I have mitsubishi 2000 challenger. It has a serious problem with shifter which indicate 2h 4h 4l. Few days ago when I was travelling through hilly areas. It went bad and stuck there. I tried hard but no way it was moving further. I tried to turn shifter into the neutral mode but it stuck. When I put it on Driving mode or reverse mode. Its doing nothing rather than going back or accelerate only it was on hilly areas or neutral Any idea whats wrong with that.
