transmission casting number

Looking for where the heck the casting number is on a 4r100. The place I'm buying the tranny from said it should T771AA or T781AA or something along those lines (don't remember exactly). Any idea where to find it? There is nothing like that on the tag rivetted on the side.

A casting number would be cast into the case. I have no idea where, or what those numbers mean that you have listed.
