Transmissions are a remarkable machine. Transmissions are able to shift your car using a series of hydraulics and electrical components. Transmissions are made of a few main parts of the system:

Torque Converter: With a manual transmission your engine connects to the transmission by a clutch. An automatic transmission needs a torque converter to connect with the engine. The torque converter is a type of fluid coupling which allows the engine to spin independently of the transmission.

Engine Sensors: There are several engine sensors. These all need to be working for your car to be working properly.

Gears: Main gears and planetary

Fluid: Super important part of a transmission. It is usually red so if you see red leaking you know what it is.

Filter: Catches all the debris. This needs to be cleaned or replaced for optimum running. Checking the fluid twice a year is highly recommended. Low fluid could cause the car to shift poorly and can lead to serious damage to your car. Both automatic and manual transmissions accomplish the same thing but do it in different ways. A manual transmission requires you to push in the clutch with your foot and change gears where automatics do it for you. Cars need transmissions because of the physics of the gasoline engine. A transmission refers to the mechanisms which provide speed changing gears to your car.

Leaks: Not environmentally friendly. You want to be responsible for leaks. DEQ (Department of Environmental Quality) requires you to manage transmission fluids like used oils. Do not allow transmission fluid in storm drains, septic tanks, dry wells, sewer systems or dumpsters.
