The car is a 5 speed, TPI G92 with the 9 bolt rear.
The problem -- okay, the car was in storage for 2 1/2 years and it runs fine BUT when I am moving slow (less than 10 MPH) or decelerating, there is an occasional nasty metal on metal clanking sound. It is worse when the car is in an incline/decline position. It sounds like metal on metal that is clanking...or when decelerating, it sounds like something is still spinning and slowing down out of sync. Accelerate and the problem goes away. I am hoping the driveshaft is just banging against the tranny or undercarriage, but it sounds like the tranny might be going. Mechanic inspected the bottom, but found nothing. He thought it might be the gears, but when I felt it this morning in traffic, I felt a vibration in the shifter with the clanking sounds...it was out of gear. Oh yeah, this usually happens with the car OUT of gear and in neutral...as I slow to a stop. When I hit the gas, sometimes I hear a clank too. Any thoughts? Or, any ways I can give a better description? Thanks for looking.
