I bought Honda ATF to use in my M6 after hearing how good the tranny shifts with it. I just wanted to get some final opinions from people who use it because I had always used syncromesh.

 

I have never used Honda atf, but royal purple makes a really good synthetic manual tranny fluid for trannys that call for atf. I noticed a big difference when I switched from conventional atf to the royal purple.

 

A lot of people say that the Honda ATF works great. The last time I did it I used the Mobil 1 and that seemed to work good too. I think most have good luck with the Honda or the Mobil.
