If you are in need of a new transmission for your automobile, truck, or tractor there are a few things to know about the important engine part before you make a purchase. Here are some important terms and definitions with which to familiarize yourself.
Automatic Transmission - As opposed to a manual transmission, where the driver must shift the gears, an automatic transmission shifts itself. Instead of a pedal clutch, there is a torque converter.
Clutch - A clutch is the mechanism that allows the driver of the truck, tractor, or automobile to disengage and engage the power supply from the engine to the transmission. Disengaging temporarily allows the driver to shift. This type of transmission is known as standard, or manual, transmission.
Shifter - The shifter is a required component of the standard or manual transmission. It is mounted on the floor to the right of the steering wheel or directly on the steering column. Some trucks, such as semi-trucks or tractor trailers have nine or more gears, which occasionally calls for more than one shifter. Since most cars have five, there is usually only one.
Torque Converter - A torque converter is a part located near or on the crankshaft. It automates the engaging and disengaging of the transmission by redirecting the flow of fluids with a pump.
Valve Body - The valve body, or control valve assembly, is the brain of the automatic transmission, and contains many valves, passages, and solenoids. Since semi-trucks and trailers have more complex transmissions, valve bodies are typically only found in passenger trucks and cars.
Vehicles can’t run without transmissions. This is especially true of trucks and tractors, which need large, powerful transmissions to operate. The transmission is basically the mechanism in charge of transmitting power to the automobile’s wheels. If the transmission doesn’t work, then the vehicle won’t move. It’s not uncommon for the transmission to break down and require repair services.
Qualified mechanics can replace or repair transmissions. Sometimes they are salvageable and the problem simply requires a part replacement. Other times, the transmission is so far gone that only replacing the entire mechanism will do. Trucks range in size, from small pick up trucks to large cargo hauling trucks. Trucks make it easy to pick up and load items for transport from one place to another. Tractors are typically used on farms to pull agriculture implements or machinery. They can also plow and tow, and feature large back tires with heavy treads that can grip surfaces easily.
Both of these types of vehicles feature a powerful gasoline or diesel motor engine. As such, they both need a powerful transmission system to handle the loads they haul. Manufacturers make and sell transmissions for trucks and tractors. They sell to dealerships, who in turn sell to the general public, companies and truck drivers.
Mechanics who service these transmissions are usually also skilled at rebuilding both manual and automatic transmissions. Regular maintenance helps keep trucks, tractors and other autos operating at peak performance. These mechanics can also provide part replacement for turbo systems, along with repair of anything from the clutch and shift, to the gears and brakes. They use special tools to perform their jobs, rebuilding transmissions, changing brake fluid and providing repair services. They fix overdrive mechanisms, torque converters, pumps and seals. Kits may be for sale through manual transmissions dealers for the handy mechanic.
