Locked gears

My car firstly had a weird sound when putting gear five, then I kept driving and its just had this loud noise from the passenger seat and all gears got stocked. Took it to a mechanic and a new clutch kit was putted, a new bush and gearbox oil was also putt in. After that loud sound from the passenger seat was reduced but now the problem with gears still remains. They are locked will not go to any gears.
