#MOPAR DODGE RAM PRESSURE SENSOR 545RFE TRANSMISSION CODE#

If there is an electrical issue with a shift solenoid, a code specific to that fault should also be displayed. The transmission internal clutches and bands are usually controlled by a solenoid or using fluid pressure. Low or dirty transmission fluid Mechanical failure inside transmission Internal blockage inside transmission main control Faulty Shift solenoid Faulty transmission control module The TCM sets the OBDII code when the Transmission Fluid Pressure Sensor/Switch is not to factory specifications.

The Transmission Control Module (TCM) monitors the Transmission Fluid Pressure Sensor/Switch signal. P0988 - Transmission Fluid Pressure Sensor/Switch 'E' Circuit Range/Performance Possible causes Faulty Transmission Fluid Pressure Sensor/Switch 'E' Transmission Fluid Pressure Sensor/Switch 'E' harness is open or shorted Transmission Fluid Pressure Sensor/Switch 'E' circuit poor electrical connection I bought a OBD3 reader that I thought could perform the quicklearn procedure, but I guess I was wrong, so I would need to find a shop to do that for me, if it's recommended. Transengineer gave good advice about checking wires to see if they are bad, but I do not have a ohm reader.Īny other things I should be looking at? The TCM should be here in 3 days or so, so I can rule that out. I do have a Ram TCM (found for cheap) on the way to swap out and verify that it is or is not the TCM. I checked the wiring harness as best I could from TCM to trans for frayed wires or breaks, and found none. What I have done, is pull plug from TCM, cleaned and inspected, put back in. I have reset the codes 4 times, and just now, is the first time code P0734 popped. I can clear the codes and transmission will shift fine for a bit through all gears, then immediately throw a code and put me into 3rd gear limp mode. Codes that pop up are P0988, and just recently P0734. I'm not shocked, but I removed one part from the equation already. Popped it in(new filters & new atf+4) and had the same problems. I picked up a transmission out of a 2010 dodge 1500 hemi with 20k miles, for cheap. Then CEL came on and went into limp mode.Īfter research and other reasons (I needed the hemi Torque convertor). The next day, the Jeep went back to clunking between 2-3 and 3-2. I stopped and turned the engine off and back on, and Jeep drove like normal the rest of the day. I slowed down and everything appeared fine, and accelerated with a clunk from 2nd to 3rd gear. As I slowed down from 3rd gear to 2nd gear, it slammed into 2nd and shook the Jeep.

I was on highway and slowing down from 60mph to get on freeway on ramp. I have 170k on it and has been flawless till now. I have a 2006 Jeep KJ CRD with the 545rfe transmission.
