1. when using the towing button does this not allow the tranny to go into OD? because i saw a video of someone saying only way to keep tranny when towing is to manual shift it to 5th.
2. i under stand that extra power can hurt the stock tranny but whats the difference when your towing something heavy, aint that straining the tranny the same way?
3. after tuning your truck, how long you have to wait before you tow something like a rv..
thank you guys
