Abstract

A large gearshift shock that occurs if a renewed gearshift operation is forcibly carried out in order to meet a new gearshift request made through a driver's operating an accelerator pedal or a signal from an operation lever during a current gearshift operation. Gearshift response lag occurs due to an attempt to avoid the large gearshift shock. To solve these problems, a control system for a gear type transmission is mounted. The control system is provided with a renewed gearshift disabling period, during which any renewed gearshift request to a third predetermined gearshift position made during a gearshift operation from a first predetermined gearshift position to a second predetermined gearshift position is disabled.
