Dextron/Mercon III I think, or at least that's what I had in mine. I removed the power steering and I will never go back, but that's just me. As for the tranny I'm running Redline MTL, but I think I'm supposed to be running ATF. I don't care because it runs/ shifts fine, but I've heard in cold weather the shifts aren't as smooth. I don't drive my car in the winter so it doesn't matter.
