Eric,
That's correct, if the car is moving, the pump is pumping. The switch moves
a valve which send fluid to the operating pistons which engage the cone
clutch, yada yada...

seconds for the pressure to build and the overdrive to engage. I think I've
counted as much as 15 seconds with cold fluid. Its normally more like three
seconds. <<quote

system as soon as the car rolls. Switching the OD on releases the pressure
to some (for me) mysterious ways, so that the OD engages. I'm sure a more
knowledgable expert can explain it technically correct.
