2005 voyager crd Gearbox crunch ????
 

Hi all, i have just registered with the forum as i have bought a 2005 Voyager crd 2.5.
All is good except on the odd occasion when changing up to 3rd gear you get a crunch and it jumps out of gear (as you bring the clutch up), this only happens on odd occasions.
The car has a full service history (only the stamps in the book, no reciepts) and has done 99000 miles.
Any advice would be most helpful
