You can use any motor that doesn't have friction modifiers in it.... Good luck finding some though!
I recommend ATF (type F if you please). It's lightly colored red so you can see contamination, has high temperature and high shear strength additives, but most importantly no FRICTION MODIFIERS. It's designed from the ground up to work with wet clutches (what are automatic transmissions afterall, than wet clutch packs and a control valve body to work them!?) and can handle the heat and beating a blaster transmission can dole out.
I'm going to be running it in my dragger.... Tell you after that expedition how it works!
