- A release device for releasing a motor vehicle transmission from a shifter actuating shaft that operates the motor vehicle transmission_, the release device comprising: - a connecting element adapted for releasably connecting a motor vehicle transmission with the shifter actuating shaft; - biasing means acting on the connecting element into a position so as to arrange the connecting element and the shifter actuating shaft for operating the motor vehicle transmission; - a locking member associated with the connecting element and adapted to restrict the relative movement between the shifter actuating shaft and the connecting element, and - stop means comprising at least one protruding portion cooperating with the locking member such that when the stop means are driven to move along a first direction, the stop means abut the locking member causing the locking member to move together with the connecting element along said first direction operating the motor vehicle transmission, and when the stop means are driven to move along a second, opposite direction, the stop means do not abut the locking member allowing the locking member acting on the biasing means with the biasing means moving together with the connecting element and the locking member, operating the motor vehicle transmission, wherein the protruding portion of the stop means is arranged to cooperate with the locking member such that, when the locking member is in a first position, the protruding portion abuts the locking member causing the stop means to be locked against the locking member only in said first direction, and when the locking member is in a second position, the protruding portion does not abut the locking member allowing the connecting element to be moved relative to the stop means in both in said first direction and said second, opposite direction, and wherein the shifter actuating shaft comprises a worm screw attached to the stop means such that as the worm screw is rotated the stop means are caused to be displaced. - a connecting element adapted for releasably connecting a motor vehicle transmission with the shifter actuating shaft; - biasing means acting on the connecting element into a position so as to arrange the connecting element and the shifter actuating shaft for operating the motor vehicle transmission; - a locking member associated with the connecting element and adapted to restrict the relative movement between the shifter actuating shaft and the connecting element, and - stop means comprising at least one protruding portion cooperating with the locking member such that when the stop means are driven to move along a first direction, the stop means abut the locking member causing the locking member to move together with the connecting element along said first direction operating the motor vehicle transmission, and when the stop means are driven to move along a second, opposite direction, the stop means do not abut the locking member allowing the locking member acting on the biasing means with the biasing means moving together with the connecting element and the locking member, operating the motor vehicle transmission, wherein the protruding portion of the stop means is arranged to cooperate with the locking member such that, when the locking member is in a first position, the protruding portion abuts the locking member causing the stop means to be locked against the locking member only in said first direction, and when the locking member is in a second position, the protruding portion does not abut the locking member allowing the connecting element to be moved relative to the stop means in both in said first direction and said second, opposite direction, and wherein the shifter actuating shaft comprises a worm screw attached to the stop means such that as the worm screw is rotated the stop means are caused to be displaced.
