Driving down the interstate truck was running perfect. Went to shift from 4 to OD and somthing happend wouldn't go in gear. Brought the truck to a stop but it was hitching up a little. Transmissions in neutral at this point. Started truck back up and it idle little rough doesn't show any boost being built When reving it up. When tow truck was loading it you could see truck hitching after every rotation of the tire. Clutch peddle was stuck down 3/4 the way down. Today its back to normal position. Still couldn't shift into gear. Idk what happened looking for any input thx.
