Hi, All. Proud first time, new owner of 2010 QP 4.2. When it is cold, engaging D or R produces a definite 'clunk'. It is still noticeable when the engine has reached temperature but very much reduced. Gear changes when driving are smooth and in general the car runs beautifully. Is this the sign of something more worrying or is this just Maserati gearboxes? Any help gratefully received.
