sounds like a buzzzzzzzzzzzzzzzzz at around 2000rpm
does it in all range positions.
its like a tiny something or another is buzzing round inside the trans.
TV-cable?

car runs fine, shifts fine.
I did manage to break my cruise control again so I will be in the market for a new cable clip at the governor diaphram inside the driver fender.
I never had the clip break, but I did have the piston break twice.
