i hear whine when im in 5th and 6th. It goes away as soon as i let off the gas. Ive had the pattern checked and backlash checked. Im at .010 and the pattern is dead center. No idea why it whines. Im starting to think its the transmission and the sound it going through the drive shaft. Since it starts around 40 mph in 5th but if i drop to 4th and maintain 40-45 mph i can heard it (could be due to my exhaust tho). Im gave up on fixing the whine.
