<p>PURPOSE: A transmission control method of an AMT hybrid vehicle is provided to perform a smooth transmission and a stable synchronization operation in spite of a rapid change of the car speed in the AMT hybrid vehicle, thereby preventing the failure of a gear engagement, preventing the driveability by minimizing a power blockage status, and improving the durability of the transmission. CONSTITUTION: A transmission control method of an AMT hybrid vehicle is comprised of an activeness maintenance of synchronization step(S40) suppressing a collapse of the synchronization by generating a torque to a motor in consideration of the inertia of the motor connected to an input shaft in the transmission and the change of a control target rotation speed of the input shaft. The activeness maintenance of synchronization step is performed if a synchro load torque, which is obtained by multiplying the amount of change of the control target rotation speed of the input shaft by the moment of inertia of the motor, is not 0 after starting a gear engagement to a target transmission terminal.
