ABSTRACT:
The rotational speed of an engine Ne and a drum rotational speed Nt of a clutch Cl are compared against each other to determine a power on/off. For a 2.fwdarw.3 and a 2.fwdarw.4 shift in the power off condition, a timing solenoid SL5 is turned on (duty cycle of 100%) to accelerate the termination of a preceding speed range, thus increasing a time delay between such termination and the activation of a new speed range to be established. For other shifts, a time difference between the termination of a preceding speed range and the activation of a new speed range to be established is adjusted, by energizing the solenoid SL5 in accordance with the throttle opening .theta. and the vehicle speed No such that SL5 is energized with a high duty cycle for a longer .theta. and with a low duty cycle for a smaller .theta..
