42RLE Overhaul Kit 2003-2011, new and ready to install. Fits the 42RLE. Ships fast from the USA.
A 42RLE that leaks at the pan, the output or the shift shaft, or one that is coming apart for frictions after a slip, needs every gasket and seal replaced before it goes back in the truck. This is the KP61900A overhaul kit for the 42RLE four-speed in 2003 through 2011 Chrysler, Dodge and Jeep vehicles, made by Precision International. It is the soft-parts side of a rebuild: the pan gasket, metal-clad lip seals, the valve body and case gaskets, sealing rings and O-rings, including the large rubber rings shown in the photo. Clutch plates and a filter are not in it, so it suits a reseal job or a rebuild where you are sourcing frictions separately.
Every gear in the 42RLE is made by applying a clutch with oil pressure, and there are five of them: underdrive, overdrive and reverse in the input drum, and 2-4 and low/reverse in the case. Each one is only as good as the seals that hold its apply oil. Sealing rings carry fluid from the pump support into the spinning input drum, O-rings and gaskets seal the feeds between the case, the valve body and the piston retainers, and the lip seals keep fluid in at the shafts. After years of heat these rubber parts harden and shrink, pressure bleeds off, and the controller sees a clutch that takes longer to fill. New seals put those circuits back to the volumes the transmission expects.
A simple external leak only needs this kit and a careful reseal. For shift complaints, start with the clutch volume index values on a scan tool; ATRA's bulletin gives the normal range for each clutch, and a number that is high on one clutch tells you where the oil is going. Our slipping-under-load guide explains how worn seals and a leaking input hub bushing raise those numbers. If you have solenoid or electrical codes instead, read the limp mode and solenoid guide before tearing the unit down.
KP61900A is listed for the 42RLE from 2003 to 2011. That covers the 42RLE in the Jeep Liberty and Wrangler, the Dodge Nitro, Dakota and Ram 1500 with the 3.7L V6, and the V6 Chrysler 300, Dodge Charger and Magnum. It is not for the front-drive 41TE or the 45RFE and 545RFE five-speeds. Later 42RLE units added variable line pressure, but the hard parts sealed by this kit carry over; if you are unsure, compare the pan shape and bolt pattern with your transmission, or send the year and VIN and we will confirm it. See every 42RLE and 41TE part on our 41TE collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is the gasket and seal set for the overhaul. Frictions, steels and the filter are bought separately or come in a master rebuild kit.
Yes, the kit is listed for 2003-2011 42RLE units, which includes the 2008 Wrangler automatic. Send your VIN if you want us to double check.
Yes. If the fluid is clean and the shifts are good, replacing the leaking seals and gaskets with this kit is a reasonable repair. Shift complaints should be diagnosed first.
ATF+4 only. Refill to the correct level hot and recheck after a road test.
Yes. Clear codes and run the Quick Learn with a scan tool so the controller learns the new clutch fill volumes.
