Maybe the 10 speed autos will be the bees knees, but if they are better than the 8l90 GM will use them too. The 6l80 was an average transmission as I never felt it was very responsive or fast to shift. From what I've read, the 8l90 is much better in those regards.

I'm curious if they will have the same ratios since Ford over gears them to take advantage of the high winding DOHC vs gm's wider gears for lowend/mid range grunt. Or will the trans itself be swapped by replacing bell housing and the tailshaft?
