What are the most likely Donor vehicles for the A 500 4 speed automatic?

Maybe someone mentioned it and I missed it BUT regarding the manual toggle switch for lockup and overdrive, do these stay engaged as you slow down below a certain speed? I'd think that as you get below say...45 mph, the OD would disengage.

I had toggles in the old White Whale Dodge pu. No, it would stay locked up and would kill the engine at a stop light if you forgot.
