545RFE Solenoid Kit 1999-03, new and ready to install. Fits the 545RFE. Ships fast from the USA.
Owners of early RFE trucks, a 1999-2003 Grand Cherokee 4.7L, an early Durango, Dakota or Ram 1500, usually land here after the transmission drops into second-gear limp mode, sets a solenoid circuit code, or starts shifting erratically when hot. This is a complete service kit built around a genuine Mopar solenoid block, part number 68002342AD (also listed as 68002342AF, 5170877AA and 52119435A, and superseding the 72420 kit). What makes it the right kit for an early truck is the transmission range sensor (TRS) plate in the box.
Early 45RFE and 545RFE units left the factory with a black-connector solenoid pack. That pack is no longer the service part. The listing states the updated white-connector block replaces all black-connector packs only when it is installed with the included TRS plate, which is why this kit is packaged the way it is. Swapping the block without the plate on an early unit is the mistake to avoid.
The block holds the shift solenoids, the multi-select solenoid, the pressure control solenoid and the pressure switches, and it bolts to the valve body. Chrysler's service data describes the six shift solenoids being checked for continuity by an inductive-spike test at power-up and every ten seconds; a failed check sets a circuit code. Sonnax's solenoid identification sheet lists the shift solenoids at roughly 1.3 ohms and the pressure control solenoid at about 3.5 ohms, which is what you measure at the case connector.
Separate electrical faults from hydraulic ones. A circuit code with a resistance reading out of range at the connector points to the block or its wiring. A rationality code is different: Chrysler's P0871 cause list includes check balls, piston seals and the reaction shaft support seal ring, none of which a new block fixes. Our 45RFE shift solenoid testing guide covers the resistance checks, and the pressure control solenoid guide covers line pressure codes.
The listing names these 4WD applications: Aspen 2007-2009; Dakota 2000-2011 4.7L/5.7L; Durango 1998-2011 3.6L/4.7L/5.7L; Raider 2007-2010 4.7L; Ram 1500 2002-2012 3.7L/4.7L/5.7L; Ram 2500 2004-2011 4.7L/5.7L; Ram 2500/3500 2007-2017 6.7L (68RFE); Commander 2006-2011; Grand Cherokee 1999-2004 4.7L and 2009-2011 5.7L; Liberty 2005-2006 2.8L/3.7L; Wrangler 2007-2011 2.8L. The listing calls it a 4WD kit but describes the pan filter as a 2WD filter, so lay the new filter next to your old one before you install it. Note your connector color and send us the year and VIN if anything does not match. Every part for this family is on our 45RFE and 545RFE collection page.
If the codes point at speed or pressure sensing as well, the RFE input, output and pressure sensor kit can go in during the same pan-down job. If the fluid shows clutch material, plan on the 545RFE overhaul kit for 1999-03 instead of a solenoid block alone.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes, that is what the TRS plate is for. The listing states the white-connector Mopar block replaces all black-connector packs when it is installed with the included TRS plate. Install the plate and the block together.
The solenoid block is genuine Mopar, part number 68002342AD, also listed as 68002342AF, 5170877AA and 52119435A. The filters are aftermarket and the pan gasket is a reusable style.
Yes: the primary pan filter with grommet, the spin-on cooler-return filter and a pan gasket are included. Compare the pan filter with your old one before installing, since the listing describes it as a 2WD filter.
Yes. Chrysler requires a Quick Learn after solenoid pack replacement so the computer relearns clutch fill volumes. Without it, shifts can be harsh or flared until it adapts.
Not always. P0871 is a pressure switch rationality code, and Chrysler lists check balls, piston seals and the reaction shaft support seal ring as causes. Rule those out before replacing the block.
