100% synthetic transmission oil. This oil with excellent properties and low viscosity has been specially developed for most modern. heavy-duty trucks and buses with or without automatic transmissions (manual shift. sequential shift. electronic control, etc.). MOTUL ATF HD is an extended drain oil. designed for the most severe driving conditions and fully adapted to frequent stop-start operation. The special special formulation of this lubricant protects compact and heavily loaded gears thanks to its improved wear protection properties. Extends the service life of the transmission thanks to its high shear strength at high temperatures and oxidation resistance. Motul ATF HD ensures fuel economy in vehicles with automatic transmission. by reducing friction in planetary gears and improving the response speed of the automatic transmission at low temperatures. The lubricant contains anti-corrosion and anti-foaming agents. It has vibration-reducing properties and prevents engine flywheel vibration. The use of the product ensures smooth gear changes and minimizes shift delay. ensuring the best responsiveness of the automatic transmission.
