Jul 2, 2013 Has anyone done this on their vehicle? Im concerned that Im in way over my head to attempt this. I have the usual check engine line, generic trans code, rough shifting ect. Of course when the light is off, all shifts completely normal. Changed the TPS first with AZ parts, no fix then the more expensive MOPAR TPS. The throttle body is clean, IAC is
newer, the last resort is this governor pressure sensor. So before I go out and buy the MOPAR trans fluid and a new sensor, does anyone have a word(s) of advice? I know to drain, drop pan, remove filter, remove sensor housing, remove "transducer" the the gov press sensor. Do I need to replace the so called transducer?? Also my reverse lights do not illuminate. Where is that sensor? Some guy in a youtube video does it and claims it should only take a half hour. Im the guy that lost
his mind, spending two hours trying to remove a bolt on a mustang caliper finding out that I was turning it the wrong way. Any word of advice would be greatly appreciated. (other than "rightly-tighty, lefty loosey") thanks for your time Joined Dec 18, 2009 · 8,310 Posts
The 4.7 L is coupled to the 5-45RFE transmission. This transmission doesn't have a governor pressure sensor. You will find one in the 42RE transmission, which is coupled to the 4.0 L.

Discussion Starter · #3 · Jul 10, 2013 Thanks Frango! The Jeep dealer went to look up a part number the speed sensors and only came up with a "transducer" part. Using my VIN, they stated that my Jeep doesnt show speed sensors for my trans (2004 JGC V8 4.7 w/tow package). After hanging up the phone with them, I'm not totally convinced of this. Also I had viewed other forums regarding speed
sensors (input & output), most of the folks state that they showed more codes for that being the culprit. My key dance only reveals the general P0700. Thanks for all of your input!

Those jeep dealers (or in fact many of the dealers) have not properly trained personell. The 5-45RFE has certainly two speed sensors, both mounted on the left side of the transmission. The forward sensor is the input sensor and the aft sensor is the output sensor. Joined Jun 28, 2013 · 17 Posts
Discussion Starter · #5 · Jul 14, 2013 Frango, you are the man! I went the Jeep dealer yesterday, $54 a piece for the speed sensors based off recommendation and a hunch. I drove the Jeep for the first time yesterday, 15miles, same crap. Stopped at Autozone, they scanned my OBD, came up with "P0720 - Speed Output Sensor Fault" compared to my "key dance code" of P0700. SO.... hoping that
will be the answer to my woes. Even though the code reveals "output," should I replace "input" as well? If this doesnt do it, I will be forced to deliver her to the deep, perhaps endless money pit.... a trans shop. Im convinced they'll just say I need a rebuild. Ill keep you posted by the way, thanks for the parts link above. Much cheaper Joined Dec 18, 2009 · 8,310 Posts
I think for the price of the part its a good idea to change both speed sensors at the same time. You can never tell how long those sensors will perform well, but a fact is that over time they finally start giving problems. Joined Jun 28, 2013 · 17 Posts
Discussion Starter · #7 · Jul 19, 2013 Frango, nice job! Both sensors changed, reset engine light......shifting like a new Jeep. You also saved me $50 on where to get my parts. Thank you so very much -side note... I had trouble disengaging clip from output sensor, actually damaged the sensor trying to separate the two. I had cleaned and re-connected to the new sensor and it clips on
and off how it should. Also since not driving the Jeep for a month, noticed it was pulling to the right a tad when I test drove, checked my TPS on the fly, all tire pressures were good. Got home after a 4mile drive, front right caliper/pads were smoking. Looks as if my caliper locked up. It's unfortunate since I replaced this caliper last March with new pads. So not "happy Jeeping" just yet. Im going to remove it, push back the piston and re-apply to see what happens, otherwise I may
have a bum caliper from the parts store. ANy thoughts? What does a transmission governor pressure solenoid do?The computer uses the governor pressure solenoid to generate governor pressure relative to road speed, emulating what the hydraulic governor did in older 'RH' series transmissions. The computer varies the duty cycle to the PWM governor pressure solenoid to achieve the desired output pressure.
What does a transmission pressure sensor do?The transmission pressure sensor measures the hydraulic oil pressure in different transmission applications and helps to determine the shifting pressure precisely and reliably.
