Excellent photos! That's an early '63 T-10, originally installed in a '63 Impala built at St. Louis. The transmission was assembled on December 4, 1962 on the second shift at Borg-Warner, and the 1963-only T10-1D main case, T10-7D tailhousing, T10-148B side cover, and aluminum 3790278 front bearing retainer all appear to be original. The identical transmission was also used in Corvettes, but the VIN stamping on that one ID's it as having been used in a passenger car.

John,
What distinguishes it between an Impala and some other full size, such as a Bel Air or Biscayne?

I just used "Impala" as a generic term for a full-size car - could have been a Biscayne, Bel Air, or Impala.

OOOOOOOOOOOOOOOOOOOOK, glad to know that------------I thought maybe you had some magic method of interpreting a code that was invisible to the rest of us!

On a T-10, the only external clue to the internals is the ID tag on the side cover bolt; that one has an "AU" tag. I have images of "HH" and "CC" T-10 tags, but I don't have the magic decoder ring to tie them to a specific transmission.
