I was thinking about using the Mobil 1 gear oil myself before I switched to Redline MTL. After a bit of research I found out all that lovely information.
Also great info on why ATF (original U.S. MTX-75 fill  ) is absolutely piss-poor to run in a manual transmission too (I.E high failure rate if the fluid is not changed frequently - I.E. 1 year tops) Stuff like that...
You know whats funny, I remember reading that damn thread now that I look at it again. I just wasn't in the market for fluid at the time.
I guess it went through my steel sieve of a brain.
Either way, I have to locate a dealer who sells it locally or order it online, then I'll change the fluid. It shouldn't take but a few days if I have to order it.
Too bad the local AutoZone doesn't carry it.
I still wanted to see the actual references that talk about GL-5 eating up the soft metals. I mean reading a post on here is good, but better to see a solid reference.

So in other words, the Torqo fluid I bought from BAT that contains GL-5, while it might be good for the Quaife, is going to tear my gearbox up? Damn, I need to start paying more attention to these boards!! I know from the heavy truck market you need GL-5 for hypoid gear sets in rear ends, but then again, those are hardened.
Well, looks like after engine break-in, I'll be changing practically brand new tranny fluid along with the motor oil too.
I'll put holes in him!!

I ran the Torco Fluid for about 1.25 Years! I didn't have any noticeable signs of wear and my transmission didn't change any in that whole time. If the torco fluid uses a GL-5 then what does that tell me about the GL-5 fluid since in well over a year it didn't do any damage?
Ford rebuilt my tranny, and when I first finished my 3L I put Torco synthetic into it...this was in Dec 2001 that I got it running. I only changed it when I tore down my car to put the turbo in.
The shift rods were already stiff before that because I broke my shift cable under warranty and they replaced it as well.
I don't have a bottle of Torco synthetic anymore, but if someone could verify that it is a GL-5 fluid, then it will definitely cast a different view of the GL-5 thing...I have pictures that are posted in this forum of my transmission, close-ups that show there isn't anything wrong with synchros or other parts and were only taken when I redid my pistons and shift forks/LSD in May.

In speaking with Torco they state MTF & RTF meet or exceed the GL4,5,6 specification for load & pressure but are not corrosive. Synthetic manual transmission "fluid" is not gear oil, it only emulates the requirements for that application. MTF/RTF are highly recommended for manual transmission/transaxles that use ATF as standard fill. The guy I spoke with agrees that synthetic gear oil products (theirs and other brands) are generaly a better choice over ATF or synthetic ATF in most modern transaxles like the MTX75.

So THAT would explain the commonplace syncro failures on early SVT's especially when considering that he car has to be driven much harder since the powerband is moved up into the 5000-7000 RPM range vs the normal Duratec. Thats just like Ford to spec the wrong fluid that dosent lubricate properly

They only changed the original recommended fluid spec for US vehicles. (Yes screw the home crowd!)
It has always been a 75W90 synth gear oil in the European cars. (Matter of fact that's what BAT has always sold too by no coincidence!)
I'm sure Ford wanted to "appease" the majority of the buying population (I.E a bunch of worthless sheep, but that's another story!) and use an ATF based fluid to keep the shifting feel easy in all weather and their pocket book fully lined (ATF is a hell of a lot cheaper than Synth gear oil!)
Too bad it back fired with such high warranty claims which likely were caused by the asinine fluid choice!
(The typical Ford vicious circle - cut costs by making an excellent product inferior only to have 5 times as many failures )

Fluid Does Not contain GL-5. GL-5 is a rating.
A fluid can be the "equivalent" of a "specific" GL rated fluid and not be that actual fluid.
Actual GL-5 fluid does have highly corrosive pressure additives. Check out any oil website for confirmation & warnings not to use them in transmissions (Redline, AMSOil, Mobil 1, etc)
The Torco MTF (Manual Transmission Fluid) you are talking about, like Redline MTL or MT-90, is specifically made for manual transmissions and does not have those corrosive additives.
I'm sure it works just fine, but it is more expensive ($4 per qt) then either of the Redline products.
I'd recommend Redline MTL.

Yup, I'm searching for the Redline right after this!

Ok, that makes me feel a lot better. Thanks Demon! I'll stick with the Torqo for now and when I change it next spring, I'll check for Redline.
I'll put holes in him!!

Another interesting note is that if you complain enough to the ford dealer about shift quality in your newer MTX75 equipped car(Focus)they will drain and fill with someting in a ford bottle very similar to mobil 1 or torco MTL (Ford surely doesn't make) at 25.00 a quart.
