2000 Jeep - left turn slip in transmission

42RE Governor Pressure Solenoid and Sensor fix Before you crack the pan on your tranny and dig into the internals I'm going to assume that you have done a fluid/filter change and have already check your kick down linkage to make sure it is properly adjusted. If you have done theses already and your tranny is no better then read on!

If you Jeep came with a 4.0L engine and automatic then most likely the tranny behind it is a 42RE. This is the little brother to the 46RH/RE and though not as heavy duty still it is a tough transmission in its own right.
The E in 42RE is ELECTRONIC control. The Transmission Control Module (TCM) via a solenoid valve and a pressure sensor mounted in the valve body controls the governor pressure.
When it all works, is works great. But when there is a problem with a 42RE the usual suspects are the electrical parts associated with control.
Some of the most common symptoms are erratic shifts and downshifts.
You also might notice very sluggish performance when starting from a stop. This is usually because the tranny is starting in 2nd gear instead of 1st.
If these symptoms describe how your Jeep is behaving first check for trouble codes.
Cycle the ignition 3 times (leave it in the run position on the 3rd) and watch the OD light on the dash. The flashes you see are the codes for the TCM (NOT PCM that is the check engine light) if the codes are a 14, 21, 26; these are related to governor pressure sensor and solenoid problems. But you may have NO codes (a 55) that reveal any problem. That does not mean that there isn't an issue with the electrical internals of the tranny.
Ok, let’s take a look at the usual suspects.


If you drop your transmission pan and remove the filter (prepare yourself for a fluid bath) you should see this (from passenger side of vehicle).
This is the governor body with the pressure solenoid and pressure sensor installed.
To get to the 2 electrical parts you have to remove the governor body.
First things first though. Let’s take a look at the sensor and solenoid.


The solenoid is on the left and sensor on the right. The solenoid is backwardly compatible in all versions of the 42RE but there are 2 versions of the sensor.


There is a 3 pin and a 4 pin version of the sensor. The 3 pin is the early production and is the version in '93-'95 Jeeps (as a rule). The bad news is that this version is very hard to find aftermarket. You have to shell out $120 to the dealership for it. The 4 pin that you see here is the '96 and up version that is widely available from transmission parts distributors for around $40. I would suggest BEFORE you go parts shopping to pull your pan and disconnect the harness and look at what version is in your Jeep! I was surprised to find out that even though I have a '94 ZJ (should have the 3 pin) it had a 4 pin sensor installed. It had been converted to the later version sometime in the past or there was a later model 42RE installed.


To remove the governor body it is 2 hex bolts the same as the ones in the filter, and 4 bolts. First disconnect the 2 connectors, and then unbolt the governor body. (Careful with the gasket!) Carefully remove the governor body. Now that it is out the 2 electrical parts are not difficult to remove.


The metal shield holds the pressure solenoid in. Slide the shield forward, off the solenoid and remove it. The solenoid pulls out.


Take a look at this jewel. It is pretty common for the mesh filter to get clogged and cause problems. But these are not serviceable, just replace it.


The sensor is held in place with a spring keeper. Pop it out with a thin flat blade screwdriver. The sensor pulls out of the side.

Be sure that the new solenoid and sensor are lubed with fluid (o-rings) before they are reinstalled in the governor body.
As a rule these are replaced in pairs. Even if the trouble code says sensor problem, or solenoid problem, replace them at the same time!

Install your new parts and reinstall the governor body just like it all came apart. Hopefully you are replacing the filter also aren’t you?? Get a filter kit with a RUBBER pan gasket, not cork. The rubber is reusable.
It should take you 3 to 4 quarts of ATF+4. ATF+3 has been discontinued because ATF+4 exceeds its ratings. If all you have is ATF+3 you are OK. DO NOT put anything else into you transmissions. DEXRON of any type is NOT compatible with Chrysler 4-speed automatics!!! It is a MYTH that it ever was.
Disconnect and reconnect your battery so the TCM starts with default settings for the new parts. If the problem was the sensor and solenoid you should see a night and day difference in how your tranny shifts.
If you can get both parts from a distributor you can probably do this fix for under $100. But if you have to resort to buying these from a dealership expect them to be in the neighborhood of $120 each. Good Luck!

