A transmission, a powertrain, a vehicle and a method for operating the transmission

A transmission for a vehicle comprising:

• a first shiftable gear arrangement and a second shiftable gear arrangement, the first shiftable gear arrangement being shiftable between a first plurality of gears with different gear ratios and the second shiftable gear arrangement being shiftable between a second plurality of gears with different gear ratios, wherein the first shiftable gear arrangement is drivingly connected to a first input shaft and the second shiftable gear arrangement is drivingly connected to a second input shaft, wherein the first input shaft is configured to be drivingly connected to a first power unit and the second input shaft is configured to be drivingly connected to a second power unit, and
• a range gear arrangement drivingly connected to an output shaft, wherein the range gear arrangement is shiftable between at least a low range gear state and a high range gear state, wherein a gear ratio of the range gear arrangement in the low range gear state is greater than a gear ratio of the range gear arrangement in the high range gear state, wherein the first shiftable gear arrangement is configured to selectively transmit torque from the first input shaft to the range gear arrangement using one of the gears of the first plurality of gears and the second shiftable gear arrangement is configured to selectively transmit torque from the second input shaft to the range gear arrangement using one of the gears of the second plurality of gears, such that the range gear arrangement together with the first and/or second shiftable gear arrangement provides a set of low range gears and a set of high range gears between one or both of the input shafts and the output shaft,
• wherein the transmission is further shiftable to a by-pass gear state, in which the second shiftable gear arrangement is shifted to a by-pass gear, the by-pass gear being comprised in the second plurality of gears, such that power is transferrable from the second input shaft to the output shaft without passing through the range gear arrangement.
