Removed from a 2007 Porsche Carrera 3.6 L automatic transmission. It was starting the car but it is weak. I am not selling this item as a 100% working alternator. It needs to be rebuilt. But it's cheaper than buying a brand-new alternator and not difficult to rebuild. 

This alternator is for automatic transmission only. Please be aware when you're purchasing for your car as the alternators pulley is different for manual and automatic transmission
