Abstract
Under a condition where a manual mode is selected by a selecting lever, when a down-shift switch is turned ON and down-shift is requested, an engine speed N,after the down shift is calculated (step S,), and if this engine speed exceeds the overspeed N,, the down-shift is made to stand by, and a down-shift elapsed time T,is incremented. When the incremented elapsed time is within a down-shift effective time T,(predetermined time) which is set on the basis of a gear position, throttle opening degree, vehicle speed, deceleration, etc., a down-shift command is sent (step S,) when the engine speed N,reaches the overspeed N,or lower, whereas when the down-shift elapsed time T,reaches the down-shift effective time T,or longer, the down-shift stand-by condition is released (step S,).
