Q: Loud knock and not truck will not drive when gas pedal is pressed down

asked by on

We were driving approx. 70 mph and heard a loud noise from under the truck. It sounded like we ran over a huge rock the hit the bottom. Pulled off right away and parked. Truck will turn on and shift into gear but will not move forward when I step on gas pedal. What might be wrong and will it roll if in neutral for tow?
My car has a manual transmission.
