47-59 B/W R10 Overdrive Operation Question

[mr48chev]

All I am going to say is that on my 51 Mercury coupe with BW overdrive in the 1960's it fully freewheeled when slowing down in overdrive.

The reason being is that I had what others said were the loudest pipes in town but when I didn't want cops to hear that rapppppp when slowing down in town I would leave it in overdrive and the engine would go to an idle and I would have to use the brake rather than the engine to slow down to a stop. That trick saved me many a ticket.

The overdrive gave the best of both worlds though. Fair acceleration with the lower geared rear end even with the flathead and decent gas mileage at 1963 highway speeds for a kid who could barely afford to put a couple of bucks worth of gas in at a time.
