What tranny?

It looks like its a 727. I found a picture comparing pan seals for a 904 and 727. It looks like the 727 shape. It has a bump on the right side top and a corner rounded off on the bottom left. The 904 looks kinda square with the bottom right corner rounded off.

Heres where I found the info
