Oh that's right. We don't count because Terry said it's the MTL because he found it on 2 MTXs that ran MTL for a short period but had a neglected history. That's logical...



This was sort of the point I was getting at. There aren't a lot of people on here that know their car's true maintenance history, which is why I asked for people who've owned their cars since new.

I do know that my transmission has been rebuilt twice for 3rd gear grind. The first rebuild was at ~34k miles, and the Ford recommended fluid was used. The second was at 52k miles, and I've had the Mercon ATF w/ FM for 32k miles, and it's held up a lot better than with the previous fluid. Not to mention this last build has seen it's most abuse with the 3L having been built at the same time as the tranny rebuild. I think I'm going to do a tranny flush and fill this winter, but the fluid I use is undecided.
