I've read the owners manual and scoured the internet but haven't really found a good definition of what using tow/haul while towing our travel trailer really accomplishes.
Maybe someone could provide me a simple explanation.
Thanks in advance!
Tow/haul mode provides delayed upshifting to the next gear to keep you in the power band a little longer & quicker downshifting for the same reason plus quicker downshifting requires less brake use when letting off the throttle while hauling. Also, torque converter lockup is quicker to prevent excess heat build-up in the tranny and the ability for trans to go into OD is more limited/or restricted because the higher gearing will make the torque converter lock and unlock too much under heavy loads.
