1. A transmission assembly for a powertrain of a vehicle, comprising,
a control device and a transmission housing for housing a transmission, wherein the control device is mountable to the transmission housing,
the control device comprising a transmission mounting surface adapted to face the transmission housing when mounted thereto,
the transmission housing comprising a corresponding control device mounting surface adapted to face the control device when the control device is mounted to the transmission housing, wherein,
one of the transmission mounting surface and the control device mounting surface comprises at least one groove, which groove comprises at least a first and a second step, as seen in a direction being perpendicular to the one of the transmission mounting surface and the control device mounting surface, wherein the second step is deeper than the first step, and
the other one of the transmission mounting surface and the control device mounting surface comprises at least one outwardly extending guiding member, which is configured to be received in the groove, and wherein the outwardly extending guiding member and the groove are configured so that the outwardly extending guiding member can slide in the first step until it reaches the second step, whereafter the transmission mounting surface can be moved towards the control device mounting surface or whereafter the control device mounting surface can be moved towards the transmission mounting surface,
wherein the control device comprises a set of actuators extending from a plane defined by the transmission mounting surface, wherein the control device is configured to actuate gear shifting members of the transmission assembly by moving the actuators in an actuation direction.
