ABSTRACT:
Disclosed is a gear shift controller for an automatic transmission with a gear shift, having a hydraulic torque converter; a gear change group, having a plurality of gears, each gear providing a different transmission ratio for the transmission of power from said hydraulic converter to the output of the transmission, each of said gears having a gear train; a one-way clutch interposed in at least one of said gear trains; a plurality of clutch means operatively connected with said gear trains for actuating each of said gear trains selectively; a gear change determination circuit operatively connected with said clutch means for controlling the operation of each of said clutch means according to a predetermined gear-shifting program; a coasting detection circuit operatively connected with said gear change determination circuit, for detecting a car in the coasting state; a gear shift limiting circuit, operatively connected with said gear change determination circuit, for actuating only said gear train in which said one-way clutch is interposed immediately regardless of the operation of said gear change determination circuit, when said coasting detection circuit has determined the car to be coasting; and an operation transfer control system for transferring the operation of the gear shift limiting circuit.
