After years of faithful service, my tranny is stuck in 2nd gear. I was parked on a slight incline, and when I got in my truck to leave, it wouldn't shift out of 2nd. The clutch is fine; in fact, I was able to limp it home---slowly---in 2nd. The top is off the tranny, but as you probably know, it has to be in NEUTRAL to remove the top of the tranny. Is there anyone out there who can tell me if it's even possible to fix this, or do I just replace the transmission? This is beat....
