While driving to a buddys shop to do the brakes. I noticed my Cherokee wouldn't shift gears unless I redlined it. What could be the problem?

I'll note that the car is not legal yet and the people I bought it from had it sitting for a while. But this is the first time its done this.

 

Try adjusting the tv cable?

 

Tv cable? I'm a noob when it comes to trannys

Not to thread jack, but i have almost this same problem.

Could this cable also cause it not to shift period? With the jeep in drive it's really sluggish but once up to 40-50 it is pretty peppy. If I pull it down in 1, it takes off just fine then to 3 and drive following. Bought the jeep from my cousin and it's been setting a little over a year and he said he put a new detent cable and fluid. Is this cable the same as a detent cable?

 

your having an electronic issue, check the trans fuse on the fuse block [IIRC top right corner 7.5amp], then check under passenger side lower dash that box bolted to the lower dash is your TCU that controls the trans make sure its fully plugged in, there is also a fuse somewhere in that harness check it aswell.

when my automatic started to **** the bed i would have to pull the fuse and drive as you stated 1/2-3-D

the reason it doesnt pick up till 40-50 when your in D is cause its like your starting in overdrive

 

Is this the connector for the tcu. Found it tucked under the carpet connected to nothing but does have a fuse in the same harness

 

Ok mud dog that was it. Found where that connector was supposed to be plugged it in and works fine now. Many thanks

 

yep that would be the one, glad it worked out for ya.

 

I haven't been able to check all your suggestions yet. But could a bad transmission mount be a factor?

 

No. If you have an 87 to 90, check what was already suggested.

 

bad trans mount will just give ya the shakes, possibly lead to shorter life span for u-joints but thats bout it

 

I'm finally back. It was the tps so thanks for the help.
