Automatic problem?
 
Just purchased an '01 TJ yesterday. Have had several jeeps over the years but with the exception of a '96 Cherokee, this is my first automatic. It shifts fine 1st to 2nd & pulls strong, but have to let up on throttle to get it to shift 2nd to 3rd. After shifting to 3rd it will often downshift to 2nd if you accelerate even the least bit & to get to go back to 3rd you have to let up again. Made for a not to fun ride on the interstate bringing the jeep home. Any ideas on what I'm looking at having to do to fix the issue? Rebuild, shift solenoid, or adjust TV cable/linkage?

I would start with adjusting the tv cable first, takes like 10secs and doesn't cost anything

Adjusted the cable, doesn't look anything like the one shown in my Haynes manual (which shows linkage & cable). Seemed like it might have helped, going to drive it a couple days to see if problem reoccurs. Thanks for the reply.

Mine does this all the time at around 45-50 mph. It has to do with the crap shift points in the wrangler transmission (at least on mine).

Drives me nuts and makes me feel like I'm going to blow out the transmission. The only way I've found to get around this is by driving around with the O/D switch flipped any time I'm not on the freeway.

Although, it sounds like yours may be worse - even though mine is definitely noticeable and frustrating - I would check the other things listed as well.

I have a 5speed in my TJ , But my on my XJ adjusting the cable made a huge difference in how it shifted on the hiway, almost felt like I had more power, and the shift points felt right on

Where is this cable to adjust and how difficult is it?

Runs next to your throttle cable, there's videos on you tube that show how to do it, literally takes like 10secs

Sounds like what my 3 speed auto TJ was doing when I was running stock diff gears (3.07s) and 33" tires.
Jeep struggled on the highway - with a headwind or hill, transmission would often kick down.

If you are running larger tires, regearing the diffs or getting smaller tires could be the answer.

The cable adjusting seems to have done the trick, thanks for everyone's help & suggestions.

Glad to hear it worked out , always good when it's a simple fix

Whats the steps to take in adjusting the TV cable? Just in case I have issues in the future..heh

Adjusting mine was simple, manual showed some linkage at the transmission, but once I got the vehicle on the lift all I found no linkage to adjust. But there is a cable running to the throttle body. I simply removed a clip from that & pushed the cable jacket in towards the link point & reinstalled the clip, thus loosening the cable a tiny bit, which appears to have been enough to stop the constant downshifting.
