Changing Transmission Fluid in Older Cars

Transmission fluid is an essential part of your car’s drivetrain. It helps to lubricate the gears and other moving parts of the transmission, which keeps it running smoothly. Over time, transmission fluid can break down and become contaminated with dirt and metal shavings. This can lead to transmission problems, such as slipping gears or difficulty shifting. You may also notice a decrease in fuel efficiency if your transmission fluid is not properly maintained.

Why is it important to change transmission fluid in older cars?

Transmission fluid is essential for the proper functioning of your car’s transmission. It helps to reduce friction between moving parts, preventing premature wear and tear. Transmission fluid also serves as a cooling agent, helping to disperse heat away from the transmission’s components. As your car ages, the transmission fluid can become contaminated with dirt, metal shavings, and other debris. This can lead to decreased transmission performance and, eventually, transmission failure. Changing the transmission fluid regularly helps to flush out these contaminants and keep your transmission running smoothly.

How often should you change transmission fluid in an older car?

The frequency of transmission fluid changes depends on a number of factors, including the age of your car, the type of transmission it has, and how often you drive. In general, it is recommended to change the transmission fluid every 30,000 to 60,000 miles. However, if you frequently tow heavy loads or drive your car in extreme conditions, you may need to change the transmission fluid more often.

What are the signs that you need to change transmission fluid?

There are a few signs that may indicate that you need to change the transmission fluid. These include:

• Slipping gears
• Difficulty shifting
• Noisy transmission
• Burning smell
• Decreased fuel efficiency

How to change transmission fluid in an older car
