Pretty sure the 2010 3.0L uses the American made 6F35 tranny while the 3.5L continues to use the Aisin tranny in the Fusion, Milan and MKZ.
 
Why wouldn't the Ford 6F50 from the Taurus/Flex/Edge be used in them? Cheaper to ship the Aisin to Mexico maybe?

The 2.5 and 3.0L engines get the 6F35 while the 6F50 is reserved for the 3.5L models (difference is torque capacity).
 
Not sure why they continue to use the Aisin tranny in the 3.5L Fusion and MKZ. It's either a supply issue or some packaging issue where the aisin is smaller.

Gearing, the 3.5 puts out more power than either the 3.0 and the I4. Its also more sport tuned than the 6F35. Its reserved for use only in the Sport model, which I own and love. The shifts are manualesk in how it shifts, it has a slight pause between gears as if I were driving a stick, under light load, but put the pedal into it and the shifts are crisp and firm but not harsh. The ratios are setup for this car and with the 3.0 would be too high for the power output.
 
My fuel economy so far with 1700 miles is 24 city/highway mix, and 31 highway. The 3.5 and 3.0 get basically the same eco numbers.

But they use the 6F35 with the 3.5L in the Edge, MKX, Taurus, MKS, Flex and MKT. But they don't use it in the Fusion/MKZ. Has to be more than just gearing.

The 6F50 is used in the Flex and MKT. Not sure about the others but I'm pretty sure anything with the 3.5L uses it too save for the Fusion apparently. The 6F35 is reserved for those engines smaller than the 3.5L. My question stemmed from this. Packaging issues or shipping issues are the only two reasons I can think of for Ford to use the Aisin in the Fusion Sport. I can't imagine it would be packaging though because the 6F35 and 6F50 are supposedly the same size and the 6F35 is used in the non-Sport Fusions.

Yes, the 6F50 is used in the 3.5L applications, not the 6F35. The 6F55 is the beefed up version in the ecoboost models.
 
The 6F35 and 6F50 may be the same size - but the 3.0L and 3.5L engines are not. It's possible the 3.0L + 6F35 would fit but the 3.5L + 6F50 would not. It's just speculation. Maybe since they used the Aisin 6 speed with the 3.5L in the MkZ before the 6F50 was available it was easier to keep using it instead of switching.

That makes sense too Allen. I was thinking it might be cheaper to ship the Aisin from Japan to Mexico (via boat) than it is to truck or train-then-truck the 6F50 down there. Then again, your packaging argument makes more sense given that they already do train-then-truck the 6F35 down there. Although I'm not sure where all the variations of the 6F are assembled either.

Frankly, the reason could be anything - taxes, shipping, plant capacity, purchase agreements. But isn't it fun to speculate? I'll see if my Ford contact has any other insight.

as an fyi, multiply the number after the 'F' by the number of cylinders to get the transmission torque capacity.
