Ok ive got a real stuff up now,when undoing the nut somehow i managed to pop the shaft that the bolt screws onto and it was as if it was'nt selecting any gears(just spins round and round) so i popped it back into place and i can select through the gears again using a crescent on the shaft.Now when i put it into park it won't start,i have clicked through all the gears and tried starting it but it doesn't start on any of the gears selected,help is reeaally appreciated.
