1993 Chevrolet Corsica Transmission status

After hitting a hole on the road the control arm separated from the front bolt weld. That caused the wheel to shift back and the trans-axle to split from the firs boot ( near the gear box). I was worried that transmission was affected so I removed the broken trans-axle, jack up both front wheels, started the engine and shifted trough the gears. I was expecting both transmission ends to spin but only the one with the missing trans-axle is turning while the other one with the wheel attached it stays still. In this case I am wondering if this is normal and is worth replacing the control arm and the trans-axle. I appreciate any suggestion on how to investigate the status of the transmission.
