Anti-shudder properties of automatic transmission fluids

摘要

In recent years, the slip lock-up clutch system has been adopted widely because of its enhanced fuel efficiency. For such a transmission to functionproperly, the working fluid must exhibit friction properties within a narrow range. Various tests, both laboratory and vehicle, have been devleoped by automobile and transmission manufacturers to evaluate these fluids. A sub-committee of the International Lubricant Standardization of Approval Committee (ILSAC) has evaluated test methods and has reported its results ina paper, "nti-shudder Property of Automatic Transmission Fluids-A Study by the ILSAC ATF Subcommittee," (SAE 2000-01-1870)by Y.Murakami of Nissan and nine other authors. The authors represent General Motors, Ford, Daimler-Chrysler and the major Japanese autompbile companies.
