Since downloading the .17 tune, my truck will hang in 5th gear as I get on the highway every morning. It will run up to 2600 rpms and never shift, so I have to let off and feather it to finally shift to 6th. I do have the overdrive tune and running with the Tow/Haul OFF. Anyone else experience this?

Whats the trans temp when this happens?? Since you said "every morning" I'll bet the trans isn't up to temps yet. Mine will not shift into 6th until the trans is at 70* degrees or better. Once it gets to 70* everything is fine. You can moniter trans temp on the MM and also the EVIC.

yeah if your trans is stone cold, she won't shift into final overdrive...i don't know if that's a H&S feature or a Dodge feature, though...

I have the Overdrive tune as well. I noticed it with .15, .16 and .17 but I figured it was the cold tranny temp cause once warmed up it shifted fine.
