What Does the Transmission Do?

One of the most important components in a vehicle is the transmission. Its components work together to transmit power from the engine to the wheels. However, not all car owners understand the role of the transmission in their vehicles.

If you’ve ever wondered about the function of the transmission in a vehicle, you’ve come to the right place. In this article, we will explain the main functions of the transmission, its components, and the signs of a bad transmission.

Components of Transmission System

A vehicle’s transmission system consists of the following components:

  • Clutch: The clutch connects and disconnects the engine from the rest of the transmission. When you engage or disengage the clutch, you can control the transfer of power from the engine to the gearbox.
  • Gearbox: The gearbox allows the driver to select different gear ratios to match the vehicle's speed and load conditions. This enables the engine to operate at its optimal performance range while providing varying levels of torque to the wheels.
  • Propeller shaft: Also known as the drive shaft, the propeller shaft transfers rotational power from the gearbox to the differential, which then delivers power to the wheels. This component plays a vital role in transmitting torque smoothly and efficiently.
  • Differential: The differential is a set of gears that allows the wheels to rotate at different speeds while turning. It ensures smooth cornering and prevents wheel slippage, especially when the vehicle is turning.
  • Universal joints: These joints are flexible couplings that connect the propeller shaft to the differential and the wheels. They allow for angular movement and help accommodate variations in alignment and suspension.

What Does The Transmission In Your Vehicle Do?

The transmission in your vehicle transfers power from the engine to the wheels to enable smooth and efficient movement of the vehicle. It simply acts as a mechanical intermediary, allowing the driver to select different gear ratios to match the driving conditions and speed. When the driver shifts gears, the transmission adjusts the torque output from the engine, ensuring it operates within its optimal performance range. This process allows the vehicle to accelerate, decelerate, and maintain speed smoothly. In addition to providing power, the transmission also plays a crucial role in enabling the vehicle to turn corners without skidding or losing control.

Signs of a Bad Transmission

It’s important to understand the signs of a failing transmission and schedule auto repair service as soon as possible to avoid a potentially dangerous situation when you’re driving and a costly transmission replacement. Here are some of the common symptoms of a bad transmission.

  • Burning smells coming from your car
  • Slipping out of gear
  • Leaking transmission fluid
  • Lack of engagement
  • Odd noises coming from your transmission, such as clunking, whining, and chattering
  • The transmission light is on
  • The check engine light is on
  • Humming or shaking when in neutral
  • No response from the gearbox

If you notice any signs of these symptoms, have your vehicle inspected at a professional auto repair shop as soon as possible to prevent further damage and potential transmission failure. A transmission replacement can be costly, typically ranging from $1,800 to $3,400.
