    I did notice that if I'm driving in town or under 55 seems to give me all 4 gears. Over 55 locks back to 3rd until restart

    Thanks I've had issues both speed sensor pigtails were bare wires replaced those and speed sensors. replaced ignition switch per low voltage helped for a minute. od works for along time unless I get over 55mph. 99% sure something electrical is the issue
