#826 of 1101 2003 Jeep Grand Cherokee - won't shift into reverse
Jun 08, 2011 (6:52 pm)
Have a 2003 JGC Laredo 4x4 inline 6 with 107,500 miles. Haven't had any major mechanical problems with it and have owned it for two years. Just within the last couple of months it has been making almost a grinding sound when shifting into reverse in the morning after sitting at night and shaking. It will stop and run fine if I put it into another gear then back in reverse. Well tonight it decided that it doesn't want to go back into reverse anymore. It's never slipped gear so we don't think the whole transmission is going out, and all of the 4x4 gears work fine - except for reverse. It doesn't make the usual regular shifting noise when you put it into gear for reverse, and when you rev it sounds and feels like you're just in neutral....could it be a vacuum or sensor issue with the reverse gear? We don't have any $$ to take it to a mechanic... All help would be TREMENDOUSLY appreciated! Oh - and the tranny fluid was just about bone dry so we refilled it with a couple of quarts and still nothing.

Hi, I have the exact same vehicle, with the with the exact same symptoms
and exact same problem. The overdrive light is on all the time and it takes off
in high when in drive. . This means that line pressure from the pump
is reaching the High or direct clutch and the intermediate band, applying both
and putting the transmission in high gear before you even take off.
I did the same as you did and disconnected all the electrical wires on
the transmission, transfer case and overdrive. Light stays on and still takes
off in high gear. So I am thinking that the trouble is inside the transmission.
My guess: governor solenoid always open, or valve body problem
Hope somebody somewhere has the answer. Cheers Gerry

About a month ago I purchased a 94 Jeep Cherokee 4x4 country edition. A few days later I started having some issues. After the jeep is warmed up and I turn it off. If I restart the jeep while It's still warm and put it in reverse it'll die almost always. Sometimes takes a dozen times before it will stay running. Also, lately when I'm driving down the road if I hit a bump or sometimes just go up a hill the jeep will feel like its jerking back. I took it to a mechanic and he promised me it was the idle air control. So he replaced it and I picked it up a few days after he had it and 300 dollars later. And same problem later that day after I picked it up. I took it back to the mechanic and now he says I need the transmission rebuilt and the transmission is causing both above problems. This jeep has 134,000 miles and is the 4.0 inline 6. The jeep doesnt rev up between gears or anything. Has anyone else had this problem?? I also thought it could have been the crank shaft position sensor but the mechanic swears it isn't but would be happy to change that part for another 200 dollars if I'd like. What should I do? I'm pretty sure this mechanic sucks and I'm going for a 2nd opinion but just seeing if anyone else has had this possible "transmission" issue.

I just bought a Cherokee for cheap with a trans problem. I have not really gotten into it yet but meanings how this is my first jeep i wanted to ask some advice. During acceleration it does not want to upshift. You press the accelerator down a little ways and you go just fine but when you would think the trans would shift the rpms just climb. you can trick it into shifting when you play with the rpms. get it above 3k and take your foot from the accelerator until the rpms drop blow 1.5k and then put your foot back into it. other than that i am happy with it so far. Any ideas what it might be?

You don't say what year your jeep is or what model.
The mid '90s Grand Cherokee can get shifting problems related to the governor solenoid and input sensor. (Also the TPS-Throttle Position Sensor).
Here is an article about the solenoid on the 4.0L mid '90s Grand Cherokee.

You don't mention what year Cherokee it is so I'm not sure what transmission you have in it. I have a 98 Cherokee that had a similar problem. Taking off in 1st was fine but after that it would rev up like it was in neutral. Sometimes "dancing" on the pedal would get me through to the next gear. Finally I found out the plug end of the wire harness that plugs into the Throttle Position Sensor (TPS) had loose prongs so it wasn't making a good connection. At first I thought it was the TPS itself but later found out it was the plug. I would check to make sure your TPS is okay first, then if that checks out OK, wiggle the wire harness around it to see if that makes the engine idle up or down suggesting a bad connection somewhere.

Buy a new solenoid kit, filters and seals, drain the gearbox pan and change the solenoids. (you may need to flush burned oil residues). Seal well (the pan is too flexible and difficult to seal with just a gasket) and refill with light gearbox oil. Providing no electrical wiring problem it should do the trick.
#834 of 1101 06 Grand Cherokee Overland Trans problem
Jul 07, 2011 (7:27 pm)
im working on an 2006 Jeep Grand Cherokee Overland with a 5.7 Hemi. Here is my problem: when moving the shifter lever from reverse to neutral or neutral to reverse it makes a clunk sound BUT it drives normal in all gears. I was told it was the shift lever asembly module. this module can be replaced by itself or as a whole unit when replacing the shift lever assembly. i have replaced the entire shift lever assembly and it still makes the clunk when moving into neutral from reverses and vice versa. I was told also to have it reflashed or programed and Perkins DODGE/JEEP say they cant do it. What is the problem and what is the fix ANYBODY?????
