Sometimes when i let out on the clutch from a stop while giving it gas the tranny shakes really bad. It does this while going straight but it does it more often when i'm turning or when i'm backing up from a stop. I also noticed it does it more when i'm going up a driveway or something like that from a stop. It also does this sometimes when i'm turning right or left in 1st and sometimes 2nd gear. My tranny mount is a new ES poly mount. and everything on the tranny is nice and tight. What do you think this can be. Do you think my clutch or input shaft is crooked? Or do you think this is my posi unit going out? I gotta replace my Stock DS because it is unbalanced and the car shakes at speeds over 85mph. But i gotta figure this out to since it is driving me crazy. Please help me. Thanks.

 

If you're using a good clutch with a strong pressure plate you're probably throttling too much before letting out completely on the clutch, causing clutch chatter. Or the clutch and flywheel are contaminated with oil or grease causing it to grab.

 

the shaking you get when you go over 85 is probobly just you tires... they might not be balenced all to well...try going faster and see if it smooths out if it does then that is what that is.
