I have the same Jeep, same year and I recently changed mine at 38k. I wasn't sure it had ever been done because it was shifting a little rough. After much searching on here, I decided to go with Royal Purple Synchromax. I'm glad I did because it made a noticeable difference. Now, I can't say whether that is because of the brand or just the fact that it is fresh, but in any case, it's better and I'm happy. I'm not a Royal Purple freak or anything like that.

If I had to pick one transition in mine that is rough, it's from 2nd into 3rd. It's not terrible, but definitely noticeable. 1st to 2nd is fine.
