It’s not easy to answer the question of how often to change your car’s transmission oil.

The majority of people do not know when to check the transmission fluid. The user is required to regularly consider these questions. In the long run, severe damage to the engine or transmission components may result if these intervals are missed.

Since more and more people are keeping track of how their cars are doing, it’s important to keep an eye on the important parameters of your car and the engine. The liquid that powers the engine and lubricates the transmission, allowing all of the engine’s components to move freely, is transmission fluid. The transmission oil powers and controls everything in the vehicle, from the wheel to the engine to the vehicle’s speed.

The transmission of your car can be either manual or automatic. Transmission fluid also serves as a coolant and transmits power to the engine in the case of the latter type. You will benefit greatly from having a car that has been well-maintained and will accompany you for many years. However, if you are careless, you may experience issues within the first year. So, let’s get into the subject of how often to change your car’s transmission fluid.

When to Change Your Car’s Transmission Fluid


Here are some suggestions for when to do it best. It is important to note that transmission oil replacement intervals vary by vehicle and manufacturer. Different cars from the same manufacturer may have different intervals. Whether you have a manual or automatic transmission is also a big factor.

Depending on how you drive, you could typically change the fluid in a manual vehicle every 15,000 to 20,000 kilometres. You might want to do it between 35,000 and 40,000 kilometres in an automatic version.

However, if you encounter difficulties while engaging in any of the gears, you must immediately have it checked.

When compared to an automatic transmission, a manual transmission quickly becomes contaminated and dirty, which is the reason for the early change. The system is relatively open and has many moving parts. Because everything in the automatic transmission is somewhat more sealed, there is no risk of the fluid becoming dirty. However, there are a lot of hydraulic parts that don’t need their oil changed as often.

How to Check Automatic Transmission Fluid Level?

As recommended by the manufacturer, you are required to regularly check the levels of the transmission oil in your vehicle. The dipstick that is situated next to the transmission of your vehicle can be used to measure the amount of oil in the transmission. Pay attention to the markings and look for a change in colour or the smell of burned particles.


If that is the case, you should get professional assistance to change the fluid.

In the past, transmission dipsticks were used to estimate fluid levels in automobiles; however, most current models do not include dipsticks. Because it is impossible for anyone to frequently get under the car and determine the need for a transmission fluid change, the owner must consult the vehicle’s manual for details. Keep track of the number of kilometres travelled and follow the instructions in your owner’s manual to determine when the transmission oil in your vehicle needs to be changed.

Failure of the transmission comes with a number of potential dangers.

Although transmission oil initially performed admirably as a lubricant and coolant, its use in lubricating continuously running parts and the high heat generated as a result eventually causes it to degrade. It gradually loses its lubricating properties as usage increases and its overall functional distribution across all units increases, increasing the risk of transmission failure and the severity of heat damage.
