My trans recently blew 5th and 6th gears (for the second time). So now I am going to get a slightly used M6 from a reputable local shop. I just want to find out the year and possibly model of F-body it came from. Where can I find this info?? I've seen where it is on A4's, but not on the M6's. Anyone with an answer please help me out..

There should be some stampings on the LH, lower, middle side of the tranny.
