68RFE Solenoid Kit 2003-2010, remanufactured and ready to install. Fits the 68RFE. Ships fast from the USA.
If your 545RFE-equipped Ram 1500, Durango or Grand Cherokee, or an early 6.7L Cummins Ram with the 68RFE, is slamming into gear, flaring between shifts, or dropping into second-gear limp mode, the hydraulic controls are the usual suspect. This listing is a complete 545RFE/68RFE valve body that ships with its solenoid pack already mounted, so the casting, valves and every solenoid arrive as one tested unit for the 2003-2010 run. One note on the name: the store title calls it a solenoid kit, but what you receive is the full valve body assembly with the pack on top, not a loose set of solenoids.
The RFE family has no bands and no throttle valve cable. Every gear is made by one clutch releasing while another applies, and the valve body decides when. The solenoid pack sits on top and turns the transmission computer's commands into oil flow, while the casting underneath holds the pressure regulator, the solenoid switch valve, the low/reverse switch valve and the manual valve. Five pressure switches in the pack report back whether each clutch circuit actually built pressure. On a 2003-2010 unit, the pack also carries the overdrive solenoid that Chrysler later removed. A worn bore in the casting or a tired solenoid coil both end the same way: the computer asks for a shift the oil cannot deliver.
Rule out wiring first. A chafed harness or a corroded case pass-through connector sets the same solenoid codes as a failed pack. Then check line pressure: a healthy RFE at idle should show commanded and actual pressure close together, and a large gap points to leakage inside the valve body. Sonnax has documented that the low/reverse switch valve bore wears from side-loading, and that wear starves the low/reverse clutch until it burns. Our 68RFE valve body problems and testing guide covers the line pressure and reverse checks, and the 68RFE shift solenoid symptoms guide helps you separate an electrical fault from a hydraulic one.
This assembly is listed for select 2003-2010 Dodge, Ram, Jeep and Chrysler vehicles with the 545RFE, and for 68RFE Cummins trucks through 2010. Transmission Digest notes that Chrysler moved to a quieter white-connector solenoid pack in 2004. That white pack is used in all 545RFE units and in the first 68RFEs. Around 2010 the 68RFE picked up running valve body changes and a gray-connector pack with no overdrive solenoid. A 2003 truck, a late-2010 Cummins, or any unit that has been swapped before can sit on either side of those changes. Before ordering, check the pass-through connector color on your old pack and your year, engine and transmission, or send us your year and VIN and we will confirm the match. If your truck already has the gray-connector design, look at the 68RFE valve body for 2010-2018. Every option is in the 68RFE parts collection.
The valve body comes out from under the vehicle once the pan, filter and manual lever linkage are off. Keep the solenoid pack attached to the new casting as supplied. If you ever separate them, the Transend install sheet for RFE valve bodies calls for 53 in-lb on the pack bolts, and overtightening warps the pack and creates its own leaks. Use new pan and filter seals. On a 4WD 6.7L Cummins with the 68RFE, the Doc's Diesel filter and pan gasket kit covers both. Refill with ATF+4 only and set the level hot, since Chrysler service instructions call for about 160 degrees F before checking. Last, run the quick learn with a capable scan tool so the computer relearns clutch fill volumes for the new hydraulics. Skip it and the shifts can stay harsh or soft. If you want a spare pack for a second truck, there is a 68RFE solenoid block pack with filter and gasket kit.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is the whole valve body with the solenoid pack already mounted. You replace the hydraulic casting and the electrical pack in one job instead of chasing them separately.
It is listed for select 2003-2010 545RFE and 68RFE applications, but early units can carry an older connector style. Check the connector color on your old pack or send us your year and VIN, and we will confirm before it ships.
Maybe not. Around 2010 the 68RFE moved to a gray-connector pack without the overdrive solenoid, along with running valve body changes. Trucks with the gray design should look at the 2010-2018 68RFE valve body or confirm by VIN.
Yes. A quick learn is required after install so the computer can relearn clutch fill volumes. Clear stored codes, run the quick learn, and then drive through every gear gently.
ATF+4 only. Check the level with the fluid hot, around 160 degrees F, because a cold check on an RFE reads low and leads to overfilling.
