What is Gartz ATF G8+?

GARTZ ATF G8+It is automatic transmission fluid.Fully Synthetic Automatic Transmission FluidDeveloped for modern automatic transmissions requiring low viscosity oil, precise friction control, and high thermal stability.

 

Unlike many traditional ATF generations, modern multi-speed automatic transmissions use a hydraulic system, clutch, and electronic control with higher precision. Therefore, the oil not only serves to lubricate but also directly participates in the process of pressure transmission, controlling friction of the clutches, and supporting the quality of gear shifting.

GARTZ ATF G8+ is developed using advanced technology.Low-Viscosity ATF, aiming for faster, more stable gear changes and reduced transmission losses in next-generation gearboxes. Gartzlube

Why do 8-speed transmissions require specialized ATF oil?

As the number of gears increases, the gearbox has to perform more clutch engagement and disengagement cycles, and the hydraulic control system must operate with greater precision.

Therefore, the oil used for these gearboxes must simultaneously maintain multiple characteristics: suitable viscosity, stable coefficient of friction, accurate pressure transmission, oxidation resistance, and protection of friction surfaces under high temperature conditions.

If the oil's viscosity or friction properties are not compatible with the gearbox design, shifting quality and clutch control can be affected.

That's why you shouldn't choose oil based solely on the question."How many gears does the gearbox have?"A more accurate way is:

Transmission code → OEM oil standard → compatible ATF product.

Advantages of Gartz ATF G8+

GARTZ ATF G8+ is designed for modern automatic transmissions with the following key characteristics:

Low-Viscosity ATF:It facilitates rapid oil circulation and reduces hydraulic losses.

Precise friction control:The clutch provides stable opening and closing support and smooth gear changes.

Thermal stability and antioxidant properties:This helps to minimize oil degradation when the transmission operates at high temperatures.

 

Wear resistance:Protect gears, clutches, oil pumps, and load-bearing surfaces.

Sediment control:It helps maintain the cleanliness of the valve body and hydraulic system.

Fully Synthetic:Maintains performance over a wide operating temperature range. Gartzlube

GARTZ ATF G8+ composition

According to GARTZ's current technical information, ATF G8+ is formulated from high-quality synthetic base oils combined with a specialized additive system.

The formula is optimized for gearboxes that require it.Low-Viscosity Automatic Transmission Fluid. Gartzlube

Which transmissions are compatible with GARTZ ATF G8+?

ATF G8+ should not be selected simply based on vehicle brand. The product must be matched against the correct oil standard and transmission code.

According to the GARTZ application catalog currently available, the G8+ is geared towards a wide range of transmission systems from Toyota, Lexus, Aisin, BMW, Jaguar, Land Rover, GM, Ford, and several other manufacturers. Gartzlube

This is The requirements/reference applications are published by GARTZ.It should not be assumed that all vehicles from these brands use the same type of oil. It is necessary to check the exact vehicle model, transmission code, and request the OEM specifications before changing the oil. Gartzlube

GARTZ G8+ and Aisin 8-speed gearbox

One of the notable applications of the GARTZ ATF G8+ is its new generation Aisin automatic transmission.

Gearboxes such asTG-81SC and TG-81SDUsing multi-stage transmission technology with high viscosity and friction characteristics requirements for ATF oil, GARTZ lists these Aisin/Toyota-Lexus applications in the G8+ compatibility group. Gartzlube

 

For garages, here's an important point to note: don't assume that just because you see an Aisin transmission, you can use a universal ATF (Automatic Transmission Fluid) system.

Aisin has many different generations of gearboxes, and the oil requirements vary depending on the design.

Therefore, it is necessary to identify correctly.model transmissionThen, compare it to the oil standards.

Is GARTZ ATF G8+ suitable for Toyota and Lexus vehicles?

There are Toyota and Lexus applications that GARTZ has included in the ATF G8+ requirements table.

This includesToyota JWS 3324and some gearboxes belonging to the groupTG-81SC, TG-81SD, UA80E and UA80F. Gartzlube

However, Toyota and Lexus use many different types of transmissions across generations of vehicles.

Therefore, the following formula should not be applied:

"Toyota 8-speed = G8+."

Instead, it should be determined:

VIN → vehicle year → transmission code → oil requirement → compare with GARTZ G8+.

Is the Gartz ATF G8+ suitable for BMW vehicles?

GARTZ's application table currently lists BMW references:

BMW 83 22 2 152 426
BMW 83 22 2 289 720 – ATF 3+ Gartzlube

Because BMW uses many different types of transmissions, including various generations of ZF and Aisin, the choice of ATF should not be based solely on the BMW brand or the number of gears in the transmission.

The garage needs to be precisely identified.actual gearbox codebefore proceeding with the oil change.

Why is low viscosity important for modern gearboxes?

The next-generation automatic transmission is optimized to reduce energy loss and improve transmission efficiency.

A suitable low-viscosity ATF allows the oil to move quickly through narrow oil passages, supporting the responsiveness of the valve body and solenoid system, while reducing hydraulic resistance.

However, Low Viscosity doesn't mean the more diluted, the better..

The oil must maintain a sufficiently strong lubricating film at high temperatures and keep the friction coefficient correct for the clutch design.

That is why the choice of ATF must be based onOEM standard, not just based on viscosity index.

When should you check your transmission fluid?

Over time, ATF (Automatic Tissue Fluid) is subjected to heat, shear forces, and wear deposits generated by the clutch and other mechanical parts.

If your vehicle starts experiencing issues such as rough gear changes, slow D/R engagement, vibrations, delayed shifting, or a burnt smell from the oil, you should check the oil and transmission system.

These symptoms don't necessarily mean that simply changing the oil will fix the problem. For vehicles with clear symptoms, it's necessary to check the fault codes, oil level, live data, oil pressure, and mechanical condition before proposing any repairs.

GARTZ supplies oil for a wide variety of gearboxes.

GARTZ does not develop one type of oil for use in all transmissions.

The current range of transmission fluids is divided by technology as follows:ATF is for automatic transmissions with gears, CVTF for CVT transmissions, DCTF/DSG Fluid for dual-clutch transmissions, and MTF for manual transmissions.The GARTZ product line currently includes ATF G8+, G6, 6HP, ATF G4, 7G-Tronic, 9G-HP, CVT RED, CVT GOLD, DCTF, DSG Fluid, and MT 75W85. Gartzlube

This helps garages and users choose products based on...Gearbox technology and actual specificationsInstead of using one type of all-purpose oil for all vehicles.

GARTZ transmission fluid quick classification

The actual list needs to be further compared according to the oil requirements of each transmission. Gartzlube

GARTZ – Choose the right oil for your transmission, not just by the car model.

The vehicle's make and model isn't the only information needed to choose transmission fluid.

A car model may be equipped with various types of transmissions depending on the year of manufacture, engine, market, and version.

The correct selection process should always follow this order:

Vehicle → VIN → Transmission code → OEM standard → Compatible oil products.

This is also the direction of the GARTZ product line: dividing oils by transmission group to make selection clearer and reduce the risk of using the wrong oil. Gartzlube
