545RFE Overhaul Kit 1999, remanufactured and ready to install. Fits the 545RFE. Ships fast from the USA.
Four-wheel-drive Rams, Durangos, Dakotas and Jeeps with the 45RFE or 545RFE share a common failure: the truck suddenly stops upshifting, the dash lights up, and a key cycle brings it back for a few miles before it happens again. This four-piece kit is aimed at exactly that repair. The listing calls it an overhaul kit, but it is not a seal set. The box holds a remanufactured solenoid block, the deep four-wheel-drive primary sump filter with its pickup tube, the spin-on cooler return filter and a molded pan gasket, so the pack and both filters get done with one pan drop.
An RFE transmission shifts entirely on commands from the controller. There is no governor feeding road speed to hydraulic shift valves; instead the controller reads the speed sensors, decides the gear, and energizes solenoids in this block to fill or exhaust each clutch. Line pressure is set by a variable force solenoid in the same block, and pressure switches tell the controller whether every apply really happened. If one coil opens, or a switch sticks, the controller cannot trust the gear it commanded and defaults to a limp gear to protect the clutches. On a 4x4 the block itself is the same as the 2WD version; what differs is the primary sump filter, and fitting the wrong one is a common service mistake.
Chrysler's service information treats a solenoid circuit code as an electrical fault: the controller pulses each solenoid at power-up and every 10 seconds after, and when the expected inductive spike does not return three times in a row, it logs the code. That makes the connector and harness the first check. Pull the 23-pin plug and look for fluid in the connector and bent or backed-out pins, then measure the coils; our RFE solenoid testing guide has the resistance values. A speed sensor code is a separate failure covered in the input and output speed sensor guide, and the 45RFE and 545RFE problems overview covers the rest.
The pack pictured is the white-connector block labeled 52119435AB, and the listing names it as a replacement for 68002342AD and D72420. Its stated applications include 2002-2012 Ram 1500 3.7L, 4.7L and 5.7L, 2004-2011 Ram 2500 4.7L and 5.7L, 2000-2011 Dakota, Durango through 2011, 2007-2009 Aspen, 2006-2011 Commander and Grand Cherokee 4.7L and 5.7L years. The 1999 in this page title reflects the start of the RFE family, but Sonnax notes the very first 1999 packs used a short-lived black connector, while the white block ran from 2000 through 2009 and can also service later trucks. If yours is a 1999 or has a gray connector, send us the year and VIN before ordering. Two-wheel-drive trucks need the solenoid block kit with the 2WD filter instead. More parts for this unit are on the 45RFE and 545RFE parts page.
A replacement 545RFE oil pan and filter kit is a good add if the stock pan is dented or leaking at the rail.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Four pieces: a remanufactured solenoid block, a four-wheel-drive primary sump filter, a spin-on cooler return filter and a pan gasket. Despite the listing name, it does not include clutch seals or overhaul gaskets.
4x4. The sump filter is the four-wheel-drive version. Two-wheel-drive owners should order the version with the 2WD filter.
The 1999 RFE used a black-connector pack and this block has the white connector. Send us your VIN before ordering so we can confirm whether it suits your truck.
ATF+4 only. Chrysler lists a 6.2 liter service fill for 4x4 RFE trucks. Check the level with the engine running at operating temperature.
Yes. Chrysler lists solenoid pack replacement as a reason to run the Quick Learn, which needs a scan tool that supports it. Clear codes first, then road test.
