V1 F40 guys chime in

[Desert Sasqwatch]

The MU9 (GM code number) transmission, which is manufactured from 2008 and newer, has the better gear ratios (3 thru 6) and final drive ratio (3.76). A 3.89 and 4.17 final drive ratio was available in Europe, but not in the US.

Note: the 3.76 ratio with a 25.0 inch tall tire will reach 60 mph at 2nd gear redline (6200 rpm) so only one gear change needed to arrive at that speed. Short gear ratios - 3.89 and 4.17 - require a second gear change into 3rd gear to get to 60 mph. Just some additional information.

4.17s sound fun, but turbo cars love load
But really, 4.17s could be a lot of fun in a 6spd car and still be able to cruise at dumb low rpm on the highway.
