A gear shift system comprising: a gearbox having a shift shaft to which a shift actuation lever is connected, a shift lever remote from the gearbox, a transmission mechanism for transferring shift commands from the shift lever to the shift shaft including a cable or rod connected with one of its ends to the shift lever and with its other end to a linkage comprising at least two actuating members including an input actuating member (4; 34) which is moved in response to shift lever movements transmitted by the cable or rod, and the shift actuation lever, wherein between input actuating member (4; 34) and shift actuation lever there is a connection with limited play which allows a limited shift in the relative positioning of the input actuating member and the shift actuation lever, a servo mechanism connected to the shift shaft to assist in turning the shift shaft, a servo valve arrangement for controlling the servo mechanism responsive to the relative positioning between the position of the input actuating member (4; 34) and position of the shift actuation lever dictated by the input actuating member, a detent mechanism including a spring biased detent plunger and a detent track for providing a perceptible feedback of a shift operation to the shift lever, characterized in that the detent mechanism is acting between (i) the input actuating member (4; 34) or a component that is linked to the input actuating member such that it follows its movements, and (ii) the shift actuation lever or a component that is linked to the shift actuation lever such that it follows its turning movements, so that the detent plunger reaching a central valley of the detent track indicates that the shift shaft has reached its neutral or in-gear position as dictated by the input actuating member (4; 34). a gearbox having a shift shaft to which a shift actuation lever is connected, a shift lever remote from the gearbox, a transmission mechanism for transferring shift commands from the shift lever to the shift shaft including a cable or rod connected with one of its ends to the shift lever and with its other end to a linkage comprising at least two actuating members including an input actuating member (4; 34) which is moved in response to shift lever movements transmitted by the cable or rod, and the shift actuation lever, wherein between input actuating member (4; 34) and shift actuation lever there is a connection with limited play which allows a limited shift in the relative positioning of the input actuating member and the shift actuation lever, a servo mechanism connected to the shift shaft to assist in turning the shift shaft, a servo valve arrangement for controlling the servo mechanism responsive to the relative positioning between the position of the input actuating member (4; 34) and position of the shift actuation lever dictated by the input actuating member, a detent mechanism including a spring biased detent plunger and a detent track for providing a perceptible feedback of a shift operation to the shift lever, characterized in that the detent mechanism is acting between (i) the input actuating member (4; 34) or a component that is linked to the input actuating member such that it follows its movements, and (ii) the shift actuation lever or a component that is linked to the shift actuation lever such that it follows its turning movements, so that the detent plunger reaching a central valley of the detent track indicates that the shift shaft has reached its neutral or in-gear position as dictated by the input actuating member (4; 34).
