I have a 1977 4 speed corvette. When I shift the gears I can see a vibrations in my rear mirror. Once I get into four gear the vibrations goes away. I just had a new clutch put in and the mechanic told me that my transmission looked ok. I had the vibration before the clutch was put in. I know I'm not giving ya'll very much information but just hoping someone may know something. Thanks in advance.

Yea, that is a bit thin to go on. You realize this car is almost 40 years old right?

Just to try and get a little more info out of this. Do you feel any vibrations in the steering wheel? Or maybe in the butt of your seat?

No vibrations from steering or underneath seat.

Is this vibration only when you have the clutch pedal fully depressed and do you feel the vibration when the car is standing still with the pedal fully depressed?

Don't overlook the possibility that your mirror may just be loose.

Resolved this problem in a friend's Camaro...
Trans yoke was worn and yoke bushing was shot. In fact, the worn section of the yoke measured .045" less than the unworn portions!
