45RFE Overhaul Kit 2004-14, new and ready to install. Fits the 45RFE. Ships fast from the USA.
If your 2004 to 2014 Dodge or Jeep with the five-speed 5-45RFE (also called the 545RFE) is coming out for a rebuild, this is a seal and gasket kit sized for that window: Precision International part number KP13900AX. It carries the gaskets, O-rings, rubber seals and small common soft parts a teardown uses up, and it is supplied without the molded pistons. People usually end up here with a Ram 1500, Durango, Dakota, Grand Cherokee or Commander that slips once it is hot, lags into gear in the morning, or keeps leaking after the pan has been resealed. One correction to the generic wording on the listing: this kit holds no friction or steel plates.
The RFE family shifts with five clutch packs and no bands. Three of them (underdrive, overdrive and reverse) are inside the input clutch housing, and the 2-4 and low/reverse clutches apply from the case. To reach the spinning housing, oil from the pump crosses sealing rings on the reaction shaft support and the input shaft, and each piston relies on a rubber seal to hold that oil while its clutch is applied. Heat and age make those seals hard and undersized, the clutch sees less pressure than the controller asked for, and the controller answers by lengthening fill times until it runs out of room. That is when shift flare, ratio codes and limp mode start. This kit replaces the whole sealing layer at once; the pistons are yours to inspect and reuse.
Seals are rarely the first thing to check. Scan for codes and compare commanded and actual line pressure; the 45RFE pressure control solenoid and line pressure guide explains P0868 and P0869 and how the controller closes the loop with its pressure sensor. A worn pump produces the same low readings, so read the 45RFE pump failure guide as well. A delayed engagement after sitting can also be converter drainback through the cooler return filter, covered by Chrysler TSB 21-016-05, which is not a seal problem at all.
The listing covers the 5-45RFE and 545RFE from 2004 through 2014, and the same KP13900AX kit is catalogued for the six-speed 65RFE. Typical applications are the Ram 1500 and Dakota with the 3.7L or 4.7L, the Durango and Aspen, and the Grand Cherokee and Commander with V8 engines. Chrysler used the 45RFE name on four-speed units and revised pistons and seals during this run, and the kit's own notes say coverage varies slightly by platform, so compare each removed piece with its new replacement before installing and send us your year and VIN if anything is unclear. If you have a 1999-2003 four-speed, look at our earlier overhaul kits instead. See everything for this family on the 45RFE and 545RFE parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. KP13900AX contains gaskets, O-rings, rubber seals and small soft parts. It ships without molded pistons, and friction and steel plates are not part of it.
A 2007 Durango with the five-speed 545RFE falls inside this kit's 2004-2014 range. Because seals changed during production, send us the VIN if you want us to confirm before ordering.
The 45RFE is the original four-speed. The 545RFE, also written 5-45RFE, is the five-speed version of the same basic transmission. This kit is aimed at the five-speed units built from 2004 on.
At minimum a filter and the pan gasket or sealant. Add any molded piston that fails inspection, frictions and steels if they are worn, and the pump if its gears or bushings are scored.
ATF+4 only. Expect to use about 14 to 16 liters after an overhaul, then set the level hot and run the Quick Learn.
