Auto Transmission Car Maintenance
What is an Automatic Transmission?
An automatic transmission is a type of gearbox that automatically changes gears as the car’s speed changes. This is in contrast to a manual transmission, which requires the driver to manually shift gears. Automatic transmissions are more convenient and easier to drive than manual transmissions, which is why they are more popular in modern cars.
How Does an Automatic Transmission Work?
An automatic transmission uses a combination of gears, clutches, and hydraulic pressure to change gears. When the car is stopped, the transmission is in neutral. When the driver steps on the gas pedal, the transmission shifts into first gear. As the car accelerates, the transmission shifts into higher gears. When the car is slowing down, the transmission shifts into lower gears.
Types of Automatic Transmissions
There are several different types of automatic transmissions, including:
- Conventional automatic transmissions are the most common type of automatic transmission. They use a planetary gearset to change gears.
- Continuously variable transmissions (CVTs) use a belt or chain to change gears. CVTs are more efficient than conventional automatic transmissions, but they are also more expensive.
- Dual-clutch transmissions (DCTs) use two clutches to change gears. DCTs are more responsive than conventional automatic transmissions, but they are also more complex.
Auto Transmission Car Maintenance
Automatic transmissions require regular maintenance to keep them in good working order. This maintenance includes:
- Checking the transmission fluid level. The transmission fluid level should be checked every 30,000 miles or so. If the fluid level is low, it should be topped off.
- Changing the transmission fluid. The transmission fluid should be changed every 60,000 miles or so. This will help to keep the transmission clean and free of debris.
- Inspecting the transmission filter. The transmission filter should be inspected every 30,000 miles or so. If the filter is dirty, it should be replaced.
- Servicing the transmission solenoids. The transmission solenoids control the flow of fluid in the transmission. They should be serviced every 60,000 miles or so.
Signs of Auto Transmission Problems
There are several signs that your automatic transmission may be having problems, including:
- Slipping gears. If your transmission is slipping gears, it will not be able to properly transfer power from the engine to the wheels. This can cause the car to hesitate or jerk when you accelerate.
- Hard shifting. If your transmission is hard shifting, it will be difficult to shift gears. This can be caused by a number of problems, including low transmission fluid, dirty transmission fluid, or worn transmission parts.
- Leaking transmission fluid. If your transmission is leaking fluid, it will need to be repaired as soon as possible. Transmission fluid is essential for the proper operation of the transmission, and a leak can cause the transmission to fail.
Auto Transmission Repair
If your automatic transmission is having problems, it is important to have it repaired by a qualified mechanic. Transmission repair can be complex and expensive, so it is important to find a mechanic who is experienced in repairing automatic transmissions.
Conclusion
Automatic transmissions are complex and important components of modern cars. They require regular maintenance to keep them in good working order. If your transmission is having problems, it is important to have it repaired by a qualified mechanic.
