Claim 12:
13. The powertrain according to claim 12, further comprising a second powertrain module, wherein the second powertrain module comprises a second power unit, and a second transmission comprising:
an input shaft drivingly connectable or connected to a power unit during use;
a planetary gearset comprising a sun gearwheel, one or more planet gearwheels, a planet gearwheel holder and a planet ring gearwheel;
a first gearwheel, a second gearwheel, a third gearwheel, a fourth gearwheel and a fifth gearwheel;
an output shaft;
wherein the first gearwheel is in driving connection with the second gearwheel, each one of the third and fourth gearwheels is in driving connection with the fifth gearwheel and wherein one of the third, fourth or fifth gearwheels is rotatably connectable or connected to the output shaft, and
wherein the transmission further comprises at least two gear engaging devices which are configured to provide at least four selectable gear connections, comprising:
a first selectable gear connection in which the planetary gearset is internally locked;
a second selectable gear connection in which the planet gearwheel holder is rotatably connected to the third gearwheel;
a third selectable gear connection in which the planet ring gearwheel is drivingly connected to the fourth gearwheel; and
a fourth selectable gear connection in which the planet ring gearwheel is rotatably locked to a fixed member;
wherein the planet ring gearwheel is rotatably connected or connectable to the first gearwheel and wherein a first gear engaging device of the at least two gear engaging devices is configured to be provided in a first gear engaging device first state where it rotationally connects the second gearwheel to the fourth gearwheel and in a first gear engaging device second state where it rotationally disconnects the second gearwheel from the fourth gearwheel, wherein the third selectable gear connection is provided by at least setting the first gear engaging device in the first gear engaging device first state, wherein the second power unit is drivingly connectable or connected to the input shaft of the second transmission.
