Quick question lads. Recently, in the last 2 months or so the gearbox has become a bit laggy, more recently it's been hanging on changing from 4th to 5th in regular Drive but will shift fine with Tiptronic. In Drive it will also sometimes go into Transmission Failsafe if I take a corner and go for a kick down if the car is only running 10/15 minutes. This is resolved by turning the car off and on again and it's good again.

There's also a whine from the gearbox when shifting into 3rd. We suspect it's leaking, would low oil account for these problems?
