i was just wondering if the Tow/haul button was the same thing as the overdrive button on the older models.

The best I can figure out it's also different shift points, lock up points, and shift delays. In short, it's a completely different shifting strategy. It also provides engine brakeing.
The manual provides a lot of good information.

Good job Shotgun!
Ford has copied GM on this one. GM has been running a set up like this since 2003. At least they have on the HD gassers.

Even a blind squirrel finds a nut once in a while.

Holy Cow! What a great modification! Makes me ALMOST want to run right out and get a new truck! Then I think of the payments and....
![]() But, it's clearly NOT the same thing as the overdrive button. That only locked out 4th gear. As far as I can tell, nothing else changed. They could have easily set the A/F ratio a bit richer too, as long as they stayed within EPA guidelines. And, shotgun, super research! Good on you! - Jack

Based on my towing experience, yes it is. When I'm towing my 4000 lb boat on level roads, I have seen the same RPMs (around 1800 at 65 mph) as when I'm not towing. However, it does take longer on a flat road (with steady throttle position) to get to OD and it doesn't take much additional throttle to get it to drop out. Note that I do have a 3.73 LS rear end.

Alls it boils down to is different shift strategies and torque management that are both electronically controlled. |
