after i installed my new clutch, everytime i take off in 1st gear my car starts shaking right before i take my foot of the clutch. we replaced the clutch but i dirent replace the T.O.B(throw out bearing).u guys think thats the problem?and everytime am driving in 4th gear and i let go of the gas and the rmp's go down and they hit 2300 it makes a grindind noise.i know its not the transmission because before i installed the clutch it wasnt doin that. thanks
