Maybe it's just my truck or the conditions, don't know. But my truck has never shifted into 6th with the tow/haul button engaged...ymmv :)
I would go for the 4.10s to the other poster...it adds so much capacity and for $125 option it seems like a no brain-er in HD truck...
Does tow/haul change the shift points at all? If it does, I wonder if it is just holding on to 5th gear for higher RPM's necessary when towing, rather than shifting down to 6th. Then when you take it out of T/H mode, the shift points revert back to lower RPM's and it kicks into 6th gear. Does that make any sense?
