I have a 2000 TJ with 91k miles and just with in the last week or so Iv noticed the shifting had gotten pretty rough. First gear is really no issue but second gear feels gritty like it wants to get hung up. Third gear is the same way and forth is too. Nothing feels smooth anymore. Iv only had the Jeep a for a month and the thing drove very smooth until now. I’m not hard on it either. Plenty of pressure on the clutch pedal too.
