In a method for correcting clutch data used for controlling the engaging/disengaging operation of a friction type clutch, meet position data is up-dated only when the clutch temperature is less than a prescribed value and the clutch data is corrected by the use of the up-dated meet position data, whereby learned meet position data affected by clutch temperature increase is prevented from being used for the correction of the clutch data. As a result clutch data, is properly corrected regardless of change in the clutch temperature.
