Bridging the Gap Between DEXRON®-II and Type F ATF

An automatic transmission fluid has been developed which can meet the needs of transmissions designed for either friction modified or non-friction modified fluids. Approved under the DEXR0N*-II and M2C138-CJ specifications, it also meets all the requirements of the M2C33-F (Type F) specification except for the friction modifier content. Since use of a friction modified fluid in Type F applications would represent a radical departure from current recommended practice, data, both pro and con, on the concept are presented.
