Automatic Transmissions for Dodge, Ford, GM Diesel Trucks
Automatic transmissions have largely replaced manual onesreplaces the manuals as consumer’s transmission of choice. This type of transmission allows an engine to operate in a much simpler fashion for its driver: it provides a large range of output speeds from the engine’s narrow range of speed. Automatic vehicles will notably lack a pedal for the clutch or a gear shift, as they are superfluous to the working of the vehicle. Once the transmission is in drive, everything else the vehicle needs to do occurs automatically. The parking brake allows the vehicle’s operator to lock the transmission, which will prevent it from spinning. This is necessary as an emergency measure for driving throughout variable terrain types.

One integral piece of this transmission type is known as the governor. Governors are valves which direct the transmission based on how fast the car is going. They are connected to the transmission’s output, so as the vehicle increases in speed, the governor follows suit. Inside this piece is a spring-loaded valve that closes or opens, varying in proportion based on the speed of the governor’s spin. As the vehicle speeds up, it will begin to pump the fluid at ever increasing pressures.
Five of the most notable aspects of the automatic transmission are:
-An overdrive feature on four speeds that automatically chooses which gear to apply as determines by the speed of the vehicle’s movement and position of the throttle pedal.
-Lower speed shifts when the vehicle is gently accelerated than when it is at full throttle.
-A strong push on the gas pedal will cause the transmission to downshift into the next lower gear
-If the car is going too fast for a particular gear, even when it is shifted to, the transmission will prevent the shift from occurring until the car slows down and it is safe to perform the downshift.
-A transmission which is placed into second gear will not shift down or up from that gear unless the shift lever is moved, even from a complete stop.
Under the cover of an automatic transmission is usually a gear pumped that is used to draw fluid from a sump, which is another way to describe a pump used to extract water from a basin collecting it. This will subsequently be fed to the hydraulic system, the transmission cooler, and even the torque converter. This will cause the converter to spin at the same speed as the engine.
