4th 5th 6th Whine
Picked up a 02 Z06 with 134k on the clock today. Wanted to see if anyone has an idea why it whines in 4th,5th and 6th. There is slight whine in 3rd and if you press on the clutch while in those gears the whine goes away.
The past owner thought it might be the diff but being there is no noise in 1,2 or neutral I have my doubts. The car is pretty much stock
Thanks in advance.

I would also have to say you most likely have a differential issue.
I also agree on changing out the trans ATF. You have a later trans and can use synthetic ATF. Your shifts will improve. While you have the car in the air, change out the differential lube. Make sure that you get a good GL-5 75/90 weight that has limited slip additive.
The differential whine has more to do with the amount of TORQUE that is being to the gear. In the higher gears, you are applying more torque / load on the ring and pinion.
