Driving the car like a limo the car dont go through the gears smoothly, she jumps slightly from first to second gear then goes into the rest of the gears smoothly. Its like the bands were not doing their job properly? When turning a ninety degree corner ( left or right) you hear a light grating noise coming from the knuckle joints of the drive shafts? I think thats where the noise is coming from! There is no grating driving straight. Hope you can help, thx ALBERT.

This seems a software issue and should be dealer serviced to allow the updates

And sound is a notoriously difficulty in properly diagnosing from cyberspace, your guess is reasonable and as good as mine. Have that inspected as well.
