck carefully because the solenoid pack connector changed that year. Send your year and VIN if you want us to confirm.
It is a used OEM harness that has not been graded and has unknown mileage. Inspect the photos for loom and connector condition before ordering.
It can be. Wiggle-test the harness with live data, check the case connector for ATF intrusion, and load-test power and ground. If a fault appears when the wiring moves, the harness is the cause.
ATF+4 only. Check the level with the engine running and the fluid fully warm.
