I have a 2003 Ranger with the 2.3 duratec Auto 5 speed and 4.10 rear. I've never owned a ranger or a ford. I wanted to know if i'm hitting overdrive or not. When driving at 75mph my rpm's are 3k (or more). To me this seems a little high but im not sure if its just a ranger thing. My tire size is 235/75r17 and it is lowered. My O/D button does work but i'm told all that does is keep you in a lowered gear. Could someone let me know if this sounds about right?

 

that sounds about right

 

so my ranger to has 4:10 and this is the result that just came up , yeah it says adding up metrix , i have a 3.08 gear , my door tag say 87 or 97 meaning 4:10 so why it telling its 3.08


Answer:At 70 mph with 29-inch diameter tires at 2,500 RPM, the calculated gear ratio is 3.08:1.
