Well friday i was driving down the road cruise control set at 75 mph, headed out to go fourwheeling. The truck felt like it had a bad vibration in it ever sense i made a pass down the strip the week before. Cruising along it started to get louder and louder and then bang. Felt like the trans popped out of gear. Removed the inspection cover and could turn the tq converter with a screw driver. Think the stock fly wheel/flex plate is dusted???? Sure didnt seem like i broke the crank because ive done that before the motor build.
