Sometimes when my car shifts from 1st to 2nd, it makes a clunk noise. Its been like that for the last 2 years i have owned. My uncle had it checked out when it was under warranty, and GM said there was nothing wrong with the car. Does anyone know what this might be? Ive also been hearing a whining noise when letting off the gas lately, but this just started.

One more noise while im at it. A clicking noise when driving slow, but that was only a one day thing, coming from the front of the car

1996 Z-28 Automatic, 62,000 miles

 

Clunk noise when shifting...prolly a trans mount..easy fix.

 

Could it be a trans mount even if it dosent do it all the time? And should i replace with a polyureathane trans mount??
