Method of controlling transmission for reducing clutch abrasion and automatic transmission controlled by method

An automatic transmission 100 applied to a hybrid vehicle and configured to comprise an independent flow control valve 102 and an engine clutch cooling channel 103 for a cooling of an engine clutch 101, the automatic transmission 100 comprising:

• a detector 110 configured to detect whether a hybrid starter generator (HSG) operates normally and to transmit the detected data to a controller 120;
• the controller 120 configured to crank an engine using a driving motor 104 based on the detected data from the detector 110 and to simultaneously control the independent flow control valve 102 to supply an additional flow to the engine clutch cooling channel 103 by driving the independent flow control valve 102;
• and
• memory 130 configured to store the detected data from the detector 110 and to store a given program code for controlling an overall operation of the automatic transmission controlled by a transmission control method and data input and output when an operation based on the program code is performed.
