That was before my time. As I understand it, even then you had to get the vehicle moving quite fast.
Yes.
The rear pump was driven by the output shaft so you had to get the car moving fast enough to build pressure.
“Push start” for the early automatics meant pushed by another car.
“As I understand it, even then you had to get the vehicle moving quite fast.”
Not really. I’ve done it multiple times with cars doing maybe 3 mph.
