I have a 2009 FX4 S/C f-150. It unfortuneatley has the all so common shifting issues but it also has the loudest "Clank" when shifting from Park to drive or reverse. Its worse on any sort of an incline and the use of the park brake has very little effect. Any ideas or similar problems? Also just put in the K&N cold air intake.....AWESOME! noticable increase in power and sounds great.
There's a Teflon grease that's supposed to help where the driveshaft goes into the transmission. The splines get sticky and don't slide as well as they should. That may or may not be the problem but is likely.
