I'm not sure if Tow/Haul is a button to push, or just taking it out of overdrive when climbing/descending a step hill. 2003 Ford V-10 and all I have is the overdrive button on the shifter. Maybe newer units have this button?
The 5 speed and newer transmissions have tow-haul; the older 4 speed transmissions have overdrive off. The buttons are generally on the end of the shifter in both cases, but are labeled differently and cause different behaviors.
The overdrive off for the 4 speed transmission does exactly what it sounds like: it locks out overdrive, similar to how shifting from "D" to "2" locks out overdrive and third gear. Tow/haul, on the other hand, does not lock out any gear, but alters the programming of the transmission computer brain thingy to be more appropriate for heavy loads (by changing shift points, downshifting when braking on a hill, changing when the torque converter locks and unlocks to reduce heat, etc.).
