a few days ago was hauling a skid loader back to a friends house. after i dropped it off i went to pass a slow moving truck on the highway..chip was set at 50 horse with about 3/4 throttle. trans downshifted i got beside the guy and all of a sudden...SNAP! thought i lost a ujoint so i pulled off the road and come to realize it was not the ujoint. tried 4x4 thinking something in the rear end broke..still nothing. i have no reverse or forward. when i put it in gear the truck just revs as if it was in neutral. i feel like i broke a input shaft or possibly a torque converter?
trans was shifting fine and tc was working fine before this happened. any ideas as to what could have happened? and info would be greatly appreciated. thanks guys.

 

well turns out it was a torque converter. second one ive been thru in a years time.
