A method of diminishing shift shock in a stepped shift mode in a continuously variable transmission. A continuously variable transmission having an automatic shift mode and a stepped shift mode possesses a shift shock diminishing control function. In this control, when shift-down is made in the stepped shift mode (S.1), a timer is allowed to start counting (S.2) and the magnitude of deceleration G during change of the change gear ratio by a control motor is compared with a threshold value (S.4), and if the deceleration magnitude is larger than the threshold value, the supply of electric power to the control motor is stopped for only a very short time to decrease the deceleration G thereby diminishing the shift shock (S.5). |
