Recently I had those same symptoms on my 1998 Cherokee with the AW4 transmission. At first, on rare occasions it would slip briefly out of the blue. Then wouldn't do it again for quite a while (or days) after. It was a sporadic symptom. At first, it wasn't affecting the engine. Finally when that began to happen, the engine would run terribly as if someone pulled a spark plug wire off. Finally it got so bad at a point (I deliver mail with it), it was stalling every time I stopped at a mailbox. Also you could smell the engine was running very rich.
After scouring the web for answers, I ended up replacing the TPS and the problem went away (or so I thought). Sadly to say, after a couple of days the problem came back. It was only corrected (in my case) after I discovered the connector that plugs into the TPS had contacts that were "sprung" or weakened by the weight of the wire harness on it. I couldn't wait to order a new one, so with the help of my wife (needed four hands) we disassembled the connector and bent back the female pins so they would grab tight again. Finally the problem was solved!
Apparently, when first replacing the TPS, I moved the wires enough to make a good connection again, only to last for a few days. By wiggling the wires at the connector, I could make it go from bad to good (and vise versa).
Hope this helps!

BS, BS, and more BS. That's what you're getting from the dealer in my opinion. I had a shifting problem where when I stopped, it would not shift down to first again. If I shifted manually with the shifter, it was alright until I stopped again. I brought it to a transmission shop only to be told I needed a rebuild or new transmission. Later, I made an appointment with a dealer to scan for transmission codes and analyze it. For $100 they told me the same thing. So in my opinion, the shops out there only want to replace or rebuild your transmission because that's where the money is at.
Finally, with nothing else to lose, I pulled the pan, tested the solenoids, and found one of them bad. I bought a solenoid kit off the web (way cheaper), and my problem was fixed! No thanks to the shops.
Assuming fluid level is okay, from my experience, I would start out testing the TPS, and if that's not it, test the solenoids. I am a firm believer also, if the transmission is working fine except for misshifts, then it's a part problem and not the whole tranny.

Oct 02, 2009 (12:27 pm)
just bought jeep grand cherokee, 87000ml, had engine problem, fixed it easy, but now trans is playing. on D it would jump from 1st to 3rd, would need to rev engine quit a bit to to it. and would not go to 4th. but if i would start drive on 2, not on D, it would shift from 1st to 2nd(would still need to rev it hard to get it done) and when driving on 2nd when i change to D, it will shift nicely to 3rd and 4th. no fault codes present, had it check at few garaged and they cant tell whats wrong, they say what need to take gearbox out, look inside. and it would cost a lot.
and O/D button isn't working, o/d on all the time, but they say it's nothing to do with it. any thoughts?
thank you for your help

OH YEA! ! !.. sounds like you found the problem-bad connection in the t.p.s-contact- then fixed it!..the only thing i might add is a habit i've gotten into,and coated the contacts with -dielectric grease-..it's non conductive(won't short anything),and keeps contacts from rusting/corroding ...should be at the auto supply,in a tube,or at a electrical supply..i use it whereveri fix a connection,and especially on the trailer hitch plug !..keeps the water out..
--your tip about the pins on the connector for the throttle position control sounds like exactly the problem..glad you fixed it,and shared it with us!
#377 of 1101 1994 Cherokee solenoids?
Oct 04, 2009 (9:24 am)
Mine is an auto, 6 cyl, 4x4. When in drive, only the high gears work. I have to start in 1st/2nd then 3rd then up to drive. I was told the solenoids need to be replaced. The tranny is an AW4. Can I try to reset the computer with the negative off the battery, foot on the brake pedal, key in ignition turning on/off 3 times or do the solenoids need to be replaced? Thanks.
#378 of 1101 1994 Cherokee tilt
Oct 04, 2009 (9:49 am)
My cherokee has a factory hole in the column at the top that may have been where the tilt lever was. My cherokee is the bone stock model with reach across locks and crank windows. Could it be missing the lever or was my year/model not have this option?

If yours is anything like my 98 Cherokee with an AW4 transmission, I would start off checking the Throttle Position sensor first, then if that's okay, test the solenoids second. Both can be checked with a volt/ohms meter.
The solenoids can be tested at the wire harness plug coming from the transmission. Make sure it's the right one, and not the harness coming from the shift selector switch Other people have said it can be tested at the plug going into the TCM (Transmission Control Module) under the dash.
I believe you might be able to view the service manual at Scribd.com to assist you in making these test measurements. If you are comfortable using a volt/ohms meter, then it's fairly simple.
I've never heard any method of resetting the computer (minus the dealer "flashing" it), unless you're talking about erasing the trouble codes in it.
Hope this helps.
#380 of 1101 93 JGC laredo tranny problems
Oct 05, 2009 (11:49 am)
so im new to this forum and desperately need some help. i have a 93 jeep grand cherokee laredo 5.2L V8. I dont know much about trannys and need to know if this is worth fixing. So my jeep has 142000 on it. ok so i noticed a couple times that when i put my car in drive and try to move that sometimes the RPMS will go real high but will not move until i throw the car out of drive and manually into 1st gear. from there i have no issues taking off. if i can take off in drive it takes a real long time to get up to speed. now when i am on the highway driving around 80 the car will shift down all of a sudden even when my foot is on the gas. then finally when i hit 81 it will shift up and start to accelerate again. i dont know what to do. if i sell the car now i will take a major hit money wise. please let me know if you have any suggestion. I am in the military and live in germany so i dont have very good luck getting certain parts over here, so please let me down lightly.
