Thanks for you reply. I wasnt clear.

I bought a wagon from him.
He told me in a phone conversation (before he dissapeared) the he had just bought a sedan from someone else. (A sedan with a lot of miles.)
My suspicioun was that during his inexplicable absense he decided he liked the low milage tranny in the wagon I had purchased from him - and which he has not yet shipped - removed it and put it in his car.

So I was wondering if I could tell if that had been done by serial numbers - but apparently not.

Thanks for the information however.
