we need to know a couple more things here to help you out.

like
1. does the light on the gear shift lever come on indicating that its in tow/haul mode?
2. does the CEL come on?
3. is the truck still going into overdrive?

some of the techs might want some more info but these are things that I know can help solve the problem.

Welcome to the site. For starters the 6.0 trans will go into overdrive with the tow haul button pressed. You cant disable OD that way. What tow haul does on the 6.0 is change shift points, increase line pressure, and keep the converter locked longer. If the tow haul light isnt coming on you need to have codes pulled
