Gearbox problems - 2004 147 JTD 16V M-Jet
Looking for a bit of advice.
A couple of days ago I got into the car after it was parked for a while and couldn't get into reverse. Moved forward a bit in 1st and then it went into reverse OK. It's happened a few times now but always after it has been standing for a while and if you move forwards it goes into reverse fine afterwards. I just reversed up the road accellerating quite hard and it jumped out of gear. Tried it again and did the same thing I'm going to take it to the garage tomorrow but wondered if anyone had a similar experience or an idea of what it might be and whether I should still drive it etc.
Thanks in advance
