545RFE Governor Pressure Solenoid 2009, new and ready to install. Fits the 545RFE. Ships fast from the USA.
Searching for a 545RFE governor pressure solenoid usually means a 1999-2009 Ram 1500, Durango, Dakota, Grand Cherokee, Commander or Liberty is stuck in second gear, shifting late and hard, or throwing solenoid and line pressure codes. The RFE family never used a governor. What people are really after is the pair of electrical parts that took the governor's place: the solenoid pack that applies the clutches and the line pressure sensor that reports what the hydraulics are doing. This kit gives you both in one box, along with two 2WD filters and a pan gasket, so a single pan drop handles the whole electrical side of the valve body. The pack is listed as interchanging with Mopar 52119435AF and 04799654AC, with manufacturer number 68002342AD.
Older Chrysler rear-drive automatics timed shifts with a hydraulic governor and mechanical shift valves. The RFE threw both out. The computer decides every shift and carries it out by energizing solenoids in the pack bolted to the valve body. The same assembly holds the pressure switches that confirm each clutch actually applied, and the pressure control solenoid that sets line pressure. Chrysler's service information describes a closed loop: the line pressure sensor reports actual pressure, the computer compares it with desired pressure, and it changes the pressure control solenoid duty cycle to close the gap, with line pressure held at a preset 120-135 psi during shifts and in Park and Neutral. If the sensor reads wrong or a solenoid sticks, the computer protects the unit by locking it in a limp gear. In the five-speed 545RFE the pack also has to manage the alternate second ratio, so a lazy solenoid shows up sooner than it would in a 45RFE.
A 545RFE in limp mode is not automatically a bad pack. Low fluid, a damaged 23-pin connector, a worn pump and valve body wear can all set the same codes. Read every stored code and compare desired and actual line pressure on a scan tool. Chrysler's P0932 test checks that actual pressure stays close to desired with the truck held in gear, and checks the sensor wiring for voltage that jumps when the harness is wiggled. Our 45RFE pressure control solenoid guide walks through those readings, and the valve body testing guide covers the hydraulic faults that a new pack will not fix.
This kit is listed for 1999-2009 45RFE and 545RFE transmissions in two-wheel-drive trucks and SUVs. Sonnax notes that the solenoid pack is identified by the color of its 23-pin connector: black in 1999, white from 2000 through the end of the six-solenoid design, and gray when Chrysler dropped a solenoid and two check balls at the 2009-2010 changeover. A six-solenoid pack can service later gray-plug units in many cases, but a gray-plug pack cannot go backward onto an earlier valve body. The filters included are the 2WD versions, so 4x4 owners should tell us before ordering. Match the connector color and part number on your old pack, or send year and VIN and we will confirm it. Browse the rest of the lineup on our 45RFE and 545RFE parts page.
Drain and drop the pan, remove the primary filter, unplug the case connector and remove the pack from the valve body. Install the new pack with clean screens, fit the line pressure sensor, then install the new filter and pan gasket. Refill with ATF+4 only. Chrysler's capacity chart lists about 5.2 liters for a 4x2 pan service, but set the final level hot with the engine running. After the install, clear codes and run the Quick Learn procedure with a scan tool so the computer relearns clutch volumes. If the old fluid was dark or the truck had been shifting harsh for a long time, a 545RFE heavy duty valve body may be the better repair, and the input and output speed sensor kit is worth replacing while the pan is down.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. The governor pressure solenoid belongs to older 46RE, 47RE and 48RE transmissions. The 545RFE does that job with a solenoid pack and a line pressure sensor, which is what this kit contains.
The solenoid pack and sensor are shared across 2WD and 4WD units of the same years, but the filters in this kit are the 2WD versions. Send your year and VIN before ordering a 4x4 and we will confirm what fits.
ATF+4 only. A pan service takes roughly 5.2 liters on a 4x2 truck. Check the final level hot with the engine idling in Park.
Yes. Clear the codes and run the Quick Learn procedure so the computer relearns clutch fill. Skipping it can leave harsh or soft shifts until the adaptives settle.
A gray connector means the later five-solenoid design. The earlier six-solenoid style can often service those units, but confirm your exact year and VIN with us first because the reverse is not true.
