Abstract
Shift characteristics, which were available from an engine dynamometer used for a new automatic transmission development, are the input to develop a method of predicting shift quality and the life of friction material of the transmission. The discriminant analysis was used for the prediction of shift quality and Miner's Law for the prediction of the friction material life. The prediction method proved effective to orienting the work to establish shift characteristics specifications in the product development stage. it allowed to considerably shorten the time required for establishing these specifications.
