A833 gearbox 4th gear doesn't work

Sorry for not replying but it turned out quit good.

The mechanic took the trans apart and inspected everything, put the trans back together and said that he didn't find anything wrong.
I adjust the shifter stoppers (they were very loos). Now I have drven the car for 200 KM and no problems.
So it seems that the reason was overshifting.
