46RE Tcc Solenoid 1996-99, new and ready to install. Fits the 46RE. Ships fast from the USA.
On a 1996-1999 Dodge Ram, Dakota, Durango or Jeep with the 46RE, 47RE or 42RE, the torque converter clutch solenoid is not sold by itself. It shares a bracket with the overdrive solenoid and is wired into the internal harness and round case connector, so when lockup quits or fourth gear disappears, this whole assembly is the service part. This is a new Mopar overdrive and lock-up solenoid assembly with harness for the 1996-99 A500 and A518 family, built with the round 8-pin case plug those years use.
The 46RE shifts first through third with governor pressure, but fourth gear and converter lockup are purely electrical. The overdrive solenoid has one job: it makes the 3-4 shift. The TCC solenoid applies the converter clutch through the switch valve once the PCM decides conditions are right. Both get battery voltage through case connector pin 1 from the transmission control relay, and the PCM turns each one on by grounding it. Lose that pin 1 feed and the unit drops into limp mode; lose one solenoid and you lose only its job, which is what makes the symptoms easy to read.
Start the engine first: on these trucks the transmission control relay coil is only fed with the engine running, so key-on solenoid checks read dead even on a good system. Then measure each solenoid at the case connector. ATSG gives 25 to 40 ohms as the general overdrive and TCC solenoid range, while Transmission Digest documents two lockup solenoid designs across the family, a white-connector unit around 1-1.6 ohms and a blue-connector unit around 13-24 ohms. They are not interchangeable, so compare readings against each other and against what came out. Rule out cooler restriction, which Sonnax calls the most common cause of lockup performance codes, and a worn switch valve. Our 46RE shift solenoid testing guide covers the pinout and the white-versus-blue trap, and the cooler line guide covers flow problems.
Listed for 1996-1999 A500 (42RE and 44RE) and A518 (46RE) transmissions, which also covers the 47RE in 1996-99 Cummins Ram 2500 and 3500 trucks, in Ram 1500-3500, Dakota, Durango and Jeep Grand Cherokee applications. The identifying feature is the round 8-pin case connector; 2000-and-later units changed the governor sensor connector and harness, so a 2000-up truck needs its own version. Hold your old assembly next to the photo, check the plug and the lockup solenoid connector color, or send us your year and VIN. The full lineup is in our 46RE parts collection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Not for these years. The TCC and overdrive solenoids are part of the internal harness and case connector assembly, so the assembly is the replacement part.
No. This assembly is for 1996-1999 units with the round 8-pin plug. 2000-and-later trucks use a different harness version; send us your VIN and we will point you to the right one.
Possibly. With the engine running, check for power at case connector pin 1 and back-probe the overdrive control wire on a road test. If the PCM never commands fourth, chase its inputs, such as the OD cancel switch, instead.
Two lockup solenoid designs exist, a white-connector low-resistance and a blue-connector high-resistance version, and swapping them causes shudder, surge and slip codes. Match the connector color and resistance to the original.
ATF+4 only. No programming is needed; clear codes and road test.
