Abstract (en)
[origin: WO2008132013A1] The invention relates to a method for operating a transmission, especially an automatic transmission, comprising a dry starting clutch. Said starting clutch is especially configured as a friction clutch and a characteristic value is determined during operation in defined operating points, said value being indicative of the state of wear of the starting clutch. The method according to the invention is characterized by comparing a newly determined characteristic value with a characteristic value previously determined in a previous operating point. If the newly determined characteristic value deviates from the previously determined characteristic value to such an extent that it suggests a reduced wear of the starting clutch, it is assumed that the starting clutch has been replaced and a wear indicator of the starting clutch is reset in a defined manner.
