5-45RFE: (Hemi)
1st - 3.00:1
4th - 0.75:1
5th - 0.67:1
48RE (CTD)
1st - 2.45:1
4th - 0.69:1
So the Hemi has lower 1st and 4th gear ratios, to put the engine at a higher rev, plus the higher overdrive ratio for highway cruising.
Coupled with the Hemi's lower 4.10 RE (as opposed to the CTD's 3.73 RE), the Hemi should be well within it's power range, right?
So, again, why is the CTD rated 200 lbs higher for GVWR and 3K lbs higher for GCWR? :?
