Asked by for the 2003 Ford Windstar
I'm assuming the engine revved up, but there was no engagement from the transmission? Did you try to shift from Drive to any other gear - and did it do anything different?

You could have something as simple as a transmission range (TR) sensor issue, or as complicated as an internal transmission failure. You will certainly need to get some assistance in the area -- here's a link to some shops in your area. http://repairpal.com/directory?address=77642&car_brand_names=Ford

Good luck!
