Taking the auto out of O/D on my pickup will allow it to downshift and provide engine braking while decelerating and I assume prolong brake life. I use this in town and when coming off the freeway. In O/D it will just coast and the brakes are the sole stopping power. So, a possible cause for more wear over a manual transmission.
I'm sure the logic is not the same on all transmissions and some are probably programmed to downshift based on speed/rpm regardless of gear selector position.
