Hello All,
Fall of 2022 I picked up a used LJ Auto. Previous owner(s) had made some changes. It has 35s on 17 " JK(?) wheels, body lift, metal cloak fenders, different front bumper,etc. The list goes on but for the purpose of this thread I'm thinking the 35's are the more imprtantant info. I don't know if it had been regeared and the last owner didn't know either. Anyway from day 1 it had a little bit of a funny shift to it when it went into the higher gear(s). I generally have run it mainly with the overdrive off and it has been ok until lately. It developed a shudder when it shifts up. 1st & 2nd still seem OK but after that is usually when it happens. Fluid was a little low so I topped it off with ATF+4. The issue continued and got worse over time. Last week I had the fluid and filter changed. Refilled with ATF+4 and added shudder fix/additive- that from what I have, read may or may not help. It is maybe doing a little better but still not right. I only have about 50 miles on it so far since the fluid change. I intend to give it a little time, maybe a tank of gas/couple hundred miles and see what happens. I don't wheel it. It was bought and is used for going to the beach, a little beach driving, and running around town. I would eventually like to use it for some mild trails or some portions of the Trans America Trail ( TAT) if I can get it dependable enough to make some trips like that.
I like the jeep, plan on keeping it, and bought it knowing it would need work. It is worth it to me to fix it so I started this thread to chronicle the issue and what I end up going through to resolve it. The goal being to: 1) fixing it as cost effectively as possible and learn something along the way, and 2)maybe help someone else out with a similar problem with this information and results.
As always, any info/advice/suggestions are appreciated. Pic of the jeep added so you know what I'm working with.
