i think i got a problem with my transmission. everytime i'm in second or third gear and i rev the engine at like 5k or 6k rpms the car starts making this grinding noise. its not too loud just loud enough so you can hear it i can also feel it a little bit through the shifter. this only happens when i'm in second or third but not in any other gears. do you think it could be my clutch that is no good.
