Cars are incredibly complex machines that have a seemingly infinite amount of moving parts that perform various functions. The more you know about your car, the more easily you’ll be able to self-repair and know what to look for when buying a new vehicle. Here are the different types of transmissions that commercial cars typically have and how they work.
The first kind of transmission is manual. Manual transmission has a movable gear selector and clutch. The driver has to manually select and engage each individual gear ratio. Without the clutch, both the engine and the vehicle would stop. The clutch allows the engine to keep working when stopped at a traffic light or stop sign. The three different stages of manual transmission are fully depressed clutch, clutch slips, and fully released.
Automatic transmission is what is used mostly today and is significantly easier than using manual transmission. There are several different stages of transmission that all complete a unique function. The first is Park (P), where the transmission becomes locked and therefore restricting the vehicle from all movement. Always remember to make sure that your vehicles is at a complete stop before putting your transmission into park, because doing it while moving can damage your transmission.
The next transmission function for automatic is Reverse (R), where the transmission is put into reverse gear, which makes the vehicle move backward when you push the pedal. Just like in park, always make sure to come to a complete stop before you start moving in reverse.
The Neutral (N) function disconnects the transmission from the wheel. You typically use neutral when you need to push the car, as leaving it in neutral will cause the car to just roll.
Drive (D) allows the car to move and accelerate through the range gears your car has to offer.
First (1) and Second gear (2) both serve similar functions. Putting your car in first gear means that your transmission is restricted and cannot go past first gear, and when switched to second gear your transmission cannot pass second gear. Switching to first and second gear can be helpful in situations such as towing when you need a lower gear for more power. Second gear can also be useful when spinning your tires in snowy weather.
A newer type of transmission that car companies are starting to put in their cars is Continuous Variable Transmission (CVT). This transmission gives the driver more power and better fuel economy. Floor the accelerator of a CVT Transmission accelerates the vehicle continuously as opposed to a sudden burst of power with automatic transmissions.
