1. Adjust the throttle body pressure cable: http://naxja.org/forum/showthread.php?t=1015963
2. Test the TPS, replace if out of specs.

Thanks Joe,
I do not own this jeep, just thinking of buying it. Actually I think its a torque converter lock up issue. I will know more after I drive it. Been reading some of your tranny issue posts and it doesn't seem like a show stopper.......will post results..

Very well may be.
Next step after the cable/TPS would be to unplug the TCU and shift it manually. That will determine if any problems are hydraulic/mechanical or electric.

I'm betting TPS sensor myself. Still solenoids aren't all that expensive. Don't suppose you have a vehicle you could borrow a TPS from? It literally only takes a few minutes to replace. Even less to check with a meter.
A sneaky guy might try to chew the owner down on the price with a line about not knowing if the tranny needs rebuilt. Or he could just offer to split the cost of a TPS sensor with the owner to see if that's the problem.

I have an extra TPS so no problem....since the FSM says that both the number 1 and 2 solenoids are in the off position to shift into 4th gear, I don't believe that it is a solenoid...I'm thinking TPS.

Please let us know if the different TPS resolves this.
