Several problems i've been havin with my drivetrain:

I was just peeling out around a corner and shifted into second and it grinded until i took it out. I was sure that i had the clutch to the floor and now when i downshift into second, i have to push much harder for it to go in. Another problem that i've been having, is every now and then when im at low RPM's and i downshift from 5th to 4th, it grinds for a second, then goes into gear. I also noticed that the fluid in the master cylinder resorvior was dark. The only reason i can think of that caused these problems was when I burnt the clutch badly when i was peeling out. I had only known how to drive a stick for probably a month, but i shifted into second while the tires were spinning and then into third. The clutch pedal felt like it lost pressure. The car reeked of a burnt clutch for a lil while and now my car does things that i mentioned before. Does anyone have any advice?
