545RFE Tcc Solenoid, remanufactured and ready to install. Fits the 545RFE. Ships fast from the USA.
Most people shopping for a 545RFE TCC solenoid are dealing with a shudder at 40 to 60 mph, a converter that will not lock on the highway, or a solenoid switch valve code. The catch is that the 545RFE does not have a separate lockup solenoid you can unbolt and swap. Converter lockup is run by the low/reverse solenoid in the solenoid pack, and the oil is steered by the solenoid switch valve in the valve body. That is why this listing is the complete assembly: a genuine Chrysler remanufactured 45RFE/545RFE valve body with the solenoid pack already installed, described for 2005 to 2010 Dodge applications including the 5.7L 45RFE.
Chrysler carried the idea over from the 41TE: one solenoid does two jobs. In first gear the solenoid switch valve sends low/reverse solenoid oil to the L/R clutch. After the shift to second the valve strokes the other way and that same solenoid now feeds the torque converter clutch for second through fifth. The computer ramps the solenoid duty cycle up gradually, a stage Chrysler calls partial EMCC, until engine speed and input speed are within about 60 rpm, then applies full lockup. If the switch valve sticks, sticks partway, or its bore is worn, you get lockup shudder, lost lockup, or in the worst cases a no-drive after a shift to reverse, which is one of the best known failures on this transmission.
Pull codes first. Chrysler treats P0750 as strictly an electrical fault and says not to replace the valve body for it, so check the harness and solenoid pack before condemning the whole unit. Switch valve codes and lockup slip with clean wiring are different. Watch commanded versus actual converter slip on a scan tool, and make sure the fluid is full and not burnt. Also keep in mind that the TCC regulator valve and TCC switch valve live in the pump on this family, and Sonnax lists wear there as a cause of TCC slip, so a valve body alone will not fix a worn pump. Our 45RFE shift solenoid guide covers the switch valve codes and the valve body testing guide covers bore wear.
This unit is described for 2005 to 2010 Dodge 545RFE trucks and also 5.7L 45RFE transmissions. Valve bodies and solenoid packs changed during the RFE production run, including the pack connector and the later deletion of the overdrive solenoid, so match the connector and casting of your old unit to the photos, or send your year and VIN and we will confirm. Some units in this run carry an aftermarket separator plate from a shift kit and some do not. You can see every 45RFE and 545RFE part we carry on the 45RFE/545RFE collection page.
If the original failure left debris in the pan, a reman 545RFE pump covers the lockup valves that sit outside the valve body, and the 45RFE transmission cooler is worth a look on trucks that tow, since a slipping converter runs hot.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
There is no separate lockup solenoid on the 545RFE. The low/reverse solenoid in the solenoid pack controls lockup through the solenoid switch valve, which is why this listing is the full valve body with the pack installed.
It is described for 2005-2010 Dodge 545RFE applications and 5.7L 45RFE transmissions. Match your connector and casting to the photos, or send your year and VIN so we can confirm before it ships.
It fixes shudder and lost lockup caused by the solenoid pack or a worn or sticking solenoid switch valve. If the torque converter clutch itself is worn, or the TCC valves in the pump are worn, the shudder will remain.
Yes. Chrysler requires the Quick Learn procedure after replacing the valve body or the solenoid pack. You need a scan tool, the brakes applied and the engine idling with the throttle closed.
ATF+4 only. Fill it to the dipstick, run the Quick Learn, then recheck the level with the fluid at operating temperature.
