I have a 93 zj and it won't down****. Going up hills it will go to downshift but go right back to the higher gear. It feels like a gear slipping either in the rear diff, transfer case, or transmissing. Other then that it runs fine. Over 216k miles and motor and trans is fine other then this problem. I haven't tried adjusting the TV cable yet but if any other suggestions I would greatly appreciate it. Thank u.

 

I'm on my phone auto correct misspelled a lot of thing. Sorry.
