I have an all stock 87 Comanche 2 wheel drive :'( 4 liter, auto Problem is when you drive, it has power up to 30-35 than it falls on its face. I did tune up and still doe's it. A guy said it might be the shift points are off. Any help would be great.

Sounds like you're loosing compression....IF that's the case...that's NOT good.

Could it be the throttle body sensor?

Possibly

my old f150 explorer had a stupid little vacuum spring assembly on the trans and it did that same thing switched it out and it worked dont know if jeep has that or not

Hey Hillbilly,
Sorry to get off topic, but what's the deal with the F150 vacuum spring - a - majig??? Where's it located on the trans and how much of a hassle is it to swap out? My F150 upshifts so fast it feels like I dropped an anchor! Again....sorry for deviating from the subject matter!

on the side of the trans round looking has a snap spring to hold it in ask the boys at any autozone their comp should show it

Thanks Adam...I'll try it before I trash the AOD.

i have a 93 cherokee and mine was doing this as well. i replaced the tps sensor and it now shifts fine. just an idea, im not familiar with the earlier years 4.0

Thanks for all the info. We got it working. On the dash there is the power/economy switch and it works ok when you have it on the power setting. Going to try to get a new switch.
