How do you tell gear ratio?

[Chico01]

Ring Teeth........... Pinion Teeth......... Axle Ratio
30...............11.......................2.73
37...............12........................3.08
36...............11.......................3.27
39...............11.......................3.55
41...............11.......................3.73
41...............10.......................4.10
41...............9.........................4.56


tip - if your looking for 3.73, a banged up Explorer or f150 at the boneyard can do the trick

ok I want want to get this opportunity and ask about the gear ratio thingy.. I surfed around sites and see lots of gears info then I cam across a chart like this..

1st gear - .345
2nd gear - 1.34
3rd gear - 2.11
4th gear - .433
5th gear - .923

final gear ratio - 2.340

what the hell do those mean? How do they related to the gear ratio the car has? (3.27, 4.10, etc..)

What the hell kind of transmissionis that? On my T5 these are the ratios:

1st: 3.35
2nd: 1.99
3rd: 1.33
4th: 1.00
5th: .68

Final drive gear: 3.73

The gear ratios should get smaller with each numerically higher gear. Those numbers you have suggest that 4th gear is taller than 5th, which is retarded, and 2.34 gears in the rear-end? What the hell? That is some BAD info.
