<p>The present invention intends to provide a shift control apparatus for transmission which can reduce or prevent the speed-change shock and/or noise at the balk point where the sleeve engages with the ring in the shift push-in process. In order to achieve the above object, a shift control apparatus for a transmission comprises a plural sets of paired free-rotate gears, a plural sleeves 17, 18, a plural sets of paired synchronize rings 27 to 29, an actuator 65, 70 for actuating the sleeve, a control means 50 for controlling the actuator based on a speed-change command. The control means 50 controls the actuator 70 so that the sleeve 18 is driven by a first drive force Qmax upon starting of a speed-change operation, and is driven by a second drive force Q2 smaller than the first drive force at least during a first time period T3 'to T4 'from a time before a balk point B of the sleeve where the sleeve engages with the synchronize ring in a shift push-in operation. <IMAGE></p> |
