Manual transmissions aren’t necessarily simple, but they’re much easier to understand in concept than their automatic counterparts. You’re probably aware there are gears in manual transmissions - but there’s a little more to it than that. Here are some of the major components you’ll find in a manual transmission.

Shafts - There are three main shafts inside a manual transmission. There’s an input shaft where engine power is transferred via the clutch, and that drives the layshaft, also known as the countershaft. The countershaft has different sized gears to achieve various gear ratios. Corresponding gears on the countershaft connect to the output shaft. The output shaft is connected to the driveshaft, which powers the differential.

Are you considering upgrading to a better transmission on your classic? National Brake & Muffler in Griffin, GA can help.  If you drive something old, there’s a good chance it has fewer gears than you’d like. With all the 6 and 8 speed transmissions on the road today, it’s hard to imagine that just a few decades ago we were getting by with just 2 or 3 gears. These days, there are some simple swap options - here are some things for you to consider.
