545RFE Solenoid Kit 2007-2018, remanufactured and ready to install. Fits the 545RFE. Ships fast from the USA.
This listing is more than a solenoid pack. What ships is a remanufactured complete valve body with the solenoid block already bolted on, built for the 2007-2018 RFE family: the 545RFE in Ram 1500, Durango, Grand Cherokee and Commander applications, and the 68RFE behind the 6.7L Cummins in Ram 2500 and 3500 trucks. Buyers usually land here after a truck starts dropping into second-gear limp mode, banging into reverse, losing drive after a shift out of reverse, or setting a cluster of solenoid and pressure codes that a new pack alone did not cure.
The RFE has no hydraulic shift valves in the old sense. The transmission controller fires the clutch solenoids in the pack, and the valve body routes that oil to each clutch while the pressure control solenoid sets line pressure in a closed loop with the line pressure sensor. Pressure switches in the pack report back so the controller knows each circuit actually filled. The valve body also holds the solenoid switch valve, which sends low/reverse solenoid oil to the L/R clutch in first gear and to the converter clutch in higher gears. When that valve or its bore wears, the result is the classic RFE complaint of no drive after reverse or a solenoid switch valve code. Buying the valve body and solenoids as one assembly replaces the bores, check balls and the electrical side together.
Check ATF+4 level hot first, then read codes and compare desired against actual line pressure on a scan tool. Chrysler's own diagnostic for a single solenoid circuit code calls it strictly an electrical fault and warns against replacing the valve body for it, so test coil resistance and the case connector before spending this kind of money. Our 45RFE shift solenoid testing guide covers resistance values and pin checks. If the electrical side passes and you still have switch valve or pressure faults, work through the 45RFE and 545RFE valve body testing guide. A truck that also shows burned clutch material on the pan magnet needs more than a valve body.
The listing covers 2007 through 2018 545RFE and 68RFE units and names interchange numbers 68244707AA, 68244707AB, 68033980AH, 68033980AJ and 68166834AN. Be careful inside that span: Sonnax notes the overdrive solenoid was eliminated in the 2010-2018 version of this valve body, so a 2007-2009 unit and a later unit are not automatically the same part. Count the solenoids on your old pack, compare the connector and the casting with the photos, and match the number on your old assembly. If you are unsure, send us your year and VIN before ordering and we will check it. Other RFE parts are on the 45RFE and 545RFE parts page.
Drain and drop the pan, unplug the case connector, remove the valve body bolts and lower the assembly straight down so the manual valve clears. Clean the pan and magnet, install a new filter, and set the new valve body in place with the manual valve and park rod engaged. Refill with ATF+4 only. Chrysler lists valve body replacement as one of the jobs that requires a Quick Learn with a scan tool, run with the brakes applied, engine above 500 rpm, closed throttle and fluid between 60 and 200 degrees F. Skip it and the shifts will be harsh until the adaptives relearn. If the old fluid was dark, plan on a 545RFE overhaul kit, and if you only need a fresh pack and filter later, the 545RFE solenoid pack and filter kit is the lighter option.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is a remanufactured complete valve body with the solenoid block installed. You are replacing the valve bores, check balls, solenoid switch valve and the electrical solenoids in one assembly.
Not automatically. Sonnax notes the overdrive solenoid was dropped from the 2010-2018 version of this valve body. Match the solenoid count, connector and part number on your old unit, or send us your year and VIN to check.
The listing covers both 545RFE and 68RFE units from 2007 to 2018, including Ram 2500 and 3500 6.7L trucks. Confirm the interchange number against your old valve body before ordering.
Yes. Chrysler requires a Quick Learn after valve body or solenoid pack replacement so the controller relearns clutch fill volumes. Without it, expect harsh or erratic shifts until it adapts.
Mopar ATF+4 only. Chrysler lists ATF+4 as the recommended fluid for the 45RFE and 545RFE, and the 68RFE uses the same fluid.
Possibly. A single solenoid circuit code is usually wiring, the connector or the pack itself. Test those first; this assembly makes sense when switch valve, pressure or worn-bore faults remain after the electrical checks pass.
