545RFE Overhaul Kit 1999-03, new and ready to install. Fits the 545RFE. Ships fast from the USA.
Please read this first: although this item is titled as an overhaul kit, what you receive is a Mopar solenoid pack service kit for the 45RFE and 545RFE, listed under OE numbers 68002342AD and 68002342AF. It is the right part if your 1999-2003 Grand Cherokee, Durango, Dakota or Ram 1500 has gone into limp mode, starts off in second, sets solenoid or pressure switch codes, or still carries the troublesome early black-connector pack. It is not a seal and gasket set for a teardown. The kit contains a new white-connector solenoid block with a TRS (transmission range sensor) plate, a sump filter with its grommet, a spin-on cooler return filter and a pan gasket, with instructions.
There are no hydraulic shift valves or governor in an RFE. The transmission computer applies every clutch by switching solenoids in this pack, then reads the pressure switches built into the same block to confirm each clutch actually applied. On the 1999-2009 design the pack holds six shift solenoids, about 1.3 ohms each, plus the pressure control solenoid at about 3.5 ohms that sets line pressure, all fed through one 23-pin connector. Because everything shares one connector and one housing, a single open coil, a leaking pressure switch or a corroded pin can make the whole transmission misbehave.
The year range matters. Sonnax notes the black-connector pack used in 1999 was short-lived and is not recommended for reuse, the white-connector pack ran from 2000 to 2009 and proved reliable, and the later gray five-solenoid pack cannot back-service the earlier units. This kit uses the white-connector design, and the listing states it replaces black-connector packs when the supplied TRS plate is installed with it.
Start electrical. Chrysler service information treats P0750 as a strictly electrical fault, caused by wiring, the controller or an open in the solenoid assembly, and says not to replace the valve body for it. Unplug the 23-pin connector and meter each solenoid against the values above, and inspect the pins for corrosion or push-back. A pressure switch code can be hydraulic, so check fluid level and line pressure before blaming the pack. Our 45RFE shift solenoid testing guide walks through the meter checks, and the pressure control solenoid guide covers line pressure codes. If you also have input or output speed codes, a 45RFE/545RFE speed and pressure sensor kit is worth ordering in the same job.
This page is for 1999-2003 45RFE and 545RFE 4WD applications: the 1999-2003 Grand Cherokee 4.7L, Durango and Dakota 4.7L, Ram 1500 and the 2002 Liberty 3.7L. The original listing also names later 4WD Ram, Durango, Commander and Grand Cherokee models, and Sonnax confirms a white-connector pack can service many later units, but trucks built with the gray five-solenoid pack should be checked with us first. One more detail to match: the listing describes the sump filter as a 2WD style while the kit is titled 4WD, so compare the filter to your pan before installing. Send your year and VIN if you are unsure, or browse the 45RFE/545RFE parts collection for other solenoid kits.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. Despite the title, it is a Mopar solenoid pack service kit: the solenoid block with a TRS plate, a sump filter and grommet, a spin-on filter and a pan gasket. For a full reseal, look at the overhaul and master rebuild kits in our 45RFE/545RFE collection.
Yes, according to the listing the white-connector pack replaces black-connector packs when it is installed with the included TRS plate and the supplied instructions are followed.
Gray-connector units, built from about 2010, use a five-solenoid pack. Sonnax notes a white pack can service many of those trucks, but send your year and VIN before ordering so we can confirm.
ATF+4 only. Top up after the pan is back on, run the engine and check the level with the fluid hot.
Yes. Chrysler calls for the Quick Learn procedure with a scan tool after solenoid pack replacement so the controller resets its clutch values.
