68RFE Solenoid Kit 2004, new and ready to install. Fits the 68RFE. Ships fast from the USA.
A Ram 2500 or 3500 with the 6.7L Cummins that drops into limp mode, shifts erratically, or sets solenoid and pressure switch codes is a common candidate for a new solenoid pack. This kit packages the shift solenoid block (the white-connector design shown in the photo) with a pan filter, a spin-on filter and a pan gasket, so the job is done in one pan drop. The listing places it on the 68RFE as well as the 45RFE and 545RFE that share the same family of pack.
The 68RFE is a six-speed heavy-duty automatic, and its shifts are controlled entirely by the transmission computer through this assembly. The pack bolts to the valve body and holds the shift solenoids that apply and release each clutch, along with the pressure switches that report back whether each circuit actually built pressure. Sonnax describes a five-switch system that the controller monitors, and when a switch disagrees with what was commanded it sets a code and can drop the truck into limp mode. A weak coil, a worn seat or a failed switch all show up as shift complaints even when the clutches are fine.
Transmission Digest's history of the RFE packs explains that Chrysler moved to a quieter pack identified by a white pass-through connector in 2004. That white pack was used in the 45RFE and 545RFE and is what the 68RFE started with. Around 2010 the 68RFE dropped the overdrive solenoid and switched to a gray-connector pack, and in 2019 it moved to a blue-connector pack with a separate TCC solenoid and a new reverse clutch solenoid. The gaskets differ too: Transmission Digest warns that the wrong gasket can cause a bind-up moving forward or a neutral 2-3 shift.
The 68RFE is also known for solenoid switch valve wear, clutch slip while towing, and heat damage. Those can produce some of the same codes, so test before replacing parts.
Read codes and freeze-frame data, check that battery voltage is healthy, and inspect the connector and pass-through for oil or corrosion. A scan tool that shows commanded versus actual pressure switch states will separate a pack problem from a valve body problem. Our 68RFE shift solenoid symptoms and testing guide covers the tests step by step, and the 68RFE valve body testing guide helps rule out switch valve wear.
The listing names 2007-and-later Ram 2500 and 3500 6.7L trucks, plus 45RFE and 545RFE applications in the Dakota, Durango, Ram 1500, Grand Cherokee, Commander, Liberty and Wrangler. It references part numbers 52119435AB, 52119435AF, 5170877AA, 5013470AD, 4799662 and 5179267AC. The deciding check is your old pack: this one has the white connector. If your truck has a gray or blue connector, you need the matching pack from our 68RFE collection. When in doubt, send us your year and VIN.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Only if your existing pack has a white connector. Many later 68RFE trucks use a gray-connector pack and 2019-up trucks use a blue one, so check the connector on your old pack or send us your VIN.
The solenoid block pack, a pan filter, a spin-on filter and a pan gasket, as shown in the photo.
That is when Chrysler introduced the white-connector RFE pack, which the 68RFE used when it launched. The 68RFE itself appears in 2007-up Ram heavy-duty trucks.
Yes. When a pressure switch or solenoid does not respond as commanded, the controller sets a code and can default to a limp gear.
ATF+4. Check the level with the fluid hot, at least 160 F, after the install.
Clear codes and let the controller relearn shift adaptives with a scan tool or a series of drive cycles.
