Joe,
I am disappointed; I was quite exited by the idea that I could get my hands on a complete valve body.
I cannot see any other way of finding out what is wrong with mine apart from doing a side by side comparison between two parts with exactly the same number. The german workshop manual does not give specifications, and findig someone with a test rig in europe will be impossible.
The only thing that is on offer over here, in France, is a complete box (without history @ 2,500$!) as I have already paid a transmission "expert" 4000$ to rebuild my box and it is all starting to be "silly money".
I guess I will have to live with the fault even if it spoils the pleasure of driving an otherwise nice car.
Regards, Coops
