9G SYNTRO ATF

AUTOMATIC TRANSMISSION FLUID

Designed to be used in Mercedes-Benz 9G-Tronic
725.0 and mb 236.17 Transmissions

Low-viscosity blend of special synthetic base oils of the highest quality with a consistently high viscosity index with a multifunctional additive package retains all its properties over a wide range of temperatures and loads.

The high-technology combination of additives ensures excellent antifriction properties for gear couplings and superior friction properties for friction elements thus ensuring a significant fuel economy, a continuous, exact, and smooth transmission shift in any driving conditions and an extended service life of the automatic gearbox itself and all transmission elements. It ensures a coordinated and smooth operation of clutches. It prevents scuffing. It allows reducing lacquering and formation of sludge. soot and other carbon deposits, increasing the time between oil changes and ensuring the durability of transmission components thus reducing the equipment maintenance costs.

1. Smooth and Fast Shift Response

∙ Precisely tuned viscosity for the 9G-Tronic system
∙ Excellent low-temperature flow for smooth shifts from cold start
∙ Reduced slip for improved acceleration and responsiveness

2. Enhanced Anti-Wear Protection

∙ Strong anti-wear additives protect gears, bearings, and clutch packs
∙ Prevents scuffing and metal-to-metal wear
∙ Maintains smooth shifting even over extended use

3.High Thermal Stability Synthetic Base Oil

∙ Exceptional oxidation resistance minimizes viscosity breakdown
∙ Stable performance under long-distance and high-load driving
∙ Keeps valve body and hydraulic components clean and responsive

4. Sludge and Deposit Control

∙ Effectively suppresses sludge, varnish, and deposits
∙ Reduces risk of hydraulic circuit malfunction
∙ Maintains clean system condition throughout the service interval

5. Optimized for 9-Speed Performance

∙ Optimized friction characteristics reduce energy loss
∙ Improved torque converter lock-up stability
∙ Provides refined shift quality, reduced vibration, and better fuel efficiency
