1. An actuator for the actuation of at least one movable member of a motor vehicle transmission, said actuator comprising:
a housing and a cover defining an internal volume in which are received at least one electric motor having a stator and a rotor mounted on an end of a rotor shaft extending along an axis X1,
a motor pinion fixed to an opposite end of the rotor shaft to the rotor,
a reduction mechanism driven by the motor pinion, and
a pin mounted so as to be able to rotate at the end of a shaft extending along an axis X3 and able to be engaged in the movable member of the transmission,
wherein the shaft of the pin is rotationally guided by a rolling bearing and a slide bearing,
wherein a seal is disposed axially between the rolling bearing and the slide bearing along the axis X3, and
wherein the cover comprises a through-hole having three bores with different diameters, the rolling bearing, the seal and the slide bearing each being disposed in one of the three bores, the rolling bearing is located on an outer side of the cover and the slide bearing is located on an inner side of the cover.
