The Simple Side of Gear Ratios We'll start with a look at the simple side of gear ratios. Archimedes would recognize that gears are a form of leverage.

The crawl ratio is a simple number that you can find by using the following equation (First gear ratio in the transmission x the transfer case low range ratio x the differential gear ratio).

By comparison, the new Wrangler Rubicon with a manual transmission has a first gear ratio of 4.46, a 4-to-1 transfer case, and 4.10 axle ratios. This equates to an enormous crawl ratio of 73!

A higher overall numerical gear ratio raises rpm, and a lower numerical gear ratio lowers it. Simple, right?

For many people, driving is as simple as hitting the gas to go — for more engine power — and using the brakes to stop. But your motor can actually help slow you down in certain situations, too. It's ...
