    That seems odd. Does it happen when you manually downshift, or when the trans automatically downshifts? If its all okay so long as you don't downshift manually on your own and let the truck do it, I would do that to get to a shop.

    This is not a very good descriprion of the problem, does it loose throttle all together or just doesn't want to pull, do you have auto or manual trans for starters and when you say loss of power is it engine doesn't pull or battery power coming off any messages in the dash, even if truck is deleted if you connect to 1.12 ptt it will show codes.
