how can you tell if your clutch is slipping. i just got (all brand new) motor tranny clutch pressure plate all that stuff. When i go over the speed bumps and then giveit some gas it feels as though im spinning the wheels but it doesn't make any sound or slide out from under me. after a second it catches and i go but it was concerning me. its a torquey 388 with not a race clutch but its not stock either. if i got the numbers for hp and torque for the clutch would that tell me or are those numbers just general ideas. thanks.
