When slowing down the vehicle and almost coming to complete stop the truck shutters when it shifts down. Also, if slowing down and almost coming to a stop and then accelerating the truck hesitates, and then shifts hard. The truck hesitating has caused a delay in clearing traffic while turning to exit the road.
While driving my truck it shifts into tow mode by itself, also on june 1st 2025 my truck shifted to 4 low by itself .
