I run Type F, but use Redline's synthetic version. I believe ATI's synthetic ATF is also Type F, FWIW.

Street use with the additional heat & slippage from a high stall converter rules out standard (non-synthetic) ATF for me. I also use an accessory trans cooler. But that's my approach and others may not agree.
