1st gear vibration

[LB1951]

Posting for a buddy, 67 Barracuda 383 4 speed has a bad vibration taking off from a dead stop only at low RPM shift into 2nd higher RPM and it starts to go away 3rd and 4th no vibration. Had the tranny rebuilt and clutch, pressure plate and bearing are all new. Vibration is so bad it shakes the dash. Anyone had a similar issue?

Vibrations are usually caused by 1) something out of balance, 2) something loose or 3) something wearing/worn out. First thing I'd do is check bolt torques on everything and look for loose.

After a couple of calls to Passion and Brewers it was determined that the finish on the fly wheel after being resurfaced is too smooth creating a slip and grab condition. New flywheel on order along with a new clutch as it's glazed over.

That certainly is an odd one to sort out.
Hopefully the new bits sort it out.
Can you post an update?
