@ Funny-

Wikipedia confused me as well. My 2006 US Corolla XRS came with the C60 with a 0.725 6th gear. I looked it up online to be sure. I also re-verified with both my tachometer and scan gauge on the highway:
60mph:~2700 +/- rpm
70mph:~3150 +/- rpm

If my car had the C64 tranny- the 0.815 6th gear would yield
60mph:~3045 rpm
70mph:~3553 rpm

Since my rpms are no where near that high, I must conclude that either my tach and scangauge are way off and I have a C64 tranny- or Wikipedia is incorrect and I have a C60 tranny. Which is it? Thoughts?

If I do have a C60 tranny, then I suppose my only option is to go with a custom 6th gear in the <0.659 range.

Thanks in advance.
