Tranny Ratios

Just bought a 1995 F-150 supercab with the 300 inch six. It has a 3.08 rear end ratio and a five speed manual tranny. I want to get the ratios for the five gears without spending a lot of bucks on the spec book. I called dealer's service, but they said they don't have time to look stuff up for people. Ford's main customer service line says they don't have the info.

Thanks.

In case anybody else is interested, I called the ford garage and got them, at least for the '95, F-150 supercab, 4.9 l six:

1 3.90
2 2.25
3 1.50
4 1.00
5 0.80
R 3.39

Just my 2 cents worth. The F250 has a lower geared trans. Very similar to the old 4 speed with the addition of an overdrive.

Tranny Ratios

I could see the F250 having lower gearing as it is heavier. My previous truck was an '84 F-150. It had the 4-speed with a 2.47 rear end (I thought a 3.08 was a highway gear?). The ratios are:

1 3.01
2 1.78
3 1.00
4(OD) 0.71

That gives it a overall final drive ration of 1.75. It would turn about 1300 RPM at 60 MPH. compared to my new (95) truck (rations listed above) has an overdrive (5th gear) of 2.5 overall ration. Also 1st in the '84 was pretty high.
