At 65k, maybe all that is needed is a tranny fluid change.
Where are you located? Columbus, OH, has a great mechanic who can solve that, if you are close by.
As for valve body issues, I don't know, especially if the car was well-maintained. I have 2 '06 MCSas and my daily driver has 117k on it. I had its tranny fluid changed at around 85k and it has been clear sailing ever since.
The other has 66k and I'll be getting its fluid changed before the snow flies, even though it is showing no problems.
It's a bone stock S, while mine is heavily modded and has seen lots of twisties as well as track use.
Good luck!
