Beschreibung
Zusammenfassung:	A method for determining transmission and/or clutch parameters of a motor vehicle automatic transmission having at least one clutch, in particular for basic calibration of the transmission, in particular an automated manual transmission and/or a dual-clutch transmission, includes determining drag torque and/or kiss point of the clutch using an actuable synchronization device. The clutch has at least one drive side connected to an internal combustion engine output shaft and at least one output side connected to a transmission input shaft. The transmission output and/or drive shaft is blocked. The drive side of the clutch is driven. Basic calibration of the transmission is improved by driving the drive side of the clutch by an electric motor, providing a freewheel-shifted gear stage, and driving the drive side of the clutch by the electric motor in a rotation direction opposite the internal combustion engine output shaft.
