What Does a Transmission Technician Do?

Transmission technician might not be a job you’re familiar with, but we depend on them every day. Whether you drive a car, take the bus, or rely on vehicles for deliveries, transmission technicians ensure the vehicles we rely on are functioning properly.

What does a transmission technician do?

Transmission technicians specialize in just that - transmissions. Transmissions are the part of a vehicle that transfers power from the engine to the wheels. These types of mechanics specifically work on advanced parts such as hydraulic pumps, gear trains, and couplings - inspecting and identifying any issues or problems that arise. In addition, they test parts, provide routine maintenance like oil changes and brake pad replacement, and study technical manuals to ensure up-to-date knowledge of any new automotive technologies like integrated electronic systems.

What is the difference between automatic and manual transmissions?

Just like there are different models and brands of cars, there are different types of engine transmissions. The basic difference is that an automatic transmission changes the car’s gears according to engine speed while manual transmissions require the driver to use a clutch to change the gears themselves. Manual transmissions are often less expensive, and the driver must use both feet and both hands to drive, requiring even greater concentration then when driving an automatic transmission car. Though an automatic transmission may be more expensive, they provide a more comfortable and convenient ride.

These driving differences translate over to transmission technicians as well. Manual transmissions are often easier and less expensive to fix than automatic transmissions. This is due to less complicated features in a manual transmission. Because automatic transmissions are becoming increasingly computerized, this means the technicians repairing them not only have to understand cars but must also possess strong math and computer skills.

How much does a transmission technician make?

We depend on cars, trucks, and other automotive vehicles which all need repairs and routine maintenance from time to time, so transmission technicians play an important role in our society. On average, a transmission technician can make around $42,000 per year, or $20 per hour. Transmission technicians also have a variety of options when it comes to employment, working for a locally owned repair shop, operating their own business, or working in the service department of a dealership.
