2003 GT unfortunatly did not come with an owners manual

according to my system, you need DEXRON III ATF Fluid (XT-2-2QDX or equivalent) for the T-56 or MERCON multipurpose ATF fluid (XT-2-QDX or equivalent) for the T50D or TR3650.

3.2 Quarts so you know, I suggest Mobil 1 fully synthetic ATF or you can go with the Royal Purple ATF.

I already know people are going to say you can't use synthetic, but you can Tremec does not "FORBID" it like some will say.
