Just recently when driving my gearbox keep popping out of drive and going into limp and i have to nudge the gearstick to then find the drive gear. Has anyone else had this before? Mitsubishi garage are quoting me a huge amount of money to strip down the gearbox to investigate and even then they say they would may not able to find the problem and fix it.

can anyone help me who have had this issue before.

Its an L200 animal 08 plate
