I have a question for the transmission experts - I thought I knew 904 Torqueflites pretty well, I have owned several slant 6 cars with them and even rebuilt the one on my 1960 Valiant back in the early 1990s. I bought a filter and gasket kit to service mine on my 1965 Barracuda with 273 V8. The new one had two holes - one feed, one return? - and was smaller than the old filter which only had one hole. I looked at the valve body and there is two holes in it so I went ahead and installed the new filter. I was not aware there were two styles, anyone have any information on this?
 
I just looked up 67 dart automatic and the kits seem to have only one filter that looks like the one pictured, but comes with a ,904 and a 727 gasket.

The image shows both sides of the same filter.

1965 (and earlier) had front and rear pumps. 1966 the rear was done away with.
If you had a dead battery (Pre1966) You could drift start cars with the rear pump.
