Transmission fluid plays a crucial role in lubricating, cooling, and ensuring smooth gear changes. However, many car owners only focus on engine oil and forget about transmission fluid.

3 Golden Times for Changing Transmission Fluid – Don't Wait Until Your Car Breaks Down Before You Remember to Change It

The gearbox also needs its oil changed at the right time.Delays can lead to rapid gearbox degradation, jerky gear changes, sluggish performance, and significant repair costs. Below are some of the reasons.3 key times when you should change your transmission fluid.To protect your vehicle effectively.

 


 

1. When the vehicle reaches the manufacturer's recommended mileage.

This is the most important and easily overlooked step. Each type of transmission will have a different oil change interval:

- Automatic transmission (AT): approximately40.000 – 60.000 km
- CVT transmission: approximately40.000 km(should be replaced sooner than AT)
- Manual transmission (MT): approximately60.000 – 80.000 km
- Dual-clutch transmission (DCT): approximately40.000 – 50.000 km

After this time, the transmission fluid will degrade, reducing its lubricating and power transmission capabilities. Changing the fluid at the correct mileage intervals helps the transmission operate smoothly, extends its lifespan, and reduces wear and tear on internal components.

 


 

2. When the vehicle shows signs of abnormality.

You don't need to wait for the mileage to be reached; if your car shows the following signs, it's a "warning sign" that the transmission fluid has degraded:

- The car wasSlow accelerationThe engine revs high, but the car doesn't accelerate quickly.
- Shift gearsDelay, stuttering, or slight vibration.
- The gearbox emitsstrange howling and screeching sounds
- The transmission fluid turned dark in color and had a burnt smell upon inspection.
This is the second prime time to change the transmission fluid. If you continue using it, components such as the clutch plates, valve body, or torque converter can wear out quickly.

 


 

3. After the vehicle has operated under harsh conditions.

If the car is used frequently:

- Going to the city means going through a lot of traffic jams.
- Carrying heavy loads, climbing hills, traveling on mountain passes.
- Operating in hot or submerged environments.

 

Then the transmission fluid will degrade.Faster than standard cycleIn this case, changing the oil sooner than recommended is absolutely necessary to ensure the gearbox is always optimally protected.

 


 

Choosing high-quality transmission fluid is crucial.

Besides changing the oil at the right time, choosing the right oil is also important.high-quality gearbox oilThe lines also play a very important role.Gartz transmission fluidDeveloped to technical standards compatible with many current gearbox types:

- AT:G4, G6, 6HP, 7G, 9G-HP
- CVT: CVT RED, CVT GOLD
- MT:75W-85
- DCT:DSG, DCTF

Using the correct type of transmission fluid not only results in smoother gear changes but also reduces wear and tear, saving on long-term repair costs.
