Push Button Automatic

A quick question I recently bought a 1965 Dodge Town Wagon and it appears to have had a push button transmission. It now has a newer tranny in it 727. I was wondering if you could use the push button assembly on a newer 727 tranny or even a 518.
I have a 392 Hemi to install in this build and I am probly going to use a 727 so it would be kinda cool.
