Cars that area unit equipped with a manual transmission require the driver to maneuver a knob that controls gear switches. If you’ve never driven a stick shift, you may have a number of questions. As an Example, one wonders how just moving the knob on the stick actually change the gears? And what makes the grinding noise when the driver doesn’t move it correctly? In this article, I’ll describe how manual transmissions work, answering those questions and others along the way.

Transmission Basics

First, let’s talk about why your transmission needs to switch gears while you’re driving. Automobile engines area unit restricted by a feature called the “redline”.” The redline is the highest number of RPMs that the engine can endure without failing (or bursting from the stress). Horsepower is required in odor for the car to accelerate. The engine horsepower has a top level efficiency at any given point of RPMs. By shifting gears, your transmission keeps the RPMs below your engine’s redline while leveraging the existing horsepower.

Your transmission and engine area unit bridged by a clutch. In essence, the clutch is the connection between you, the transmission, and the engine. Also, keep in mind that the gear ratios sharea unitd by your engine and the drive wheels can vary in different gears. A 5-speed transmission changes the gear ratios as the driver shifts from first through fifth. Doing so allows the engine to make the best use of the available RPM range as your car accelerates.

How To Shift Gears

If you’ve been driving a stick shift (or manual transmission) for awhile, you’ll be able to imagine the stick positions easily. From a top view, they looks like 2 capital “E’s” placed back-to-back. The transmission is in neutral when the stick is set in the center. Shifting from neutral to first gear requires moving the stick to the top right. Second gear is located in the top left. Changing gears on the car involves moving the stick in the directions of middle right, middle left, and finally, lower right to shift into fifth.

As a point of interest (to some people, at least), it’s interesting to note that shifting the stick through the gears – specifically from left to right and back to left – uses different rods and forks, which engages different collars.

Learning To Love Manual

One of the reasons why many drivers enjoy manual transmissions is because they can better control the car’s power. They’re able to maximize the horsepower and torque available from the engine in a given range of RPMs, shifting to the next gear when it’s most efficient to do so. That said, driving stick shift isn’t for everyone. But, understanding how manual transmissions work in order to power a car can be valuable for any driver.
