I've got my MTX opened up and sitting on my workbench right now. I changed out the stock ATF at around 40K miles and started using the Mobil-1 cocktail, draining and refilling about every 25K miles. The transmission, now at 112K, looks absolutely spotless inside and there were only a couple TINY metal flakes on the collection magnet. Looking over the internal components, it's hard to see any indications of wear. Even at 112K on an almost 10-year old transmission, it still shifts great (i.e. no syncro problems).

I've got 3 bottles of Redline MTL ready to dump in after my Torsen/Fork install, but after reading this dialogue, I'm inclined to continue using the Mobil-1 cocktail until the 'MTX Heavyweights' duke out the MTL issue some more. In the meantime, I'll hold onto my bottles of MTL.

I agree that it's hard to blame 2 transmission failures on MTL, considering that the fluid change history was unknown. If you don't keep the fluid fresh, it's gonna come back to bite you, no matter what fluid you're using.
