Regardless of what vehicle you have, I think you should only use tow/haul or OD off modes if you actually see some NEED for that......like the engine is lugging going up small hills.
I would think with an 8 speed transmission it should handle most situations without intervention.
Wrong, you should always engage TH when towing, it is what the manufacturer recommends and how the vehicle is designed. The fuel efficiency focused shift patterns of the details maps are not appropriate for towing and the extra heat generated by the torque converter when not locked under load is not good for engine or transmission. In addition at least on my vehicle the hill assist feature is pretty worthless unless in TH mode.
How can Sam be wrong when your both saying T/H should be used or did I miss read what your both saying.
