In the last month when I shift my 2000 F-250 Powerstroke into D it stays in neutral, I have to drop it into 2 and then bump it back into D for it to go into gear. Once it is in gear it shifts fine. Is this just the linkage or is it internal. Truck has just over 100k, I got it in 2009 at 85k and have used it to tow my boat a few times as well as for camping trips and drives to Powell with all our stuff. It was used to tow a fifth wheel horse trailer by the PO.
