545RFE Overhaul Kit 1999-2018, new and ready to install. Fits the 545RFE. Ships fast from the USA.
Despite the overhaul kit name on this product, you will not find clutch seals or piston rings in the box. It is the electrical half of a 545RFE pan-drop repair: a solenoid block listed as Mopar 68002342AD / 68002342AF, the transmission range sensor plate that rides on the manual lever, a four-wheel-drive pan filter, the spin-on cooler return filter and a pan gasket. The listing covers 1999-2018 RFE units, which on the 545RFE side means the Ram 1500, Durango, Dakota, Grand Cherokee and Commander. It is aimed at the owner whose truck drops into a fixed gear, lights the check engine lamp with solenoid or pressure switch codes, or shifts differently every time the fluid warms up.
Sonnax describes the RFE series as the first Chrysler rear-drive automatic with every shift commanded electronically; there are no shift valves or hydraulic governor deciding gear changes. The 545RFE grew out of the four-speed 45RFE and uses the same pack design. The block on top of the valve body carries the underdrive, overdrive or multi-select, 2C, 4C and low/reverse clutch solenoids, the line pressure variable force solenoid, the pressure switches that report which clutch actually applied, the temperature sensor and the range sensor contacts, all wired through one 23-pin connector in the case. The controller compares what it commanded with what the switches report, and when they disagree it sets a code and holds a default gear to save the clutches.
Read every stored code and the freeze frame, check the fluid level hot, then unplug the case connector and look for oil or bent pins, since a harness fault reads the same as a dead coil. Sonnax publishes the pin-out and coil values: about 1.3 ohms for the shift solenoids and about 3.5 ohms for the pressure control solenoid. A coil far outside those numbers condemns the pack. If the coils test good and the reverse-related codes keep coming back, the problem is likely the switch valve in the valve body rather than the block; our 45RFE/545RFE valve body testing guide and shift solenoid guide show how to separate the two.
Listed for 1999-2018 45RFE, 545RFE, 65RFE, 66RFE and 68RFE transmissions, with interchange numbers 52119435AB/AF and 4799654AC. The year span hides real changes, so check the connector color on your old pack before you order. Per Sonnax, the 1999 pack used a short-lived black connector, white ran from 2000 to 2009 with six solenoids, and gray arrived in 2010 when one solenoid and two checkballs were removed. A white six-solenoid pack can be used on 2009 and later units, but a gray five-solenoid pack cannot be installed on earlier ones. 2019 and later units use a blue connector with a separate converter clutch solenoid and are not covered here. The pan filter is the 4WD style and is also listed for 2WD trucks from 2010 on. Send us your year and VIN and we will match it, or browse the 45RFE/545RFE collection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It contains a solenoid block, range sensor plate, a 4WD pan filter, a spin-on filter and a pan gasket. It has no clutch seals, sealing rings or frictions.
It is listed through 2018. Compare the connector color on your current pack; 2010 and later units used the gray five-solenoid pack. Send us the VIN and we will confirm the match.
The listing starts at 1999, and Sonnax notes the black connector pack was short-lived and not recommended. Send us your VIN so we can confirm the connector on the block in this kit suits your case.
Yes. Run the Quick Learn procedure after replacing the block so the controller relearns clutch fill volumes. Shifts can feel rough until it completes.
ATF+4 only. Chrysler lists a 5.2 L service fill for 4x2 and 6.2 L for 4x4; set the final level with the fluid hot.
