On a side note, what lubrication can I use to protect it well?
Specifically, I used ATF initially because it was what the manufacturer
called for but the noise was very high from day one so tried other
fluids. I had good luck with Redline MTL and I wanted to make sure that
this fluid was good for protecting the differential. It is recommended
by Redline for my type of transmission but I wanted to be sure as I read
a rumor that MTL would cause oxidation of the metal on the differential.
If you can confirm or deny that Redline MTL will help/harm the diff I
would appreciate it. If you aren't aware of the specs on MTL you can
review the specs from Redlines website at www.redlineoil.com under tech.
If there is any other lubricant that you feel is better then please let
me know.

Thanks,
Tom

Glad to see everything is working well!

***section regarding personal information omitted***

The T-2 unit is designed to run in just about anything so the manufacturer's
suggested ATF is what I would have told you to run with as we do for all
requests regarding axle or transmission fluids for the Torsen. We do get
emails from vehicle owners saying that they run their Torsen units in a wide
variety of fluids and I have not heard anything back that has been negative,
especially with the Redline MTL. That does not mean however that oxidation
does not occur, just that we have not heard about it!

Unfortunately, because of legal issues we cannot suggest a lubricant for
your transmission since we don't have the technical background to make such
suggestions or claims. I realize that this does not help much but I hope
you can at least appreciate the difficulty we face in suggesting one brand
over another and the technical expertise required to do so!

I want to highlight the fact that he specifically points out that he has had no negative reports, especially about Redline Oil.
If my diff were oxidizing and not getting lubrication because of a fluid I used I would report it to Torsen so that they would verify and have a warning to protect customers and themselves from future warranty issues.

Upon further contact with Redline, they have pointed out that there is just no way to know all the contributing factors in these situations so far posted here. They have NOT said that anyone's opinion is right or wrong. They have only taken the stand that their product will not cause the oxidation and sludge buildup reported and that it will provide superior shifting and protect the components.




And I'm guessing they haven't had any reports on MTX-75's due to the fact there aren't but a handful of people running it. What do you think they are going to say. Yea our fluids do oxidize certain metals. He states to run what the manf. says. Very smart guy. I'd do the same... oh wait I do. Our spec is Honey now not ATF but you get the point. Run what the manf. states. Then you can argue but I have an LSD in it now. Yea what does Ford recommend for those in Europe the come from the factory with them. THE SAME THING!




Sorry Todd, but you have to READ what I wrote before posting a response. Look at what I highlighted in your response and tell me how that makes sense? This was from TORSEN, not Redline. They have nothing to gain by helping or hurting Redline Oil. They would likely report any case of any problem with Redline Oils used with their differentials for ANY transmission because of the questions that I asked.
Therefore they have indirectly supported that Redline Oils are not causing problems with their diffs. End of story.
