46RE Internal Wiring Harness, new and ready to install. Fits the 46RE. Ships fast from the USA.
When a Ram, Dakota or Durango with the 46RE will not go into fourth gear, will not lock the converter at cruise, or sets a solenoid circuit code that keeps coming back after the plug is cleaned, the wiring inside the pan is often the real problem. This is a new aftermarket internal harness assembly for the Chrysler RE family: the overdrive solenoid and the converter clutch solenoid on their mounting bracket, the internal wiring, the leads that go to the governor pressure solenoid and sensor, and the round 8-pin plug that passes through the case. The listing covers the 42RE, 44RE, 46RE, 47RE and 48RE, and it ships new in the box from the USA.
The 46RE is still a hydraulically shifted transmission for first through third, so the computer only touches a few things inside the pan. Power and the PCM control wires enter through the round case connector, which the factory service manual shows secured with a small shoulder bolt to the 3-4 accumulator housing. From there the harness runs across the valve body, hooks over the accumulator cover plate, and feeds the overdrive solenoid (the 3-4 shift), the converter clutch solenoid (lockup), and the governor pressure solenoid and sensor that set governor pressure for the 1-2 and 2-3 shifts. Every one of those circuits passes through this harness, so a chafed wire or a cracked case plug can take out shifting that has nothing wrong mechanically.
Start outside the pan. Check the relay feed and the external connector first; the transmission control relay is powered from an engine-running circuit, so test with the engine started, not just key-on. If the codes stay, drop the pan and check solenoid resistance and continuity from the case plug to each solenoid and to the governor connectors while flexing the wires. A wire that opens when moved, a melted plug, or a solenoid out of range means this assembly is the fix. Our 46RE shift solenoid testing guide walks through the checks, and the governor pressure solenoid guide covers the P1762/P1763 side so you do not replace the wrong part.
The listing is written for the RE series (42RE, 44RE, 46RE, 47RE, 48RE) with a round 8-pin case plug, which covers 46RE trucks from Dodge Ram 1500/2500, Dakota, Durango and Jeep Grand Cherokee with the 5.2L and 5.9L V8. The one difference that matters is the governor sensor plug. 1996-1999 transmissions used a round metal governor pressure transducer, and 2000-and-later units moved to a rectangular plastic sensor with a different connector. Compare the sensor connector in our photo to the one on your valve body, or send us your year and VIN and we will confirm before it ships. Every 46RE part we carry is on the 46RE parts page.
For other 46RE faults that look electrical but are not, read 46RE common problems and fixes before you order.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. The listing is the overdrive and lockup solenoid kit with the internal wiring harness attached, as pictured. It does not include the governor pressure solenoid or the governor pressure sensor.
The two groups use different governor sensor connectors: round metal transducer on 1996-99, rectangular plastic sensor on 2000-up. Compare the sensor plug in our photo to yours, or send your year and VIN and we will confirm before shipping.
Most often P0743 (converter clutch solenoid circuit), P0753 (3-4 shift solenoid circuit) and P0748 (governor pressure solenoid circuit). Governor sensor wiring faults can also set P1763 or P1764.
The solenoid bracket screws to the valve body and the harness hooks over the accumulator cover plate, so in practice yes. Pull the valve body, swap the assembly on the bench and reinstall.
ATF+4. Do not use a universal or Dexron fluid in a 46RE.
