If the trans is operating correctly there is little to no wear on the friction pieces while engaged in gear. This is also true when at a stop.

Exactly. The only thing I do a little different with an AT is this. My driveway is on a slight incline pointing toward the house. I back into the driveway. When I pull out of the driveway, I coast a few feet in neutral and then put it in drive with my foot off the brake. I'm probably rolling about 2 mph, it's a bit less shock on the drive train. If I'm on level ground in park, I move the shifter to neutral, foot on the brake, and then to drive with my foot off the brake. Less shock on the drive train again. I've been doing that for as long as I can remember. FTR I'm not giving it any gas, when I shift from neutral to drive, I just don't have my foot on the brake.
Thanks you Demarpaint for a thoughtful reply. That's basically what I've been doing and why I asked about it. Sometimes I really wonder about the thoughtless responses often seen around Bitog and other car blogs. I would think the vast majority of car owners would say that anything but shifting with the car fully stopped, AND the brakes on, will do damage/produce more wear on the transmission. Again, it's why I asked.
No problem! We're here to ask questions and learn. I'm very easy on my equipment, in my younger days, not as much. I've thrown cars into reverse at speeds that would scare the [censored] out of any sane person, to see what would happen. I did this many decades ago. What I learned was they'd stall and roll forward. Popping them in neutral first and pegging the gas would cause a wheel to spin in the opposite direction and eventually the car will back up. Don't try this at home.
Now I drive easily. I know people who go from drive to reverse, and reverse to drive w/o stopping at slow speeds, common sense tells me it is not good. For the longest possible transmission life, I'd say drive it easy, come to a complete stop before changing directions, [I like to pause in N for a second or two before changing directions] and service the unit. Those are two good places to start. Living in an area where there's little to no traffic, and commutes involve nice traffic free highway conditions would be great too. Unfortunately we aren't all that lucky!
