44RE Tcc Solenoid 1996-1999, new and ready to install. Fits the 44RE. Ships fast from the USA.
A 1996-1999 Jeep Grand Cherokee 4.0L or Dodge Dakota that revs high on the highway because the converter never locks, or that stays in third when it should drop into overdrive, usually has a problem in the solenoid pack on the valve body. This set is built around the lock-up and overdrive solenoid assembly with its main internal wiring harness, and it adds the parts that share that harness on these years: the governor pressure solenoid, the 4-pin oval-connector governor pressure transducer and the governor solenoid gasket. Part numbers on the listing are 22954B, 22958 and 22955, cross-referenced to 12420B, 12415B and 12432A and to the factory 52118500, 52118652, 56027720 and 4617210 numbers.
The 42RE and 44RE build first through third gear hydraulically, with the governor circuit deciding the 1-2 and 2-3 shift points. The two coils on the lock-up and overdrive bracket handle the rest. The overdrive coil makes the 3-4 upshift and nothing else. The TCC coil redirects converter oil so the lock-up clutch applies, normally in fourth, or in third when overdrive is switched off. One feed wire powers both coils through the round case connector, and the PCM grounds each one when it wants it on. On 1996-1999 units the same harness also runs up to the governor sensor and solenoid, which is why these years are usually serviced as a set.
Unplug the round case connector and measure each coil. The ATSG figure for the RE-series overdrive and TCC solenoids is 25 to 40 ohms, so an open coil or a dead short settles it. Then verify battery voltage on the feed pin with the engine running and watch the PCM ground each coil. If the electrical side passes and the converter still will not hold, look at the hydraulics: a restricted cooler and a worn switch valve are both known causes of lock-up codes on this family. Our RE shift solenoid testing guide covers the coil checks, and if fourth gear is the only complaint, the no-overdrive diagnosis guide lists the mechanical causes to rule out.
This is the 1996-1999 version. Its harness and sensor use the early oval 4-pin governor transducer connector, and it will not plug into the rectangular plastic sensor that arrived with 2000-up valve bodies. For those, use the 2000-on lock-up and overdrive solenoid set. The listing's application chart includes 1996-1999 Grand Cherokee 4.0L, 1996-1999 Dakota and Durango with the 2.5L, 3.9L, 4.7L and 5.2L, 1998-1999 5.9L models, and 1996-1999 Ram 1500 and vans; several of those carry the larger 46RE, which uses the same parts. A unit that has been rebuilt or had its valve body changed may not match its model year, so drop the pan and check the sensor connector before ordering, or send us your year and VIN. The rest of the A500 family is on our 44RE parts page.
No relearn or programming is needed for these parts.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
A lock-up and overdrive solenoid assembly with the main internal wiring harness, a governor pressure solenoid, a 4-pin oval-connector governor pressure transducer and a governor solenoid gasket.
No. This set uses the early oval-connector governor sensor. 2000-up valve bodies use a rectangular plastic sensor, so order the 2000-on solenoid set instead.
On these units the lock-up and overdrive coils are one bracket and harness assembly, so the assembly is the service part. This set also covers the governor parts that share the harness.
ATSG lists 25 to 40 ohms for each coil, measured through the case connector.
Check cooler flow and the valve body switch valve. Both can keep the converter clutch from applying even with a good solenoid. A worn converter clutch is the last item to check.
ATF+4. Check the level hot in neutral after the install. No relearn is required.
