Another reason why I think you should always leave an SMG car in N. These SMG gearboxes do not have a parking pawl, so there’s no means of locking the transmission output shaft (which locks the driven axles). P just means it’s in a gear.No, no engine is normal to turn when clutch open. I suspect it thinks it's in neutral when it's actually (partly?) in a gear.
You should put a DCT in this one.
