What type of transmission fluid does the Kia Seltos use?

The Kia Seltos is one of the most popular urban SUVs in Vietnam; however, not all Seltos versions use the same transmission.

Depending on the model year, engine, and distribution market, the Kia Seltos may use different types of transmissions, such as:

6-speed automatic transmission (6AT)

7-speed dual-clutch transmission (7DCT)

Some markets use CVT transmissions.

Therefore, the question"What type of transmission fluid does the Kia Seltos use?"It's impossible to answer with just one type of oil.

The choice of transmission fluid should be based on:

Vehicle version

Gearbox type

Manufacturer's oil specifications

Actual operating conditions

Using the wrong type of oil can affect gear shifting ability, thermal stability, and the lifespan of internal transmission components.

What types of transmissions does the Kia Seltos use?

Kia Seltos 6AT automatic transmission

Some versions of the Kia Seltos use a traditional 6-speed automatic transmission.

This is a type of transmission with a torque converter, which uses ATF oil to:

Lubricate the gears.

Hydraulic pressure transmission

Cool the internal clutch assembly.

Assisting with the gear shifting process.

With a 6AT transmission, the oil needs to have suitable friction properties for the clutch and hydraulic system to operate smoothly.

When choosing oil for the Seltos 6AT, it's essential to check that it meets Kia's specific standards, rather than simply selecting oil labeled "ATF for Korean cars."

What type of oil does the Kia Seltos 7DCT use?

Some versions of the Kia Seltos use a 7-speed dual-clutch transmission (7DCT).

Unlike traditional automatic transmissions, DCT uses two clutches to control odd and even gears.

This structure helps to:

Faster gear shifting

Increase transmission efficiency

Improve fuel efficiency

However, DCT transmissions require a specific type of oil.

DCT oil not only lubricates gears but must also be suitable for:

Dual clutch mechanism

Internal drive

Friction control capability

Therefore, regular ATF oil should not be used in DCT transmissions without confirmation from the manufacturer.

What type of oil does the Kia Seltos CVT use?

Some markets or versions of the Kia Seltos use a CVT transmission.

Unlike automatic transmissions with fixed gears, CVTs use a system of pulleys and metal belts/chains to continuously change the gear ratios.

Therefore, CVT oil needs to have:

Specific friction characteristics

Belt abrasion resistance

High thermal stability

CVT oil and conventional ATF oil should not be used interchangeably.

A vehicle using a CVT requires the correct type of CVT fluid as specified in the technical specifications.

Why shouldn't you choose Kia Seltos transmission fluid based solely on the car's name?

 

A common mistake is thinking that:

"The Kia Seltos uses the same type of transmission fluid."

In fact, even the same car model can have completely different versions using different transmissions.

For example:

Therefore, choosing the right oil should start with the transmission, not the car model.

Signs that your Kia Seltos needs a transmission fluid check.

Gearbox oil operates in high-temperature and high-pressure environments. After prolonged use, the oil may experience the following:

Oxidation

Reduced lubrication

Change the friction characteristics

Metal mite infestation

Some signs to check for:

The gear shifting is jerky.

The car has a delay when shifting to D or R.

The engine speed increased, but the car accelerated slowly.

The gearbox is overheating abnormally.

Howling or strange noises

However, these symptoms don't just come from the transmission fluid; they could be related to many other components. A thorough diagnosis is necessary before replacement.

How often should I change the transmission fluid in a Kia Seltos?

The transmission fluid change interval depends on:

Gearbox type

Operating conditions

Usage environment

Manufacturer's recommendation

If the car is used frequently:

Walking through the crowded streets

Traffic jam

Transport

Run on the hot road.

Then the transmission fluid may degrade more quickly.

Regular inspections help detect oil conditions early and limit transmission-related problems.

Mistakes to avoid when choosing Kia Seltos transmission fluid.

Use ATF oil for all types of transmissions.

ATF is only compatible with certain traditional automatic transmissions.

Not all transmissions in the Seltos use ATF.

Choose oil according to the car brand.

Many people choose oil simply because they see "Kia/Hyundai" written on the label.

However, new technical standards are the crucial factor.

Thinking that higher-grade oil will always be better.

The best oil isn't necessarily the most expensive.

The most suitable oil is the oil that meets the specific requirements of the gearbox.

Conclusion: What type of transmission fluid does the Kia Seltos use?

The Kia Seltos does not have a single type of transmission fluid that is common to all versions.

Depending on the configuration:

The Seltos 6AT requires the correct ATF oil standard, such as ATF G6.Gartz

Seltos 7DCT requires specialized DCTF DCT oil.Gartz

Seltos CVT requires the appropriate CVT oil, CVT RED/GOLD.Gartz

When changing the transmission fluid in a Kia Seltos, check the following:

Vehicle model → Version → Transmission type → Oil standard.

Choosing the right oil not only helps the gearbox run more smoothly but also contributes to maintaining the durability of the drivetrain during use.
