65RFE Governor Pressure Solenoid, new and ready to install. Fits the 65RFE. Ships fast from the USA.
If your Ram 1500, Durango or Grand Cherokee with a 65RFE or 545RFE is setting speed sensor or line pressure sensor codes, shifting erratically, or simply due for a pan service, this kit puts the usual pan-off parts in one box. It is often found under the search term 65RFE governor pressure solenoid, but the RFE family has no governor. What the controller relies on instead are the sensors in this kit: a line pressure sensor (also called the pressure transducer) and the input and output speed sensors. Alongside them you get a 4WD sump filter, a spin-on cooler return filter and a pan gasket, all new.
The 65RFE is the six-speed member of Chrysler's RFE line and shares its case design and control strategy with the 545RFE. The controller compares input shaft speed with output shaft speed to calculate the gear ratio, clutch slip and converter slip, so a weak or noisy speed sensor signal can trigger ratio codes and unwanted shifts even when the clutches are healthy. The line pressure sensor closes the loop on pressure control: the controller commands a duty cycle to the pressure control solenoid, then reads the sensor to see what it actually got. If that reading is wrong, the controller corrects the wrong way and you feel it as harsh or soft shifts. GEARS Magazine points out that the line pressure sensor connector, with faulty solder and crimps at the terminal pins, is one of the most common sources of intermittent pressure codes on these units.
Unplug each sensor and check the connector for oil, corrosion and spread terminals before you condemn the sensor. According to ATSG, the RFE input and output speed sensors are identical and interchangeable, and a new one reads about 535 ohms at room temperature, so a meter quickly finds an open or shorted unit. Speed sensor faults can also come from a missing target or a loose reluctor, which our RFE speed sensor guide explains. For pressure codes, compare desired and actual line pressure on a scan tool and follow our RFE pressure control diagnosis guide; if the sensor checks out and pressure is still wrong, the solenoid pack is the next suspect.
The kit is listed for 45RFE, 545RFE, 65RFE, 66RFE and 68RFE transmissions, with cross references that include 5179267AC, 4799758AF and 05013470AD. The sump filter supplied is the 4WD style. Two-wheel-drive trucks can use a different sump filter in some years, so compare the pickup length of your old filter with the one in this kit before installing, and note that the spin-on filter only applies to transmissions with a cooler return filter port. The sensors are common across the RFE family. If you are not sure, send us your year, drivetrain and VIN and we will confirm the fit. Browse more parts on our 545RFE and 65RFE parts page.
If the codes point beyond the sensors, the gray-connector RFE solenoid block or a full 545RFE/65RFE overhaul kit may be the right next part.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. The RFE transmissions have no governor. They use a line pressure sensor and input and output speed sensors, which are included in this kit, plus the solenoid pack on the valve body.
A 4WD sump filter, a spin-on cooler return filter, a pan gasket, an input speed sensor, an output speed sensor and a line pressure sensor.
On the RFE family they are identical and interchangeable, according to ATSG. A healthy new sensor measures roughly 535 ohms at room temperature.
The kit includes the 4WD sump filter. Some 2WD trucks use a different sump filter, so compare it to your old one or send us your year, drivetrain and VIN.
ATF+4 only. Do not use Dexron or add sealers, and set the final level with the fluid at operating temperature.
