Thats how you drive in the mountains so as not to wear out your brakes by riding them all the way down when you need to slow down. Trying to hold the speed limit using your brakes going down a mountain is extremely stressful and can lead to over heating which IS NOT WHAT YOU WANT COMING DOWN A MTN! LOL!

What you are doing is simply mountain driving. Is it good for the transmision? Well, I don't know. It's pretty good on your brakes though, lol

Is it a strait automatic, or a manuamatic? I'm pretty sure it's a straight auto, if so, you're causing undue strain on it, yes. If you wanna shift your own gears, drive a manual. Otherwise, let the transmission do it. The only time the manual shift functions should be used on regular automatics are when towing, pretty much.

No, you're not.

All you are doing is applying an additional clutch which causes a one-way clutch to lock up and lock the engine to the input shaft. It's no harder on the transmission than driving down the road.
