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!

1994 Cherokee solenoids? by genpattuck

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.

1994 Cherokee tilt by genpattuck

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.

93 JGC laredo tranny problems by dsummers1

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.

For the solenoids, you would basically do an ohms test to measure the resistance of the coil in it. This information can be obtained from the correct Transmission or vehicle service manual for your year vehicle. As I've mentioned before, these can be viewed on some websites that show these manuals. link title is one of them.

It is normal for your transmission to handle shifting differently until your transmission fluid reaches normal operating temperature.
