Your Transmission Explained
Replacing your transmission effectively starts with understanding the role that your transmission plays in your car, so let’s take a closer look at what your transmission is, what it does, and how a transmission defect or malfunction can impact your entire car.
What Your Transmission Actually Does
How Your Transmission Works
There are two main types of transmission systems: manual ones and automatic ones. Though they have some key differences, they both do the same basic thing: changing gears so that the right amount of power is delivered to and from your engine.
Automatic transmissions use a torque converter to help your car switch gears.
Manual transmissions require the driver to use a clutch in order to switch to their desired gear.
