you cannot by any chance spin the transmissions main oil pump by the output side - no mattter even if you speed it to 100 km/h
The only transmissions can be started like that are those that have rear pumps, e.g the old MB 722.1xx. it can start by moving the car to 50 km/h then engaging D - it should be done with extreme care and in a very short time otherwise you may damage the clutches because the rear pump pressure is not as high as the front pump and does not move fluid quick.
