2005 Corvette (C6), 59k miles, manual.
Took it on the interstate today and out of nowhere I’ve got a new noise that wasn’t there yesterday.
In 5th and 6th around 65–70 mph under load it makes a noticeable high-pitched whine (almost like a supercharger). As soon as I lift off the throttle it goes away, and it also fades out by ~80 mph. Sounds like it’s coming from the center/front of the car.
No grinding, clutch feels solid. Only other thing is 2nd gear can be a little notchy at times, but I do have a short throw shifter so not sure how much of that is normal.
Is this typical C6/T56 overdrive gear noise or something starting to wear? Planning to change trans fluid next, just trying to gauge how concerned I should be.
Car is a blast compared to my Mustang, but man it’s been keeping me on my toes since I got it.
