I use Dextron/Mercon ATF. I have a stock T-5 which is the same as the WC, with weaker parts. Syncromesh is for Tremecs.

that redline stuff you have wont work and could cause damage to your tranny if you decided to run it. in my old t-5z (now have tko) i ran redline D4 which is designed for the t-5 and simliar trannies that like super slippery lubricants. my shifting action improved when switching from plain jane atf to the redline. i also hear good things about royal purpal or amsoil aft fluids. basicly anything synthetic will be good insurance and provide longer fluid change intervals. everyone have had different ecperiences when switching and for the most part the reponse is positive. good luck~

If you tranny is stock, it is a WC tranny, but that's just a side note.

I think synthetics are the way to go, and I've heard of Synchromesh being used in T5s ok before. The Tremecs actually specify Synchromesh or ATF themselves.

I think I might try Synchromesh with my next T5, but definitely something like Mobil-1 would be fine.

gear oil is only for the non-WC t-5's

WC actually refers to the synchro and bearing style of the trans. Has nothing to do with the load rating. Every V8 Mustang trans from 85.5 up is a World Class style T-5

Royal Purple is the way to go. It provides superior protection from everything I have seen and read. Just remember synthetic = good.

Any quality ATF that meets the Mercon/Dextron standard; if the car gets cold in the winter, a synthetic will move things more easily and warm up a bit more quickly. I use Amsoil synth. ATF in mine and in my wife's BMW. Seems to work just fine.

I'd also recommend running Redline D4. It definately helped the shifting qualities of my T-5 equipped 65 Stang.

Perhaps its too late, but Ford actually recommends for the world class t-5 in the 93 cobras that you use synthetic mercon/dextron III but its almost $18 a quart
