Hi All, Depending on whether the car has been running for a while, every time I put my foot down to over take there is a shuddering that seems to coming from the gear box. Is it because a lack of oil? I bought this car in January it's a 2006 Sovereign 3. Liter. Sometimes it's fine and the the kickdown works perfectly it has had a full service and MOT in January. Any ideas ? Keith.
