Cars that gan be towed

I do have a 1962 Chevy II (9 one made) and it has a 2 speed Power Glide transmission that has a second pump in the rear. I just today saw a mid 60s Chevy Impala that was being towed on all fours. I believe the 62 Chevy Power Glide was close to the last rear pump Transmission made. You can also push start my Chevy. I have to have a Automatic for my wife. She never learned how to use a Standard transmission.
