Maybe back in the 50s. Sliding gear transmissions have not been used since. In modern transmissions, the gears stay stationary and collars slide on the output shaft:

1936, I was looking for an example od a non-sycromesh transmission, like the reverse gear in your picture. Are then splines that the reverse gear slide on integral with the outout shaft?

Meshing all gears all of the time seems inefficient. Perhaps they aren't loaded so the friction is greatly reduced?

These videos remind me of how a differential works.

That's correct--there isn't a whole lot of friction because the gears are all spinning on roller bearings. Some power is lost just keeping everything moving, of course, but it's not as much as you might think from seeing that everything is always meshed.

Yeah, its easier to move spinning gears and to get them to mesh with others vs having them at a standing still. Thats assuming you are using gears in the first place.
