Hey y'all. My 95 YJ 4 banger with ax-5 just turned 120k miles. About 200 miles ago, second gear started giving me trouble when downshifting. It had never given me any problems whatsoever, so I was a little surprised. I changed the fluid, which came out a tan murky color (must've gotten some water in it), and added 3 quarts of redline mt90 and filled the last 1/2 quart with Lucas oil stabilizer. After about 100+ miles, the shifting seems to have gotten smoother shifting through every gear, yet ONLY downshifting to second grinds. I've tried double clutching with no luck, and it seems no matter how careful I am it wants to grind going into second. It seems to point to the synchros being shot, but the sudden onset still makes me wonder. Anything I'm missing or should try? Thank you!!
