OD off prevents the transmission from shifting to the highest gear, which is overdrive. Tow/Haul changes the shift schedule so that it shifts to a higher gear at a higher RPM than in the normal mode. This helps move the heavier load. Also, the Tow/Haul will automatically downshift to help with engine braking.
Can you turn overdrive off while driving?
