Gear Ratios '05 325i vs. '06 330i
I know that the bmwusa web site has technical info for the current models, but I am having difficulty in finding the gear ratios (transmission and diff) for the above models.
Can anybody point me to a resouce for the same? I am let to believe that the gear box (not just the ratios) are different between the 325 and 330. Does can anybody quantify that for me? TIA. Byron |

OK, I confirmed two interesting things. The gearbox (GS6-37BZ) is the same as used previously on the E46 and is currently on the E60 and E85.
The diff ratio varies. The 330 has the 3.15 and the 325 has a 3.23 diff ratio. The 328 has the following gear ratios with a 3:23 diff ratio: Transmission: Manual gear ratios – I/II 4.32/2.46 Manual gear ratios – III/IV 1.66/1.23 Manual gear ratios – V/VI 1:00/0.85 Does anyone have knowledge of how the transmission ratios vary between the 06 325i and the 06 330i?
