I have a quick question about my 2017 Raptor's transmission. My truck has about 22,000 miles on it and I don't remember it doing this before but in the last month or so every time I back the truck up, I come to a complete stop, shift the truck into Drive and before I remove my foot from the break it jerks forward. It does this more violently when the truck is cold but it still does this when its warmed up as well. Should I be worried? Should I take my truck to the dealer? no check engine lights are on. Also does your truck still shift rough in sport mode? I haven't driven it in sport mode a lot but when I do it shifts really rough.. thanks for all your help.
