Your vehicle’s transmission is responsible for transferring power from the engine to the wheels, and it is one of the most important and complex components of your car. Over time, transmission fluid can become contaminated with debris, dirt, and other impurities, which can cause it to break down and lose its lubricating and cooling properties. This is why transmission service, including regular flushing of the transmission fluid, is essential to ensure the longevity and optimal performance of your vehicle.

What is Transmission Fluid?
Transmission fluid is a specialized lubricant that is designed to perform several critical functions in your vehicle’s transmission system. Its primary role is to lubricate and cool the various moving components of the transmission, such as gears, bearings, and shafts. Transmission fluid also helps to maintain hydraulic pressure within the transmission, which is necessary for proper shifting.
There are two main types of transmission fluid: automatic transmission fluid (ATF) and manual transmission fluid (MTF). Automatic transmission fluid is used in vehicles with automatic transmissions, while manual transmission fluid is used in cars with manual transmissions. Both types of transmission fluid are formulated with specific additives and detergents to ensure that they provide optimal performance and protection for the transmission.
Don’t Forget the Filter
In addition to changing the transmission fluid, another critical component of transmission service is changing the automatic transmission filter. The automatic transmission filter is responsible for removing contaminants and debris from the transmission fluid as it circulates through the system.
Over time, the filter can become clogged with debris, which can restrict the flow of fluid and cause transmission problems. A clogged filter can also cause the transmission to overheat, leading to more significant problems and potentially even transmission failure.
Most manufacturers recommend changing the automatic transmission filter every 30,000 to 60,000 miles, depending on the make and model of your vehicle. Some newer vehicles have longer service intervals for the transmission filter, while some older vehicles may require more frequent changes.
When you have the transmission fluid changed, it’s a good idea to have the automatic transmission filter changed as well. This can help ensure that the transmission fluid is flowing properly through the system and that your transmission is receiving the lubrication and cooling it needs to operate efficiently.

Which Transmission Fluid to Get?
Choosing the right transmission fluid for your car is essential to ensure that your transmission operates efficiently and performs at its best. Here are some steps you can take to choose the right transmission fluid for your vehicle:
Check Your Vehicle Owner’s Manual
Your vehicle owner’s manual will provide specific information about the type of transmission fluid that is recommended for your vehicle. It will also provide guidance on the recommended service intervals and other maintenance recommendations.
Check the Viscosity
The viscosity of the transmission fluid is another important consideration. The viscosity refers to the thickness of the fluid and its ability to flow through the transmission. Using a fluid with the wrong viscosity can cause shifting problems and other transmission issues. Check your owner’s manual for the recommended viscosity range.
Be Mindful of Additives
Some transmission fluids contain additives that can improve performance or provide additional benefits. However, not all additives are suitable for all vehicles, so it’s essential to choose a transmission fluid that is compatible with your vehicle and its specific needs.
Why is Transmission Service Important?

Your vehicle’s transmission is a complex and intricate system that requires regular maintenance to perform at its best. Neglecting transmission service can lead to significant problems that can be costly to repair. Here are some of the reasons why transmission maintenance is essential:
Prevents Transmission Failure
Over time, transmission fluid can become contaminated with debris, dirt, and other impurities, which can cause it to break down and lose its lubricating and cooling properties. This can lead to serious transmission problems, such as slipping gears, difficulty shifting, and even transmission failure. Regular service, such as fluid changes and inspections, can help prevent these issues.
Extends Transmission Life
By regularly maintaining your transmission, you can help extend its life and avoid costly repairs. Flushing the transmission fluid at the recommended intervals can help remove the old, dirty fluid, and replace it with clean, fresh fluid that provides optimal protection for the transmission.
Improves Transmission Performance
A well-maintained transmission can perform more efficiently, resulting in better fuel economy and smoother shifting. Regular maintenance can help ensure that your transmission is operating at peak performance.
How Often Should You Flush the Transmission Fluid?
The frequency of transmission fluid changes or flushes depends on several factors, such as the make and model of your vehicle, your driving habits, and the conditions in which you drive. In general, most manufacturers recommend flushing the transmission fluid every 30,000 to 60,000 miles. However, some newer vehicles may have longer service intervals, while some older cars may require more frequent fluid changes.
It’s essential to follow your vehicle’s maintenance schedule and get the transmission fluid changed according to the recommended intervals. Neglecting to change the transmission fluid can lead to serious transmission problems, such as slipping gears, difficulty shifting, and transmission failure.
If you notice any signs of transmission problems, such as slipping gears, difficulty shifting, or unusual noises, you should have your transmission inspected by a professional mechanic. In some cases, transmission problems can be resolved with a simple fluid change, while in other cases, more extensive repairs may be necessary.
