I could see it being a stuck caliper. The viscous coupler, no. when the VC fails it makes it hard to turn. It has no effect on straight line driving. When it does it, do the rpms go up and it just sits there? Does it only do it from a stop, does it occur after applying the brake, etc..

 

I don't know what else to say, it happens warm cold hot, just when it feels like it....it just gives me on and off power issues! Driving me nuts!!

 

Again true. But as said with the information given and the inability to diagnose the problem our thousands of guess could be shots in the dark but i agree. With you

 

Everything seems normal otherwise, perfet! Nothing to do with turning, rpms seem always smooth, it's not in 4wd, no air, just simply goes from torque to no torque at a idle before I give it gas....DRIVING ME NUTS!!!!

 

Anyone else still thinking a bad air fuel mix? Im on that boat still.

 

Okay f this. Where are you. As in state. Lets find you someone who can physically help you. Like usmc said. These are all shots in the dark

 

I think its trans. Only way to find out is ruling everything out 1 by 1

 

Any dummy lights?

 

True bud true

 

Don't see how it could be a thousand things. RPM's are very smooth, nothing seems strange, just as it please's it gives me the power of the 5.2 otherwise it's the evil 1.8, like I said it seems to be all transmission realated, my Dad was a drag racer so I learned much from him....rip...daddy.......

 

Like i said i really think its an internal trans issue. Have you had the fluid changed, maybe a flush before this happened?

 

1 by 1 is fine, and no dummy lights....lol...

 

Like i asked, trans service? Fluid change, ANYTHING trans related before this started?

 

Danielle,
I'm no expert, and also find it hard to diagnose over a keyboard, but I'm candidly surprised at some of the fairly wild *** suggestions posted here.
I will stake my educated guess that it most definitely IS the transmission, and as noted above, makes almost all other suggestions hard to believe.

Your description of no movement regardless of rpm, yet sometimes engages is extremely characteristic of a bad VC (or on some other vehicles a torque converter) gone bad. This is a transmission problem, period.
Your tranny is most likely repairable, but if you go on Craigslist in your town, you'll find lots of parted out Cherokees or just the tranny alone quite cheap.
Also junkyards have these stacked up and even offer a short warranty. You DoNT need to go to a transmission shop and get taken to the cleaners.
Find a friend who is mechanical, or a trusted(?) small mechanic shop to swap it out. It will end up being cheaper than repairing yours in my opinion.
Best of luck! Let us know how it turns out....

 

I just had a flush done from some dude who was wanting to get more than a thank you, but still the same. I am willing to do one thing at a time, just wondering where eles I should start.....and THANKS to all the amazing peeps here trying to help
