There is a constant need for weight reduction and miniaturisation of automatic transmissions for passenger cars. The main reason is for fuel efficiency improvement however there is also a trend toward higher engine output for passenger cars. The control performance of Automatic transmission fluid is increasing, however, it also has characteristics which are not desirable for the lubrication of the gears. Tooth surface failures of carburised gears such as pitting fatigue have begun to increase for this reason. In this study, pitting fatigue tests were conducted using carburised gears with two methods of tooth surface strengthening. These were shot peening and manganese phosphate film treatment after shot peening. Three kinds of automatic transmission fluids were used Development of pitting of gears as influenced by differences in lubricating oil and the relation to gear wear was investigated by the experiments.
