redline 75w or 80w, that's what most performance companies recomend.

Waaaaaiiit!

You better double check that. I believe most T5's take Auto Tranny Fluid, NOT gear oil.

ya the newer stangs use synthetic ATF in the manual gearboxes. i would be inclined to use mobil 1 or redline ATF.

You need a Dextron/Mercon ATF for a T-5. Hypoid wont do it. I used Royal Purple in my T-5, but I think any brand of the right ATF will do.

Hold on now, do you have a T-5 or a Tremec 3550? A "Tremec" needs GM Synchromesh fluid.....

My tremec works great with Royal Purple in it. It is an awesome fluid, made it feel like a new tranny!

ok srry to have hijaked the thread, but know i'm confused i though all the "knew" t-5 style transmissions were "tremec" t-3550's or 4550 and the old fox body had a true t-5 and tremec made a stronger version for the cobra. i'm tired, i think i jsut stripped my gears...

You're right, all T-5s, T-45s, 3550s, 3650s, and TKOs are made by Tremec. I think Borg Warner's transmission division was sold/acquired by Tremec.

A T-5 is a stock Mustang unit. A "World Class" is a slightly stronger and depending on who you talk to, either came in '89 and later 5.0s, early '90s and later 5.0s, or only in the '93 Cobras. When someone refers to their transmission as a "Tremec" or "TKO", it means they have one of the much stronger, larger, and heavier aftermarket units.

tranny fluid

Royal purple makes some good stuff from what I have heard, runs cooler and doesn't break down as fast. Do I sound like one of their plugs on HPTV? There is also another company out there that makes great tranny fluid... NEO ... I haven't tried it on a T5 but have used it in a few newer imports and it works quite well.
