2011 transmission ratios
 
I know I saw these posted but haven't been able to locate. Does anyone have them or know where to view? All I've found is Ecoboost has higher 6th ratio than the others but I'd like to see the rest.

My understanding is the the transmission is the 'same' as the 09-10, with the exception of the manual shift.

Here are the ratios for the 09-10:

1st: 4.17:1
2nd: 2.34:1
3rd: 1.52:1
4th: 1.14:1
5th: .86:1
6th: .69:1

As I recall, the 3.5L gets a taller 6th gear ratio of .61:1

Thanks, guys, that's what I needed.

According to the 2011 Factory service manual, all 11's have the same gears.

I'd seen the .61 ratio before & finally found some info after searching, here's the quote, (it's .69 for all the others):

Transmission
  • The F-150 EcoBoost has six forward gears and one reverse gear. The high ratios of the first gear and reverse gear give this little truck a lot of pulling power, and the low ratios of the fifth and sixth gears make for great fuel economy on the highway at high speeds. The first gear ratio is 4.17 to 1, the second gear ratio is 2.34 to 1, the third gear ratio is 1.52 to 1, the fourth gear ratio is 1.14 to 1, the fifth gear ratio is 0.86 to 1, the sixth gear ratio is 0.61 to 1 and the reverse gear ratio is 3.40 to 1. The 6R30 automatic transmission has a toggle switch that lets you change to manual gear changing.
