I have one creatd by Jim Gunnoe but I can't remember where I downloaded it
from. It's called "Crawl Ratio Calculator" and his email is jimg@cj7.com.
It already has the ratios for the common t-cases and manual trannies. The
ones linked above, you'll have to know the ratios.

Gear ratio calculator online?
Hi all,
Sorry about the semi-crosspost, but I figured these 4 NG's would be my
best bet for a quick answer on this one. I remember seeing a gear ratio
calculator somewhere on the net. Does anyone have this bookmarked or
know where it is?
The one I remember had fields for engine RPM, tranny ratio, transfer
case ratio and axle ratios, giving you your final speed at any given
engine RPM. I'm considering using the stock axles in the FrankenWillys
(http://jeffgross.com/******), but it MUST be interstate freeway speed
capable. I know the complete stock driveline is only good for about 55
mph tops, but I want to use the 88 Toyota 4x4 pickup engine, tranny
(5sp) & transfer and suspect that the stock ****** (1950 4x4 wagon)
axles might be OK. I'm hoping that the ****** 3sp tranny is what
actually eats up the RPM's in the stock driveline.
Any other ideas/opinions/info about these axles is welcome.
Thanks in advance for any help.
Cheers,

One calculator is at http://www.corral.net/tech/gearcalc.html another
is at http://www.4lo.com/4LoCalc.htm and another at
http://www.xse.com/leres/ss/calculator.html Use Google to find
several others.
Note that the high gear in most transmissions is 1:1, so the RPM
you're losing is likely in the axles. That was the reason for
overdrive: make the driveshaft turn faster than the engine, to make up
for the reduction in the rear axle.
Good luck!

One calculator is at http://www.corral.net/tech/gearcalc.html another
is at http://www.4lo.com/4LoCalc.htm and another at
http://www.xse.com/leres/ss/calculator.html Use Google to find
several others.
Note that the high gear in most transmissions is 1:1, so the RPM
you're losing is likely in the axles. That was the reason for
overdrive: make the driveshaft turn faster than the engine, to make up
for the reduction in the rear axle.
Good luck!
