I have a 91 Jeep Cherokee 5spd manual inline 6. I was driving my Jeep today and I came to a stop sign then waited for traffic to clear and tried to shift into first again but nothing (no engagement) What I ended up doing was leaving my jeep on the side of the road and tested it a little. With the engine on, the gear shifter is stuck in neutral and wont shift to any gear. Well you can shift it into reverse and it grinds. With the engine off you can move the shifter to what ever gear you want. Please help thanks!!
