What type of transmission fluid does the Ford Ranger use? Differentiating between 6AT, 10AT, and specific model years.

What type of transmission fluid does the Ford Ranger use?

Not all generations and versions of the Ford Ranger use the same type of automatic transmission.

In Vietnam, the Ranger has gone through several phases using 6-speed and 10-speed automatic transmissions. Even within the same generation, the type of transmission can vary depending on the engine, version, and year of manufacture.

This means that the question "What type of transmission fluid does the Ford Ranger use?" should not be answered simply with a product name.

A more accurate way to determine this is:

Vehicle model → version → transmission type → transmission code → oil standard.

A key point to note is that the two common transmissions on the Ranger have very different oil requirements:

Gearbox6R80 6-speedFord mandates that the oil meets the required standards.WSS-M2C938-A / MERCON LV.

Gearbox10R80 10-speedFord mandates that the oil meets the required standards.WSS-M2C949-A / MERCON ULV. citeturn892627search0turn892627search1

Therefore, the oils used for Ranger 6AT and 10AT are not interchangeable.

What type of transmission fluid does the older Ford Ranger 6AT use?

On many previous generation Ford Ranger T6 models, the 6-speed 6R80 automatic transmission was quite commonly used.

Ford's official technical documentation for the Ranger specifies that the 6R80 transmission uses standard-compliant oil.WSS-M2C938-A, corresponding toMERCON LV. citeturn892627search4turn892627search8

This is a more important factor than simply looking at the number of gears in the gearbox.

A product advertised as "6-grade oil" may not necessarily be suitable. What needs to be checked is whether the product actually meets the standards required by Ford.

Which GARTZ model would be suitable for the Ranger 6R80?

For the Ranger using 6R80, the garage should still check the vehicle's specifications, transmission code, and technical documentation before deciding on a product.

When did the Ranger 10AT first appear?

2018 was a significant year for the Ford Ranger in Vietnam.

Ford Vietnam then introduced the new Ranger with a 2.0L Bi-Turbo Diesel engine paired with a 10-speed automatic transmission. Ford also described this as the first time a 10-speed transmission appeared on the Bi-Turbo Ranger and Everest models in Vietnam.

However, this does not mean that "all Ranger models from 2018 onwards are 10AT".

For many years afterward, the 6AT and 10AT configurations continued to exist side-by-side, depending on the version.

For example, Ford Vietnam's specifications page for the 2024 Ranger Sport indicates that the 2.0L Turbo Diesel version uses...6-speed automatic transmission. citeturn964146search2

Therefore, the year of manufacture is only initial reference data. The year of the vehicle should not be used as the sole factor in choosing oil.

What type of transmission fluid does the Ford Ranger 10AT use?

For Ranger models using a gearbox10R80, requires a significantly different oil compared to 6R80.

According to the Ford Ranger manual, the 10R80 transmission uses the following type of fluid:

WSS-M2C949-A / MERCON ULV

Ford also notes that transmissions requiring MERCON ULV should only use fluids that meet this standard; using other types of fluid may damage the transmission.

Here's why you shouldn't jump to conclusions:

"For a Ranger 10-speed, just use ATF oil designed for 10-speed transmissions."

The number of gears in the gearbox is not standard oil.

With 10R80, the key factor to look for in the product specifications is:WSS-M2C949-A or MERCON ULV.

Are MERCON LV and MERCON ULV the same?

Are not.

MERCON LV and MERCON ULV are two different technical requirements.

Ford has determined:

ULV stands for Ultra Low Viscosity. This type of oil is designed for the specific operating requirements of next-generation transmissions such as the 10R80.

Therefore, a product that meets MERCON LV should not automatically be considered equivalent to MERCON ULV.

This is also one of the points that needs special attention when servicing the Ranger, which has upgraded from the 6AT to the 10AT generation.

Can GARTZ ATF G6 be used for a Ford Ranger 10AT?

GARTZ ATF G6GARTZ currently offers this option for 6, 8, and 10-speed automatic transmissions, and the product page mentions Ford applications.
