The present invention is directed to a shift actuator assembly for a vehicle transmission including a shift actuator (2) moveable between a number of predetermined shift positions, a sensor (24) for sensing the shift actuator position, a mechanical detent mechanism (30, 32, 34) such that at the predetermined shift positions a detent engagement feeling is generated, an adaptive braking mechanism (10, 12) acting on the actuator (2) to selectively increase the resistance against shift actuator movements, and a controller (20) receiving the input from the position sensor (24), wherein the controller (20) is arranged to control the adaptive brake mechanism (10, 12), characterized in that the controller is arranged to control the adaptive brake mechanism so that, if the shift actuator (2) reaches any of the predetermined shift positions, the braking force of the adaptive braking mechanism is increased such that the actuator movement is completely stopped for a predetermined period of time, whereafter the adaptive braking mechanism is released.
