Transmission Leak Inspection
What is a transmission, and why might it leak?
The transmission is responsible for receiving power from the engine, and sending that power to the driveshaft or axles so that your car goes the speed you want. An automatic transmission adjusts on its own to driving demands, and keeps the engine running in an optimum range for a given speed.
The transmission oil pan gasket is the most common source of a leak, but fluid may also escape from loose seals, damaged transmission lines or a cracked or punctured pan.
How does a transmission work?
Automatic transmissions use the force supplied by the engine to pump pressurized automatic transmission fluid through many components. As the pressure increases or decreases, different clutches or bands will get activated, and these determine which gear your car is in. The higher the gear, the easier it will be for your car to go faster.
