So I have been a Ford guy since about 2003.. Had probably 15 of them or more. Currently have 3 of them. I bought a 2020 F450 Limited to use primarily for towing a 19K pound 5th wheel and occasional other towing needs. Went out this am to hook up a trailer and the wrench light came on.. Then the truck wouldn't move in drive or reverse... I shut the truck off and restarted it, Could then move it in Drive as well as reverse.. But the wrench light came right back on.. Off to the inter web I go and apparently the 10 speed transmission is a problem child in these trucks.. Have an appointment this week at the dealer to look at it. Truck has 15k miles on it so its under warranty.. Hopefully its a simple fix and does not tie up the rig long... Its supposed to be pulling our camper to Fla next month..
