Kind of...except that transmission output shafts are subject to the torque from the engine, times the gear reduction in low gear. Which is why automotive transmissions have larger output shafts than input shafts.

Interesting tests, thanks for sharing! It's a nice transmission, but not nearly as cost effective as the AM shifters as noted. Unfortunately real life generally means economic considerations are top priority for a design.
