Transmission noises... normal?
Good evening ladies and gents, I'm a proud, 3 day old owner of a c5 z06
28,000 miles
Museum condition.
Owned by someone who religiously changed the oil and maintained the car.
The only modification he did was a Hurst short throw shifter.
Now I have read that an aftermarket shifter transmits more sound than the stock shifter. I do get a faint whine under load, at cruising speeds/loads it goes away, but I feel like there may be excessive other noises as well.
Slight whine
Occasional slight whirring noise
Clicking noises at low rpm. (Occasionally)
Clicking noises when the clutch is in and I'm putting it in gear to a downshift.
Are these normal? Am I just hyper sensitive to normal racecar noises? Or should I be hearing next to nothing but the engine rev and exhaust note?
Many thanks!
- Nate

Our Trans are Trans axel. Meaning they are mounted in the rear. They are said to chatter a bit. What your hearing probably is normal. I can't say I hear a whine in mine. But it deffinatly does make alittle noise from time to time. Maybe a fluid change would be a good idea for you. I recently did mine at 10k miles and it got a bit smoother.
The clutch makes noise if you don't hold the pedal down when Shutting off the car. That is normal. And threw me off when I got the car.
Enjoy your new ride!

Does the whine sound get progressive as the car accelerates in gear and seems to be from center of the car toward dash? Sound like a mini supercharger? That's normal as far as I can tell mine does that so don't other C5 Zs I have driven.
If it's a more audible, higher pitched whine emanating more from the rear of the car then could be bad or thirsty diff.
These cares are very light with little to no sound deadening, all kinds of sounds permeate the cabin- drive around for a couple hours with the radio off and you hear all kinds of mechanical noises, the chatter w/ clutch in @ low rpms is normal and I have heard it on other manual tranny Vettes before

You're spot on with the mini supercharger in the center of the dash.
Exact noise (too bad there isnt a KB blower under the hood! )
I appreciate both replies, that settles me greatly. The car is strong, pulls hard, turns tightly, and is in mint condition. Ready to be driven.
Thanks guys.
