Decode This C-6

[SLEEPER447]

I have picked up a C-6 tranny from a friend who doesnt need it. Was going to use it to replace the one in his truck which is connected to a 351. The tranny came out of an early model mustang w/ a 302. He kept his tranny and swapped his 351 for the 302 so I know the bell housings are the same. The numbers cast into the side are D2AP 7006AA. Can anybody help me out with any info on this.? thanks

It's a 1972 tranny.

this a good tranny for a perf. rebuild. Anything else that you can tell me about it?
It has an aluminum bell housing for a 302 adaptation.
