HELP 01 Z24 Tranny Problem?????

i had the clutch replaced cuz i didnt have the tools to pull the engine to replace it and it went out like 2 days before my college classes started up and i had to work on top of the fact that i have no idea how. Anyways got the car back and it was really hard to shift and the clutch seemed really loose, well i bled the clutch and that fixed it a little bit still not as smooth when shifting but now it has gotten worse i shifted into 3rd today and it made this grinding noise really loud so for the rest of the drive today i just went from 2 to 4th gear well now it grinds only in 1 and 2nd. Whats going on here? And its hard to shift again sometimes i cant get it into first when at stop lights and have to start in second....however it was shifting fine before i took it in got any ideas ???????? THANKS

You need to take it back to who done the clutch replacement.
A improper installed clutch or defective clutch or clutch slay and/or master cylinder will cause things like that. And also air in slay cylinder.
Is the master cylinder tank full of fluid?
Try bleeding the master cylinder.
Why did they pull the eng instead of trans to replace clutch?
