Do you mean you can't move the lever into the park position or that when you move it into the park position it does not keep the car from moving?

Thank you both for the fast reply. I can shift the laver all the way over to the park position,however the truck remains in reverse. It does however go into park at times as it should but it is a never know when it will or will not work correctly thing. I have looked in to it all over the net and seems like it may be just an adjustment thing, at least I am hoping it is .There are Ford dealerships here but at the Euro to dollar rate I know just having them ( Ford ) look at it will cost me my first born and then some.Again thank you for the responses.

Hopefully it's just that the linkage is out of adjustment. It could also be the parking pawl inside the pan is not being actuated by that linkage or is broken off. I have no idea how to go about getting service on an American vehicle in Germany, but I'd guess that some of your buddies have had experience of this nature.
