I have seen some posts concerning gear whine with at least one person who had rear end gears replaced but still has the whine. I have the whine in 3rd, 4th, 5th, and 6th with the noise level going up as you run through the gears. It is the loudest between 2000 and 2500 under cruising conditions. In sixth gear you can hear it over the radio. Has anyone else had this problem and does anyone have suggestions. Is it the transmission or rear gears? I have heard others say the sixth speed tranny has more noise but I can't believe this much. Still have the stock shifter, wanted to go to Pro5.0 but if aftermarket shifter makes this worse don't want to go there.
