Re: 2001 dodge 1500 4x4 governor pressre sensor
Remove the Transmission pan. It is the larger one of the 4 solenoids, it is the rearward one of the set of solenoids. Usually a black color and round like a small pepper shaker. If you are replacing this one, you really should replace them all. This governor pressure sensor, when if fails, usually causes the transmission to start off in 2nd gear and then upshift to other gears is delayed and harsh.

Mounted to the valve body. Remove the transmission pan(messy). On the passenger side of the valve body there are 2 electrical parts. One is the governor pressure solenoid and the other is the governor pressure sensor. The solenoid is in the center of the plate, the sensor is at the side. You have to remove both. You want to replace the sensor. It has the temp sensor built into it.
The governor pressure sensor and solenoid are inside the transmission . remove transmission pan and filter they are on the passenger side solenoid is round and its holding bracket retains the pressure sensor in the valve body. 2 # 20 torx screws
This code is refer for the governor pressure sensor which is located in the valve body of the transmission. If getting power to the sensor and the wires are not open or shorted then the sensor will need to be replaced.
GOVERNOR SOLENOID AND PRESSURE SENSOR REMOVAL
Hoist and support vehicle on safety stands. Remove transmission fluid pan and filter. Disengage wire connectors from pressure sensor and solenoid (see picture) Remove screws holding pressure solenoid retainer to governor body. Separate solenoid retainer from governor (see picture) Pull solenoid from governor body Pull pressure sensor from governor body. Remove bolts holding governor body to valve body. Separate governor body from valve body Remove governor body gasket.
INSTALLATION Before installing the pressure sensor and solenoid in the governor body, replace O-ring seals, clean the gasket surfaces and replace gasket.
Place gasket in position on back of governor body Place governor body in position on valve body. Install bolts to hold governor body to valve body. Lubricate O-ring on pressure sensor with transmission fluid. Align pressure sensor to bore in governor body. Push pressure sensor into governor body. Lubricate O-ring, on pressure solenoid, with transmission fluid. Align pressure solenoid to bore in governor body Push solenoid into governor body. Place solenoid retainer in position on governor Install screws to hold pressure solenoid retainer to governor body. Engage wire connectors into pressure sensor and solenoid Install transmission fluid pan and (new) filter. Lower vehicle and road test to verify repair.
governor pressure above 3psi in gear with 0mph possible causes solenoid pack connector 5v supply circuit open sensor signal circuit shorted to ground or shorted to voltage governor pressure sensor defective transmission fluid burnt or pan has debris valve body valve sticking or defective pcm defective
I have had to replace the governor on those dodge transmissions, and there is a filtering metal mesh screen around the governor inlet port that seems to always get plugged up with small metal shavings. The governor is located under the transmission pan to the rear of the main valve body.
One question? Did you clear the codes out of the system with a scanner? I believe that's the only way to do it now,unlike the old days when you could rest by disconnecting the battery. Hope this helps.
You will need a pressure guage to check line pressure. Governor pressure sensor failure is a common issue. You may want to replace the Sensor, and transducer, also inspect the pan for any debris while it is removed. Make sure to check all electrical connections to the trans, make sure the connectors are clean and corrosion free. There is a pressure test port near the rear of the trans, on the right rear of the case.
if your vehicle is a diesel truck then removed transmission pan. removed transmission filter as well. you will find wiring going to two solenoids side by side. follow harness to other sensor. single solenoid which is located on governor. there will be a square sensor on side, should be black in color. that is your temp sensor. make sure to replace the governor and sensor together. they can be bought seperately but not advisable to just replace temp sensor. should range in price of $200 for both.
I had the same problrm a couple weeks ago I ended up replacing the governor pressure sensor and the solenoid it is very easy you just drop the pan and it is right there. Here is a website that shows you how to do it http://forums.minnesotamud.com/showthread.php?p=48356
It's located under the transmission pan. Once off, you'll see 2 pieces on the passanger side of the valvebody. One is the gov sensor, the other is the gov sonenoid. I recommend replacing them both if your having a governor problem. Remove 4 7/16 bolts and 2 t25 torx screws to remove. Don't tear the gasket on the plate they're in and reuse it. Piece of cake. Trust me, replace them both. 15 year dodge dealer tech.
