PURPOSE:To reduce a speed change shock by slowing down the execution of the gear change for a specific time in a shift-up from a speed change range a one-way clutch is engaged, and extending the slowing-down time when the throttle is fully closed more than in the other cases. CONSTITUTION:When a shift-up from a speed change range in which a one-way clutch is engaged is discriminated by a gear change discriminating device 31C, the oil pressure control device 30 of a speed change mechanism 22 withholds the speed change to the upper range for the time T1 set by the first timer producing device 31D. And after the set time T1 passes, the first timer/the second timer selecting device 31F operates the electromagnetic valves S1 and S2 of an oil pressure control circuit 24 instantly to shift the speed to the upper range in case other than the case the throttle is fully closed, responding to the signal of a throttle discriminating device 31B. On the other hand, when the throttle is fully closed, the speed is shifted to the upper range after the time T2 set by the second timer producing device 31E. In such a way, the generation of a speed change shock can be reduced. |
