[thompsons]

Hi , on driving our 1967 commer camper (perkins diesel engine) along at 50mph in 4th od it sudenly made some nasty noises and felt like it had slipped out of gear, it did pick up again but i can no longer engage overdrive.
Any ideas on what may be wrong?
thanks mark

What kind of nasty noises? check oil level in gearbox.
