Truck was running fine with no trans problems then I decided to show my son how the shifter worked for low range! Drove around the block in high. Stopped truck selected low drove a block or so, then stopped and shifted back to high. NOW Message window says select neutral constantly. Transfer case is stuck in low range. Tried turning off, running selector thru gate dozens of time in all combinations and all I get is select neutral and L plus gear number in message window High never appears. Can you manually select high range somehow by overiding taking out the motor? I dont care if I ever go to low range ever again.
