RAVENOL ATF T-ULV Fluid is a fully synthetic ATF (Automatic Transmission Fluid), designed on the basis of high quality polyalphaolefin (PAO) and Esters with a special additive and inhibition, which ensure a perfect function of the automatic transmission. RAVENOL ATF T-ULV Fluid is an ATF for the latest generation of Aisin Warner automatic transmissions. It guarantees a high wear protection in all operating conditions. RAVENOL ATF T-ULV Fluid has a red colour.
Reducing loss torque in automatic transmissions (ATFs) is a key factor in improving fuel economy. A promising approach is to reduce the viscosity of the Automatic Transmission Fluid (ATF) to minimize churning loss. RAVENOL has developed an ultra-low viscosity ATF, called “T-ULV”, which has approximately 50% lower kinematic viscosity at 40 °C compared to the conventional low viscosity ATFs. It is generally understood that if the viscosity of an ATF is too low, it can have a negative impact on the fatigue life of components such as gears and bearings, and possibly lead to increased wear or seizure. RAVENOL ATF T-ULV Fluid was designed to solve these problems via the application of two key technologies. The first is a high performance PAO (Polyalphaolefin) with a low traction coefficient, which translates to low viscosity under high pressure conditions. This decreases the shear resistance between sliding surfaces under elasto-hydrodynamic lubrication (EHL) conditions, which contributes to improving the fatigue life of bearings and other components. The second is an ester type base oil with high polarity. It was found that the amount of ester base oil used has a major influence on fatigue life. The adsorption of esters onto metal surfaces is thought to improve lubricity in severe lubrication conditions. Durability tests were performed in a wide range of conditions, using gear and bearing components and actual transmission units, and it was confirmed that RAVENOL ATF T-ULV Fluid outperforms low viscosity ATFs, despite its ultra-low viscosity. Furthermore, RAVENOL ATF T-ULV Fluid reduces loss torque in the transmission by approximately 12% compared to other low viscosity ATFs.
RAVENOL ATF T-ULV Fluid is an Ultra Low Viscosity ATF for modern 8-Speed automatic transmissions of Aisin Warner.
