My 03 silverado would shift really rough on Tow Haul mode. Buddy with the same truck noticed the same thing. Shifted hard enough to make you think it was better to leave it off for that particular truck.
Currently have an 02 7.3 and all it has is a button to ditch 4th gear. Not sure if it adjusts shifting and torque converter slippage.
The transmissions of almost 20 years ago were different animals. The 2005 Chevy I used to have acted similarly. Yes, the button in your Ford just turns off the overdrive.