Additional notes:
There have been cases when all indications point to problems with the solenoid and sensor. But if you have a bad TCM or a bad wiring harness either external or internal to the transmission you can have the exact same symptoms and the procedure in this write-up will not fix the problem. You may want to be proactive when you purchase the parts for this fix. The internal wiring harness includes the overdrive and converter clutch lockup solenoids. You may want to replace ALL the electrical parts at the same time just to save yourself the hassle of cracking the transmission open again. (One fluid bath is enough!)

P1281 code for 2004 jeep grand cherokee freedom

It is not always the T-Stat or sensor! Sorry to revive this old thread, but I have not found this answer anywhere and had to figure it out myself. I Thought it might help somebody else, particularly when a lot of us are not driving as much these days. Low Battery Voltage, due to short trips (Incomplete charging or weak alternator), may affect P1281 and misfiring too. I have had a random misfires for so long that I just clear the codes from time to time. I might not see them for weeks or month at a time, sometime every day or so. Serendipitously, I was going to be away from my jeep for a week and put it on a NOCO 1 amp Minder/Desulfator/Charger. When I got back, I cleared the codes and found P1281 which was new. After charging, no new codes have popped up. So, I started plugging it in every day and my intermittent start up fast idle went away. My temp gauge was not randomly reading low (which was a recent development fitting code P1291) Misfires never seemed to be cylinders that shared a coil (last time it was 1,4 and 6) Over the years, I had already changed the plugs twice (once back to the factory recommended plug), checked the injector circuits, replaced the injectors. Just before last inspection, I Changed the fuel filter/regulator (which magically cleared the codes by itself immediately!) Replaced the Cam sensor (I had a code at the time, my first one several years ago) It is an I6 and has always seemed rough to me. I chalked it up to being and I6, LOL. But my wife felt the difference with the new Filter/Regulator! It has only been 10 days of keeping the battery topped off, but with the temp gauge behaving I am cautiously optimistic. I have read that code P1291 does not always show up under these conditions, So we will see. I know from experience that my 1998 Ram 360 would not idle after it needed a jump until it ran a while with a foot on the gas. My 1998 ZJ 318 is the same. I chalked it up to the voltage being too low to fire the ignition. But I figured once it was running there would be no problem and in those V8 vehicles I never got a misfire or P1281 code. When I would get Misfire codes in my I6 2000 WJ, it always seemed to be right around when it would be going into closed loop, sometimes going in to limp mode just as I was trying to get on the freeway, that was always fun. So IF it comes down to short trip incomplete battery recharge I will be happy, but sad that it hadn't occurred to me sooner.

I would say the alternator. The fluctuations when it is running indicate that the regulator inside the alternator is worn out. The overheating is probably because the cooling fan is not running fast enough or at all.

Where is ignition control module?

The ignition module is located underneath the distributor cap, while the ignition coil is mounted typically on the engine block on the same side about 6-9" away. The center spark plug wire will lead to the coil. The module can be found by removing the distributor cap, there is a wiring harness that plugs into it.

Loud whistling noise while driving.

Does the noise sound as though it is coming from either the front or rear axle and does the noise change as your speed increases. If so it sound as though your axle is whining requiring overhauled if really bad.Common problem

04 Jeep Grand Cherokee Overheating

long answer but should get you solved.

