I've had my CS six months, and have been experiencing very loud transmission gear whine. The condition is 5th gear 1800-1900 rpms (44-45mph), and 6th gear 1800-1900 rpm (52-58mph). Does your vehicle have this issue? I have had it written up 5 times, the last response I received was "deal with it, it's a characteristic of the vehicle".

Please let me know if you've experienced this issue.
