What controls the tranny?

[87BuickMan]

I need to know what controls the tranny on a 87 GN. If I were to put a different engine in my GN would the tranny still work like it should? Is it controled by the computer(ECM)? What kind of problems if any would I run into.

Govenor controls WOT shifts, and the TV cable has something to do with adjusting shift point/firmness. Nothing from the ECM other than the P-R-N switch which I believe has something to do with fueling.

the problems associated with no or incorrect ecm are no lockup .it can be wired independant of the ecm however.
