545RFE Overhaul Kit 2002-2012, remanufactured and ready to install. Fits the 545RFE. Ships fast from the USA.
If your Ram 1500, Durango or Dakota with the 545RFE has started dropping into limp mode, holding one gear, or throwing a string of solenoid and pressure switch codes, the electrical heart of the transmission is the first place to look. Despite the overhaul kit name on this listing, what you receive is a pan-down service kit built around a remanufactured solenoid block: the block with its transmission range sensor plate, a two-wheel-drive primary sump filter and grommet, the spin-on cooler return filter and a molded pan gasket. It is the kit for replacing the pack and the filters in one job, not a seal set for a teardown.
The RFE family has no hydraulic governor and no 1-2, 2-3 or 3-4 shift valves. The controller decides every shift and carries it out by firing solenoids in this block, which is bolted to the valve body and plugs into the case through a 23-pin connector. Chrysler describes six electronically controlled clutch solenoids, and the same block carries the variable force line pressure solenoid and the pressure switches that report whether each clutch actually filled. The range sensor contacts read through the same plate, so a worn block can confuse the controller about the shift lever position too. Chrysler's service information says each solenoid circuit is pulse-tested at power-up and every 10 seconds after, and a missing feedback spike sets a code.
Unplug the case connector and look for ATF wicking into the harness, green corrosion or spread pins first, because a bad connection mimics a dead pack. Sonnax gives about 1.3 ohms per shift solenoid and about 3.5 ohms for the pressure control solenoid measured at the connector. Our RFE shift solenoid testing guide covers those checks step by step. If coils test good but desired and actual line pressure disagree, the problem may be the pump or valve body, which the valve body testing guide explains.
The listing is titled for 2002-2012 Ram 1500 and covers the 45RFE and 545RFE, with part numbers listed against Mopar 68002342AD and 68002342AF and the earlier 52119435AB. The pack in the photo has the white connector. Sonnax notes the white-connector block can service 2009 and later units, but the later gray-connector block cannot go back into an earlier truck. The filter in this kit is the two-wheel-drive version and the description says 2WD only, even though one listing field says 4WD, so 4x4 owners should take the solenoid block kit with the 4WD filter instead. Chrysler's capacity sheet shows a 5.2 liter service fill on 4x2 trucks against 6.2 liters on 4x4, which is part of why the filters differ. Send us your year and VIN if you are unsure and we will confirm it. More parts for this unit are on the 45RFE and 545RFE parts page.
If pressure codes stay after the swap, the 545RFE pump is the next part to check. Trucks with burned clutches need a full rebuild, and the RFE master rebuild kit covers that job.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. Despite the listing name, this is a solenoid block service kit: a remanufactured solenoid block with TRS plate, a 2WD sump filter and grommet, a spin-on filter and a pan gasket. It does not include clutch seals or gaskets for a teardown.
The included sump filter is the two-wheel-drive style and the description says 2WD only. For a 4x4, choose our 545RFE solenoid block kit with the 4WD filter, or send us your VIN and we will confirm.
Sonnax notes the white-connector block can service 2009 and later units. The reverse is not true: a gray-connector block cannot go into an earlier truck. Send your VIN and we will confirm your application.
ATF+4 only. After a pan-down service, refill and set the level with the engine running and the fluid at operating temperature.
Yes. Chrysler calls for the Quick Learn after solenoid pack replacement so the controller relearns clutch fill times. Clear codes first, then road test.
