1st = 3.09:1
2nd = 2.20:1
3rd = 1.54:1
4th = 1.09:1
5th = 1.00:1
6th = 0.71:1

The transmission only uses 5 gears at a time depending on engine temperature.

Cold Engine Temps = 1,2,3,4,6
Warm Engine Temps = 1,2,3,5,6

Blackht620, I want to thank you for the info also as wayback in Feb. 04 when I was ordering my F350-CC-DRW-6.0 one of the Ford tech types told me it was a 6 speed. When I passed that info along everyone said I was full of it. I had also mentioned this in these forums in the spring of 04 & a few said I was wrong.

Now I can tell my "Chevy Loving" buddies they can put it where the sun doesn't shine.

Thanks again!

The pattern is the same it tow/haul. The shifts are at a high speed, but all the same gears are there. It will go into 6th, but at a higher speed than it will with the tow/haul off.

Shift pattern is the same in Tow Haul and yes it will shift into 6th. The Tow Haul mode holds each gear longer in both upshift & downshift. Can lock the TC in all gears to allow for engine braking and help transmission to run cooler.
