Hello I have a 87' Jeep Grand Wagoneer 360 w/727 transmission. My problem started after I had the Jeep towed home with a dolly and not a flat bed and the transfer case was not in neutral. Now when I put the Jeep in gear the transmission engages but does not move, but when I put the transfer case in low gear she moves without a problem. Please help I love my Jeep.
