dear corvette experts...
I have reviewed similar posts in archives but mostly refer to Muncie shifter. After a recent engine rebuild, I have noted shifter vibration under load. It is clearly not the transverse reverse gear lever on the stick. The car is 'baby blue', my 1967 327/300 (now plus) trophy blue convertible with M20 muncie transmission and Hurst competition plus shifter. What is the differential diagnosis of shifter vibration under load.

vibration or severe vibration like something is coming apart, can you describe in terms relating to magnitude and frequency?

Since the engine and trans have just been re-mated to one another, check the u-joints and make sure the caps are seated correctly. Dennis

also the rear bushing in the tailshaft and driveshaft yoke

Have any shake in the clutch pedal?

Make sure all your spark plug wires are on.

Need a better definition. Is your vibration a "shake" or a "buzz"? Or what?

Make sure all your spark plugs are installed.

I would even go as far as to check the resistance of each wire. I have had a burnt wire many times and the shifter vibrates under load due to the miss fire.

my 'shifter shake' is a rapid low amplitude vibration, I suppose one could call it a 'buzz', it occurs during higher RPM with acceleration, more prominent in the lower gears. Rich weddle

PS the clutch pedal does not have any abnormal vibration