You know for some reason jeep eliminated the FC relay for some models and now relies on the computer to determine when and at what speed the fan should run based on coolant temperature inputs and A/C compressor status. If the fan is not working properly i would consider replacing the fan,
"I have a 04 GC also with the 4.0 and I could not find my FC relay either. Nobody at a local dealer here had ever heard of this phantom FC relay problem. I was able to find an electrical diagram on the web that does not show the FC relay for the 04 GC but that was it. The diagram only showed the PCM and two relays in the PDC near the battery. My GC was overheating now and then. It would seem to overheat when you were in stop and go traffic or letting it idle. I was not losing any coolant so I replaced the thermostat but that did not fix it. After much frustration I started the engine and sat there and watched it run until it began overheating. I paid particular attention to the fan. When the engine began to overheat the fan was barely spinning and would even shut off at times during the overheating. I knew this was not right so that is when I began this search for the FC relay but I could not find it. I disconnected the fan and did some checking on the two speed electric radiator fan. It has a 3 pin connector where the center pin is ground. When I ran power to one pin and grounded the center pin the fan would run. However when I switched the power to the other pin I got nothing. I had already checked operation of the Low and High Speed relays in the PDC near the battery and all checked out so I went and picked up a new radiator fan assembly and installed it. That was yesterday and that fixed the overheating problem. I have concluded that for some reason jeep eliminated the FC relay for some models and now relies on the computer to determine when and at what speed the fan should run based on coolant temperature inputs and A/C compressor status. I also found out that although my GC does not have the towing package it does have the max cooling package. When I went looking for a new motor for the radiator fan at local auto parts store I was asked if it had the towing package and I answered no. Everytime I did they would bring out a motor that only had a 2 pin connector. Not one of them kept the motor that would be needed if you had the towing package. I bet if they did it would have a 3 pin connector on it. So while my GC does not have the towing package I think it has the max cooling package that usually comes with the towing package. I think the standard cooling package uses a one speed fan where the max cooling package uses a two speed fan. It may be that the standard cooling package uses the FC relay which is supposed to be under the passenger headlight but the max cooling package eliminates the relay and uses the PCM to control two relays in the PDC which in turn run the fan. One more thing....replacing the radiator fan assembly involves removing the shroud. One of the 4 screws that holds the shroud is in a very tight space. I fianlly got to it with a long socket extension and swivel. I know this is long but I hope it helps because I was very frustrated at the lack of informartion available locally and on the web in reference to this oddity" (article found on web)

Problem with dual zone heating only one side i

Sounds like the blend door actuator. It separates the driver and passenger side from getting air on the AZC system. Here are some instructions on replacing it:
The passenger side blend door actuator is used on all models equipped with Automatic Zone Control (AZC). This actuator is located on the front of the HVAC housing to the right of the floor panel transmission tunnel and cannot be removed from the passenger compartment without instrument panel or HVAC housing removal.

NOTE: This procedure is for AZC Systems (Passenger side only).

  1. Disconnect and isolate the battery negative cable.
  2. Remove the glove box door. See: Body and Frame\Interior Moulding / Trim
  3. Remove the lower I/P glove box door surround panel.
  4. Remove the dash assembly. See: Body and Frame\Interior Moulding / Trim\Dashboard / Instrument Panel\Service and Repair\Instrument Panel Assembly
  5. Remove the HVAC assembly. See: Housing Assembly HVAC\Service and Repair
  6. Unplug the wire harness connector from the blend door actuator.
  7. Remove the 2 screws that secure the blend door actuator to the HVAC housing.
  8. Remove the blend door actuator from the HVAC housing.
INSTALLATION - AZC (Passenger side only)

  1. In stall the blend door actuator on the HVAC housing and tighten the two mounting screws to 2.2 Nm (20 in. lbs.).
  2. Plug in the wire harness connector to the blend door actuator.
  3. In stall the HVAC unit into the vehicle. See: Housing Assembly HVAC\Service and Repair
  4. Install the instrument panel assembly into the vehicle. See: Body and Frame\Interior Moulding / Trim\Dashboard / Instrument Panel\Service and Repair\Instrument Panel Assembly
  5. Evacuate the HVAC system.
  6. Recharge the HVAC system.
  7. Connect and the battery negative cable.
Hope it helps! If you need more, just send me an email at familyguy77351 at yah I wil be glad to finish helping you with more detail.
