My clutch makes a GRRRR or Buzzing noise any time it engages in first. However it never slips but some times getting the gears in place is difficult.

2nd gear is rough, 3rd gear grinds and 4th gear is rough when shifting at high RPM or when im drag racing.

My friend says its my pressure plate along with old transmision oil.

What do you guys think?

edit:

what i mean by rough is that it locks up.
