Gear 6 Incorrect Ratio

The transmission is not achieving the correct gear ratio in 6th gear, meaning the engine and wheels are not synchronized properly for that gear. This could indicate a mechanical problem inside the transmission or a sensor fault. You may feel the engine over-revving in 6th gear or experience poor fuel economy at highway speeds.
