6-speed tranny gear ratios?

[shotgun]

I'm pretty darn sure I saw a post that listed the 09-10 6-speed tranny gear ratios, but I can't seem to find it...

Can anyone me out? Please?

Thanks!

From what seems to be a reputable website:

2010 F-150


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

Hope this helps.

Thank you sir!

To me, everything looks great except the ridiculous split between 4th and 5th and that unreasonably high 6th gear.....IN A TRUCK.

You can definitely feel it when you're on the interstate on-ramp, especially when you couple it with the throttle lag.

As soon as the SCT or Edge is ready for the 09-10s...

I'm pretty sure this is how they're trying to squeeze every last MPG out of the 5.4L.

So my question is in reference to adding 35" tires to the truck.

I know in the 2004-2008 trucks with the 4 speed transmission, 35" tires and 4.56 gearing was pretty much the standard and perfect combination to make up for the power loss and to preserve the transmission.

With the current 2009+ trucks with the 6 speed transmission, what would be the equivalent? I've got a 2009 Platinum sitting on 35's...have been for a year. Should I be concerned about hurting the transmission or it dying prematurely on me? I have been toying the idea around of regearing, even after I pick up the new Gryphon CS or CTS, but I'm not quite sure on:

1) if it's needed to save the transmission
2) which gear ratio would be suitable with the 6 speed transmission.


Thanks!
