The AM6 in our 307 HDi has lost it's smoothness and become a bit rough. The most significant problem is that on the change from 2nd to 3rd there is a delay between 2nd being released and 3rd engaged which allows the engine speed to increase resulting in a quite violent engagement of 3rd. I have changed the transmission oil twice with no improvement. It's usually OK from the start of a trip (hot or cold) but as the trip continues the problem appears, but not always. In another thread there was a suggestion that something similar was a solenoid problem. Any ideas? It has done 190,000 km.
Thanks,
