2020 GM/Chevy gas 6.6L max towing test

At the end of the test they were going 2600 RPM at 25 mph. Truck wouldn't downshift. I wonder what would have been different if they put it in manual. To be honest I never put mine in manual, but I have not towed the IKE.

I use manual mode in a auto tranny for that type towing. I made a living for over 11 straight years with manual transmission LDTs so I know better than the ECM which gear to select and at what point a gear shift is or isn't needed.


Of course these test are better suited to for those that don't want to do the thinking/shifting for which gear is needed at that moment.
Results would be different up and down hill using manual mode by a experienced operator........or a smarter engine/tranny operating ECM.
