The T56 requires Dexron III ATF fluid. If you can spend the extra money, go with GM Synchromesh fluid (from the dealer) or some synthetic Dexron III fluid like Mobil 1 or K&W.

Most of the Mustang Race shops use Redline MTL in place of ATF.
I use Redline 0/20 weight synthetic motor oil in my T5
ATF is just a highly refined hydraulic fluid that is the eqivalent of straight 20 weight(viscosity)
edited to add that Royal Purple 11 is used in a friends 6 spd Vette with good results
