did'nt read the entire post but if your trans is getin hot enough to throw A warning(not just by the gauge) and your not towing you have an issue. New trucks should handle any environment without issue when left stock. Adding A supercharger will not affect trans temp unless you really work it up A steep grade with A lot of added weight as any H-2 will drop to 3rd and no tcc lock up while climbing A long grade. If you are towing and remove the trailer your trans shift adapts take A little while to adapt but should still not cause A heat concern. Have it checked out while under warranty even if it costs A few bucks, at least they have your concern on record if it fails 10k miles out of warranty.
