I spoke with Leo Capaldi this weekend about this. They started out with another type of atf... they were having gear problems with pitting and discoloration iirc. They tried a few combos and were basicly outa luck.. nothing was preventing gear trouble.

They ended up turning to Ford... Ford has been working VERY close with Leo on the mtx75. His box is built well beyond spec... even moreso then the bulldog box. Most parts have been upgraded... we're talking diffrent metals not just simple changes. Thier final choice was ford synthetic.. .now of course this is ford talking....

Look HERE

That is Leo's post in our forum. Take it for what its worth... but NOBODY abuses a mtx75 like him... remember.. he blew 18 boxes in one season......
