1. A gearbox for a motor vehicle drivetrain comprising:
a gearbox housing; and
a differential inside of the gearbox housing configured for driving a first output shaft and a second output shaft about a center axis and for allowing the first output shaft and the second output shaft to rotate about the center axis at different speeds, the differential comprising:
a first side gear on a first side of the differential configured for being drivingly connected to the first output shaft;
a second side gear on a second side of the differential configured for being drivingly connected to the second output shaft;
a differential housing radially surrounding the first and second side gears; and
a first bearing rotatably supporting the differential housing with respect to the gearbox housing, the differential housing including axially extending holes passing therethrough in an axial direction, as defined by the center axis, from an exterior of the differential housing to an interior of the differential housing for directing fluid that is between the differential housing and the gearbox housing into the interior of the differential housing.
