Transmission Fluid for Automatic Cars: A Comprehensive Guide
What is Transmission Fluid?
Transmission fluid is a type of hydraulic fluid that is used in automatic transmissions to lubricate and cool the transmission components. It helps to reduce friction between the moving parts and prevents wear and tear. Transmission fluid also helps to transfer power from the engine to the wheels.
Types of Transmission Fluid
There are several different types of transmission fluid available, each with its own unique properties. The most common type of transmission fluid is ATF, or automatic transmission fluid. ATF is designed for use in automatic transmissions and is available in a variety of viscosities. Other types of transmission fluid include CVT fluid, manual transmission fluid, and dual-clutch transmission fluid.
ATF
ATF is the most common type of transmission fluid and is used in most automatic transmissions. It is available in a variety of viscosities, from low-viscosity fluids for use in cold climates to high-viscosity fluids for use in hot climates. ATF is typically red or amber in color.
CVT Fluid
CVT fluid is used in continuously variable transmissions (CVTs). CVTs are a type of automatic transmission that uses a belt or chain to transfer power from the engine to the wheels. CVT fluid is designed to lubricate the belt or chain and prevent wear and tear. CVT fluid is typically green or blue in color.
Manual Transmission Fluid
Manual transmission fluid is used in manual transmissions. Manual transmissions are a type of transmission that uses a clutch to transfer power from the engine to the wheels. Manual transmission fluid is designed to lubricate the gears and prevent wear and tear. Manual transmission fluid is typically amber or brown in color.
Dual-Clutch Transmission Fluid
Dual-clutch transmission fluid is used in dual-clutch transmissions (DCTs). DCTs are a type of automatic transmission that uses two clutches to transfer power from the engine to the wheels. Dual-clutch transmission fluid is designed to lubricate the clutches and prevent wear and tear. Dual-clutch transmission fluid is typically red or amber in color.
When to Change Transmission Fluid
The recommended interval for changing transmission fluid varies depending on the type of transmission and the driving conditions. However, most manufacturers recommend changing the transmission fluid every 30,000 to 60,000 miles.
If you experience any of the following symptoms, it may be a sign that your transmission fluid needs to be changed:
- Slipping gears
- Hesitation when shifting gears
- Noisy transmission
- Leaking transmission fluid
- Burnt smell coming from the transmission
How to Change Transmission Fluid
Changing transmission fluid is a relatively simple process, but it is important to follow the manufacturer’s instructions carefully. Here are the general steps involved in changing transmission fluid:
- Gather your tools and materials. You will need a new transmission filter, transmission fluid, a funnel, and a wrench.
- Locate the transmission pan. The transmission pan is usually located at the bottom of the transmission.
- Drain the old transmission fluid. Place a drain pan under the transmission pan and loosen the drain plug. Allow the old transmission fluid to drain out completely.
- Replace the transmission filter. Remove the old transmission filter and replace it with a new one.
- Reinstall the transmission pan. Tighten the drain plug and reinstall the transmission pan.
- Add new transmission fluid. Use a funnel to add new transmission fluid to
