What auto trans came in a 1974 slant 6 Dart?

I've searched and can't to find the model number. Seems like the most basic possible question to find an answer to.

I bet these part numbers (on the pan rail) were in it.
First is 74, second is 73.
3681841 3681061 198/225 904 Std. (Al. Carrier)

Thank you! I'm hoping to have it running today and pressure wash everything to be able to see the numbers.
