1999 Ford Taurus Rolls in Gear

Hi Guys,

I did some work on my taurus yesterday, wheel bearings, tie rod ends, sway bar links, and ball joints. When I was all finished, I put the tires on, and was cleaning up, I kicked the chock out from behind the back tire. The car rolled back and made a clunk noise. Now it rolls in all gears. I checked the shift linkage, and everything is is the proper location. When I start the engine, and put it in reverse, the engine revs up slightly, and when you step on the gas, revs like it is in neutral. When I try to put it back in park, the gears grind horribly, and I just shut if off right away. When in any of the forward gears, it does the same thing, doesnt move. I put it up on jackstands again today, and check the axles, and both are seated properly to the trans. I checked all fuses, and everything is ok; I am power cycling it as we speak. Please help!

Thank you!
Rob
