Choosing a Rebuild Kit (TF 727)

Idk if its just a typo or not but the ebay kit says its made by transparts. I wonder if their related to transtar?
also whts tge difference between an A727 and a 727? Just one is dodge and the other is chrysler maybe? I know dodge and chrysler are pretty much the same buti didnt know if maybe they each had their own part number or something.
