What Is LIQUI MOLY Top Tec ATF 1900?

LIQUI MOLY Top Tec ATF 1900 is a fully synthetic, low-viscosity automatic transmission fluid developed for compatible Mercedes-Benz 7-speed automatic transmissions. It is formulated to meet the requirements of transmissions that specify MB 236.15 fluid, including selected Mercedes-Benz 722.9 and 724.2 hybrid applications. Its advanced formulation is designed to support efficient transmission operation, consistent friction characteristics and dependable performance across different operating temperatures.

Automatic transmission fluid is an important part of the transmission system. It lubricates internal components, helps manage friction between moving parts and supports the hydraulic operation required for gear changes. Using the correct ATF specification is essential because modern automatic transmissions are designed around particular fluid characteristics. The wrong fluid can affect shifting behaviour and may not provide the performance required by the transmission manufacturer.

Designed for Compatible Mercedes-Benz Automatic Transmissions

LIQUI MOLY Top Tec ATF 1900 has been developed for specific Mercedes-Benz 7-speed automatic transmissions, particularly the 722.9 and 724.2 hybrid transmission types where MB 236.15 is required. It is intended for applications that call for this particular low-viscosity ATF specification.

The product is not a universal automatic transmission fluid. Mercedes-Benz vehicles can use different automatic transmission designs and fluid requirements depending on the model, production date, engine and gearbox version. Even vehicles from the same model range may require different ATF specifications. For this reason, always check the vehicle handbook, transmission identification and manufacturer service information before selecting the fluid.

Low-Viscosity Formulation for Efficient Operation

One of the main characteristics of LIQUI MOLY Top Tec ATF 1900 is its low-viscosity formulation. The fluid is designed to provide suitable flow characteristics while helping the transmission operate efficiently. LIQUI MOLY highlights its viscosity-temperature behaviour and high efficiency as important product properties.

The formulation is also designed to maintain stable friction characteristics. Friction behaviour is particularly important in automatic transmissions because the fluid works with internal friction elements and hydraulic control systems during gear changes. A fluid with characteristics matched to the transmission’s requirements helps support consistent operation.

Friction Performance and Transmission Protection

Automatic transmissions contain numerous precision components that operate together. The transmission fluid helps lubricate internal parts and supports the friction characteristics required by the gearbox. LIQUI MOLY Top Tec ATF 1900 is formulated with modern additive components to provide outstanding friction characteristics and stable performance.

Correct fluid selection is especially important for transmissions that require MB 236.15. Using a fluid with a different specification simply because it is also an automatic transmission oil is not recommended. Always follow the transmission manufacturer’s instructions and use the exact fluid specification required for the application.

Very Good Low-Temperature Properties

Transmission fluid must perform under changing temperature conditions. During cold starts, the fluid needs suitable flow properties, while during normal operation it must maintain characteristics appropriate for the transmission. LIQUI MOLY lists very good low-temperature properties and excellent viscosity-temperature behaviour among the features of Top Tec ATF 1900.

These characteristics make the product suitable for the applications specified by the manufacturer. The fluid’s performance should not, however, be treated as permission to use it in every automatic gearbox. The required transmission specification remains the most important selection factor.

Technical Specifications

Important Application Instructions

Before purchasing or filling LIQUI MOLY Top Tec ATF 1900, confirm that the vehicle or transmission specifically requires MB 236.15. Do not select the product based only on the vehicle brand, model name or number of transmission gears. Check the exact gearbox code and the manufacturer’s fluid requirement.

LIQUI MOLY advises following the specifications and instructions provided by the vehicle or transmission manufacturer. The product should not be mixed with oils of other specifications. For a transmission service, use the correct filling procedure, fluid level-checking temperature and service instructions for the particular gearbox. The quantity required will depend on the transmission and whether the service involves a drain-and-fill or a more extensive fluid replacement.
