Hello all. I am going to be swapping out the clutch in my 02 Mustang GT here in a weekend or two (throwout bearing started squealin' like a pig). I figured that while I had it out, I may as well swap the fluid in the tranny. I doubt that it has ever been changed, and it is very notchy. I have probably spent a good 3 or 4 hours reading threads all over the internet about this particular transmission. I am still confused. Do I put in ATF, if so, Dex III? synthetic, or non-syn? Synchromesh? If so, Pennzoil, GM, Amsoil, RP? I've read all sorts of conflicting reports. I tried today to contact Tremec and see what they recommend, but I couldn't get anyone to answer. What have you had good luck with, or if you've talked to Tremec, what do they recommend? Thanks in advance for your help!
