Abstract
The development of new automatic transmission designs, the new quality requirements as well as the extended lubricant life have an influence on the constant development of new lubricant formulations for automatic transmission fluids. Their reological properties matter a lot in meeting those requirements. The kinematic viscosity at high and low temperatures is a very important lubricating oil characteristic, which needs to be retained within the certain values during its lifetime. The elastohydrodynamic lubricating film needs to be maintained along the whole range of operating temperatures. When using it at low temperatures gear change needs to be easy.
The paper presents how to meet performance requirements in regard with the specifications by the proper selection of base components conforming ATF DEXRON III formulations.
