I teach transmission rebuilding at my college for the last 18 yrs using a G-Tec brand trans tester, there is a you tube showing the set up and operation. Mine uses a 30HP 480 3 phase motor and has absorption unit built it to stop the back feed to the electric panel when you shut it down. The load cells use aircraft type brakes controlled with a air regulator. The driveshaft output clamps into the load cells with large 3 jaw heads with aluminum jaws.

There is a link to the video on their website for you guys to get your ideas.
