Redline MTL or Royal Purple Trans Fluid

[Dark Pony]

What type of fluid does the MT82 take and where can I get either one of these? I'm sure some of you guys have swapped fluid.

[Dark Pony]

Well I answered my own question on Redline...it's 70w80 GL-4 and can be ordered direct or they have a dealer list, including Lonestar Performance, Speedtek, LG Motorsports and a few others.

I think it's 75W-90, I think.

I was looking into going full Amsoil on my next oil change. Trans fluid, engine oil, and Modul 666 clutch/brake fluid.

[DirtyD]

Well damn, you beat me.

[Dark Pony]

Yeah, I've read 70W80 in a few places now for Redline. I also read a lot of problems with Amsoil trans fluid.

What problems?

I clicked them but I'm too lazy to read all that, I drive an auto anyway... :sleepy:

Oem is decent. Also did y'all know that Ford oem brake fluid has the highest boiling point of any other manufacturer and some aftermarket lol.
What with the name brand blind loyalty these days? Just go with a full synthetic motor oil especially if your daily driving it with just a few track days. Otherwise it's a waste of cash. Your money though.

I'll have to read the AFM link later, as that's blocked here at work.

I only really saw that one guy had problems with Amsoil. Not really any other people that chimed in about it.

It's still DOT3 fluid. If the brake/clutch fluid Ford used in these cars was so great, why do so many people have issues with the clutch fluid boiling over, yet when they switch to a DOT4 or 5, there are no more problems?...

Look it up if you don't believe me. As the fluid ages and picks up moisture that boiling point changes. Fresh boiling pt is around 550f I believe. Better than some dot4.

If the oil picks up moisture over time, moisture is water, changing the balance of water to oil, and by simple chemistry, to me, that means the boiling point would be lower with more water present....

As with everything else, viscosity is also a big thing with the brake fluid. I know I'm no expert, and I intend to start reading up on these things, but the general understanding is pretty simple.

That's what I said. As it picks up water the boiling point drops. I was saying this because you spoke of some cars boiling their fluid.

Yeah, you said it would change, I was just stating that it would drop.

I will say that when I did a majority flush (didn't bleed the entire brake system) and added some DOT4 to my OE DOT3 fluid, I noticed a difference in the clutch feel immediately, and never had problem with a sloppy clutch pedal in the high RPMs.

[re-rx7]

It may be wrth it if you track but on the daily it's questionable.

[DirtyD]

I plan to start doing some autocross events, so it wouldn't hurt to get it in the car and get it flowing through, then do another flush and add to make sure it's all one fluid type.

Honestly, I haven't had any problems thus far. However, I'm going to go with Redline MTL...nothing but great reviews.
