Hmm....Also keep in mind that when using tow/haul mode it locks out top gear. On my '16 with the 6 speed it will only shift up to 5th gear when in tow/haul mode. The same thing on the '19-newer trucks with the 8 speed, as it locks out 8th gear and will only run in 7th. The reason is that the top gear is usually really tall and only capable of keeping an empty truck at speed (or lightly loaded). If pulling a moderate size trailer and not running in tow/haul there is a good chance the trans will rarely, if ever, shift into the top gear. When people say the trans does not downshift as much when in tow/haul mode......that's the reason why. It's already running in a lower gear.
My 2500 and previous 1500 will shift into 6th once enough rpms have been reached in 5th even if in tow haul. The only difference I've noticed is that it does it less frequently and you pretty much have to be on the interstate on flat ground before it will even think about it.
