I have a friend that is looking into a new 4500 with a stick. Does anyone know what model of transmission is used in the C&Cs and what the ratios are?

The "new" G56 has the shorter final drive ratio. The older one ran MORE rpms at any given speed in 6th gear. Thanks BroncoHound for the correction.

-----old , new
1- 6.29 , 5.94
2 - 3.48 , 3.28
3 - 2.10 , 1.98
4 - 1.38 , 1.31
5 - 1.00 , 1.00
6 - 0.79 , 0.74

R - 5.74 , 5.42

Here's a neat app to calculate gear ratios and effects of changes to rear axle ratios and tire sizes.

quoted from another thread, the g56 in the c/c is the "new" column
