As soon as I take the pressure off the accelerator when the van is in 5th gear, the gear stick pops out into neutral. Any thoughts from anyone before I take it to the garage?
usually when it jumps out of gear on over run it is a sign of a worn synchro hub in the g/box,you can either put up with it or try sourcing a 2nd hand g/box.
