Methods and systems are provided for lubrication of a transmission. In one example, the transmission system may include a pair of shielded bearings attached to a first transmission shaft, each of the shielded bearings including at least one shield that forms a restriction between the shield and a race of the bearing and a cavity positioned axially between the pair of shielded bearings, wherein the restrictions tune lubricant pressurization in the cavity. The transmission system further includes a radial passage in the first transmission shaft in fluidic communication with the cavity and a lubricated transmission component.

A transmission assembly for a powertrain of a vehicle, includes, a control device and a transmission housing for housing a transmission, the control device mountable to the transmission housing and including a transmission mounting surface adapted to face the transmission housing, the transmission housing including a control device mounting surface adapted to face the control device, one of the transmission mounting surface and the control device mounting surface including a groove including at least a first and a second step deeper than the first step, and the other of the transmission mounting surface and the control device mounting surface including an outwardly extending guiding member configured to be received in the groove, 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 vice versa.
