BMW 6 Series - Tech Talk E24,E63,E64,F12,F13
I'm wondering if anyone knows if there are any physical differences with the 645 diff's for manual and auto cars.
I have looked up the part number via my VIN (Manual 645) and get 3310 7525199 with a 3.46 ratio, now the automatic diff comes up as the same ratio 3.46 but a part number of 3310...
