'06 Acura TL - Drain and fill of the transmission, 3.5 quarts total. 2 quarts of Redline lightweight Racing (Type F) and1.5 quarts of Redline D4 (Dex III). Along with replacing the pressure switches every 2 years this transmission has been great to 142,000 miles and shifts like new. I've been using a DexIII and/or Type F since it had 20,000 miles on it. This transmission must have a fairly thin fluid, especially upon startup. Even though it's hot where I live, I can easily get away with the thin racing fluid because I have a large cooler and it rarely hits 170F. With the normal viscosity fluid, the TCC would barely drag but it did drag when cold/cool which is probably the culprit in all of the converter clutch failures I've seen.
Powersteering - Just did a drain and fill of Redline High Temp ATF. Steering feel is more consistent year round. Ive used the Redline ATF in it for almost 50,000 miles and before that was Amsoil PSF which is a little too thin now.
