Tow /haul mode questions

Hello to all! Hoping to pick some brains and get some answers.

We recently traded our 2008 f250 6.4 (nothing but issues starting) for a new 2012 f250 6.2 (gas) understandably towing and torque is different but it seems abnormal that in tow/haul mode the trans would bypass 3rd and slam into 2nd on even the slightest grade. It would then sit in 2nd often revving well over 5000 rpm even upon leveling out. We finally finished the trip manually shifting, but lost the engine braking feature in doing so. Planning on taking it to Ford but I know they won't be able to duplicate this without towing. Any thoughts/experience? Thanks!

Your symptoms are NOT NORMAL at all, I have a 2013 F250 with 6.2 and all I can say is that so far mine shifts buttery smooth, no slamming with 9K miles on the clock.

I would highly suggest that you document any odd behaviors like this with a video camera and then go to your dealer. Without some credible evidence like the video you most likely will get the dreaded "no problem found" or "can not duplicate" rejection .
