Your speedo will read the same as its driven off the rear of the tranny. For a given speed with the same gear ratio in the rear you will see a little higher rpm on the automatic because of the slip. So a little more engine noise for the same speed perhaps. I estimate the slip might be about 200 rpm for a given speed.
