Jaguar ATF 3403 M115

Specification JLR ATF 3403 M115 is Jaguar Land Rover’s approval for automatic transmissions, defining the requirements for viscosity, thermal stability and protective additives of transmission oil. Oil that meets this standard must have a stable viscosity in the range of 6.5–7.5 cSt at 100 °C, provide quick clutch engagement and smooth gear shifts, and also withstand the high temperatures and loads typical of turbocharged gasoline and diesel powertrains of JAGUAR and LAND ROVER, including hybrid models. The specification provides compatibility with gearboxes equipped with emission after‑treatment systems (DPF and catalysts) that require low SAPS content to prevent their fouling. Thanks to special anti‑wear and anti‑oxidant additives, ATF 3403 M115 extends filter life and reduces the risk of deposit formation in valves and hydraulic channels. Using transmission oil marked JLR ATF 3403 M115 guarantees compliance with the manufacturer’s recommendations, increased reliability and the possibility of an extended service interval for your Jaguar or Land Rover.
