1. A method for controlling a transmission, the method comprising:
determining, by a controller, whether the controller receives an acceleration pedal off signal corresponding to a lift foot up (LFU) shift request signal from an acceleration pedal sensor;
determining, by the controller, whether an output signal value of a brake pedal sensor detecting a position value of a brake pedal is less than a brake reference value when the acceleration pedal off signal is received;
determining, by the controller, whether a gear shifting progressing rate of the transmission performing a LFU shift in response to the LFU shift request signal is less than a progressing rate reference value when the output signal value of the brake pedal sensor is equal to or greater than the brake reference value; and
controlling, by the controller, the transmission to hold the LFU shift when the gear shifting progressing rate of the transmission is less than the progressing rate reference value.
