I have a 1997 TJ SE with the 2.5 104k miles ( I will update my profile)
with the auto transmission. I believe although I haven't looked closely that it's the 30RH 3 speed. Keep in mind I had a transmission service two years ago with a filter and fluid change and adjusted by a long time Jeep transmission guy. It had been working fine for the past couple years.
I just did a tune up on this including oil change with filter, Air filter, Distributor cap, rotor and plugs and wires. I used the Crown tune up kit that you can get anywhere.
Anyways, I never had this problem prior to the tune up, but now when I run the Jeep, usually at a steady cruise, with fairly no load around 1800-2000 RPM (40 MPH) it seems to "Hunt" for a gear. Quickly downshifting for less that 1 sec, then back to OD, sometimes several times within a 10 sec span. I only had this happen a couple of times at higher cruise and a few at a very slow going through a parking lot type speed. (Hope I described this OK)
The only thing I can think of is that when I changed the Distributor cap, I may have "pulled" the kickdown cable out of adjustment when I was changin it. (I replaced the cap while keeping the old one with wires intact so I wouldn't mis install the right wires. And in doing so may have wedged it between the dipstick and TV cable.)
I read the TV cable adjustment procedure and pulled the throttle body cover off to access the "button" on the TV cable, but I sure don't see where you could press any button to release it and do what they suggest. Just a white flat maybe square clip holding the cable in place. So rather than break something ( I have a tendency to break things)
I put the cover back on and let it sit in the garage.
I also have been reading about the possibility of a bad TPS that could be causing the problem. Although I just changed it a few years ago (5-8k miles ago maybe) So even though I read about them failing all the time I am skeptical. It's a summer beach jeep so I obviously don't put too many miles on it.
Has anybody got any ideas or experiences with something similar? I plan on running it up to the local Trans shop to have them look, but if it's something easy and common, maybe I'll do it myself. I don't generally mess with transmissions.
Thanks for input.
