Development of a multi-purpose ATF meeting DEXRON®III, MERCON® and JASO M315 specifications

Yoshie Arakawa; Rika Yauchibara; Yasuhiro Murakami

An additive package for the automatic transmission fluid (ATF) used in slip lockup control automatic transmissions has been developed that satisfies all the requirements of the DEXRON® III, MERCON® and JASO M315 specifications. The influence of the base oil and viscosity index improver that are combined with this additive package was also investigated with respect to ATF performance.
