Driven home for work and I heard a clunk and I quit moving coasted to a stop got the truck home and did what I thought the problem might be jack up the rear end and park works but everywhere else the wheel can freewheel took off the plate on the bottom of the tranny to see the torque converter and it spinning as soon as I start the truck. now I am clueless on what happen any ideas guys p.s. the truck is a 2001 2500 4x4 with an auto (not the one in my signature)

 

Input shaft snapped, maybe.

 

Well your right it was the input shaft 1800 bucks to get it fixed
