Different Types of Car Transmission Fluid

What is Transmission Fluid?

Transmission fluid is a type of lubricant that is used to lubricate the gears and other moving parts of a car’s transmission. It helps to reduce friction and wear, and it also helps to cool the transmission. Transmission fluid is typically made from a base oil, such as mineral oil or synthetic oil, and it contains a variety of additives to improve its performance.

Types of Transmission Fluid

There are several different types of transmission fluid, each of which is designed for a specific type of transmission.

Manual Transmission Fluid

Manual transmission fluid is used in manual transmissions, which are typically found in older cars and trucks. Manual transmission fluid is typically a heavier-weight oil than automatic transmission fluid, and it contains additives that help to prevent wear and tear on the gears.

Automatic Transmission Fluid

Automatic transmission fluid is used in automatic transmissions, which are typically found in newer cars and trucks. Automatic transmission fluid is typically a lighter-weight oil than manual transmission fluid, and it contains additives that help to smooth the shifting process.

CVT Fluid

CVT fluid is used in continuously variable transmissions (CVTs), which are becoming increasingly popular in newer vehicles. CVT fluid is typically a very light-weight oil, and it contains additives that help to protect the CVT’s belts and pulleys.

Dual-Clutch Transmission Fluid

Dual-clutch transmission fluid is used in dual-clutch transmissions (DCTs), which are a type of automated manual transmission. DCT fluid is typically a very high-performance oil, and it contains additives that help to protect the DCT’s clutches and gears.

Transmission Fluid Maintenance

Transmission fluid should be changed regularly to ensure that it is clean and free of contaminants. The frequency of transmission fluid changes will vary depending on the type of transmission and the vehicle’s driving conditions. However, most manufacturers recommend changing the transmission fluid every 30,000 to 60,000 miles.
