Mustang5L5 said:2003 amd 2004 GT's and Mach 1's have a steeper overdrive in the 3650 than the 01-02's.
01-02's i beleive have a 0.67 or 0.68 5th gear while the 03+ 3650 has a 0.62 5th gear
So you 01-02 guys (and older) would be spinning slightly higher RPM's then the 03+ guys
I think you have it backwards. Bc in my 02, in 5th and running about 70 i'm only taching like 1800-2000. So unless i'm just getting the gear ratio all messed up i think i have like a .62 overdrive. Or i have like 2.50 gears haha
