I've had my wrangler for about two and a half years now, and its manual trans isn't doing too well. It's always had a tendency to occasionally pop out of reverse and it's always had this little catch when shifting into second gear, but now it's just awful. Sometimes at a stoplight, I have to manhandle the thing just to get it into first, it grinds every time on second, and it pops out of reverse every single time I have to drive the damn thing backwards. It's got about 75,000 miles and hasn't been too badly abused (at least while I've owned it). I'm getting the trans fluid replaced this week, does it sound like I'm gonna have to get this thing rebuilt? If so, how much do y'all think it'll cost me?
