What Is A Car Transmission?

what does my car transmission doWhether your car’s transmission is top of mind from many years of manning a stick shift or something that’s foreign territory as an always-automatic driver, many people have trouble grasping the full concept of a transmission’s duty.

At Cherry Hill Nissan, we believe that getting to know your vehicle’s inner systems helps you to take better care of them, which is why we set out to increase your auto knowledge power as much as possible. Cherry Hill, Mount Laurel, and Collingswood area drivers asking what their car’s transmission does can check out the breakdown below!

Your Transmission’s Mission

A transmission’s high-level duty, simply put, is converting the power from your car’s engine to its wheels in a controlled manner. Using various gear ratios, the transmission can take top engine revolutions and turn them into usable speeds to get you from point A to point B. Without your transmission, your engine’s high revolutions would be far too speedy for your wheels to handle without spinning out.

Gear Ratios Explained

Transmissions are made up of an input shaft and output shaft that are lined with various notched gears. Gear ratios are set rates that refer to the number of notches on the output gear divided by the number of notches on the input gear and equate the rate at which the engine’s revolutions are converted into torque for the wheels. Matching gear ratios to the applicable driving situation is how you can achieve the speed set you need in an efficient manner.

Transmission Types

While new transmission technology is on the rise with the debut of continuously variable transmissions (CVTs) and dual-clutch systems, for many years transmission choices were fairly straightforward: manual or automatic. Today, most cars and trucks have automatic transmissions at their helms, though manual is still an option for those drivers who are used to making their own gear shifts.

Manual vs. Automatic Transmissions

The biggest difference between manual and automatic transmission function is that automatic transmissions perform intermediate gear shifts for you to produce the right speed ratio. Instead of a clutch pedal that manual drivers press to engage the transmission and make a gear switch, automatic transmissions transmit speeds on their own by using a torque converter and fluid pressure system to engage the transmission and find the necessary ratio for the situation at hand.

Speed Level Distinction

In most cases, as long as the transmission is suited to the engine power level, higher speed levels allow you to use fuel efficiency more wisely with a more exact approach to mating speeds to engine output.

With a four-speed transmission, it’s likely that more power will be misused compared to a seven- or eight-speed transmission that has a more granular approach to turning the wheels at the correct ratio.
