About this product

A 68RFE that drops into limp mode on a rough road, sets solenoid or speed sensor codes that clear after a key cycle, or loses a gear only when it rains is very often fighting a damaged harness, not a failed part inside the case. This listing is a used, genuine Mopar 68RFE transmission wiring harness, part number 04801410AE, removed from a 2008 Ram 2500 with the 6.7L Cummins. Note that it is the external harness that runs along the outside of the transmission, not an internal part. It is complete, came off a truck with about 296,000 miles, and has one splice repair, which shows in the photos.

What the transmission harness does on a 68RFE

The 68RFE shifts entirely by computer. Every command to the solenoid pack and every reading back from the speed sensors and pressure switches travels through this harness, plugged into the case at the pass-through connector and at the sensors. The speed sensors on this unit are two-wire generators on twisted-pair wiring, so one chafed wire looks exactly like a dead sensor on a scan tool. The harness lives next to a hot transmission and a crossmember on a heavy truck that gets towed hard, and that is where insulation cracks, clips break and connectors corrode.

Symptoms of a damaged harness

How to confirm before buying

Do not replace a harness on a guess. With a scan tool showing live data, wiggle the harness along the transmission and at each connector; a code or signal dropout on movement is your proof. Unplug each speed sensor and measure across its two terminals, then check each circuit for continuity back to the controller and for a short to ground. Our 68RFE speed sensor guide lays out that test and the P0716 trap, and the 68RFE shift solenoid guide explains why a full set of solenoid codes usually means wiring or power feed, not the pack.

Fitment

This harness came from a 2008 Ram 2500 6.7L with the 68RFE and carries the Mopar label 04801410AE. Trucks from that era use the white pass-through connector solenoid pack; Transmission Digest notes that the 68RFE moved to a gray connector pack in 2010 and a blue one in 2019, so later trucks may need a different harness. Match the part number on your old harness, or send us your year and VIN and we will confirm before it ships. It does not fit gas trucks or 48RE-equipped Rams. See all parts for this unit on our 68RFE collection page.

68RFE Internal Wiring Harness 2008: common questions

Is this an internal harness that goes inside the pan?

No. Despite the product name, this is the external 68RFE transmission wiring harness, Mopar 04801410AE, that runs along the outside of the transmission to the case connector and sensors.

What condition is it in?

Used and complete, from a 2008 Ram 2500 6.7L with about 296,000 miles. It has one splice repair, which is shown in the photos. Plugs and loom show normal age for a truck of that mileage.

Will it fit my 2011 Ram?

Possibly not. The 68RFE changed to a gray connector solenoid pack in 2010 and a blue one in 2019. Match the 04801410AE number on your current harness or send us your year and VIN to confirm.

How do I know my harness is bad and not the solenoid pack?

Watch live data while wiggling the harness and connectors. If codes set or speed signals drop when you move the wiring, it is the harness. Several solenoid codes at once also point toward wiring or power feed rather than the pack.

Do I need a relearn after replacing the harness?

A harness swap by itself does not change any calibration. Clear the codes and road test. If the truck has been in limp mode for a long time or other parts were replaced, a quick learn with a capable scan tool is a good idea.
