Hi everyone. On deceleration in any gear I hear a winding gear noise that goes away even at less than 5% throttle. Did fluid change in both gear box and final drive with no improvement. Added Liqui Molly MSO2 gear grease in both places and it got worse! Any ideas? Mechanic said is due to straight cut gears in the gearbox. I am pretty certain that's where the noise is coming from.
