Full gas: load on the drive train in different gears

Hello, I wonder how different the components of the drive train are loaded in different gears. Let’s take the following two examples to compare: – Driving in 1st gear, starting from 2000 rpm to 6500 rpm Full-speed – Driving in 4th gear, starting from 2000 rpm to 6500 rpm Full-speed According to my logic, the engine would have to be less loaded in 1st gear, because it has to fight with less resistance and turns up faster, so it will only be loaded for a shorter time. But what about the remaining drive train (two-mass swing wheel, clutch, gear, cardan shaft, hardy disk, differential, drive shafts)? I imagine that in 1st gear more torque will arrive at the wheels than in 4th gear. Because it is also easier to let the wheels spin through in 1st gear than in 4th gear. That would mean that the remaining drive train will be loaded more in 1st gear than in 4th gear. Is this right?
