Like HRTKD said, the Auto just does some of this for you. You are setting and releasing the the exhaust brake by tapping the brake or taping the gas. Go 55mph down hill, tap the brake and it will spool up the turbo and you'll feel it holding you back at 55mph. If you want to speed up to 60mph you tap the gas and cruise up to 60mph and tap the brake again and you'll feel it spool up again and hold you at 60mph. Its just like cruise control, but in reverse.
Will it downshift the transmission to maintain speed/boost like it will using cruise control?

So living in Florida and still yet to tow after 10 months, I have yet to use the engine brake. Next weekend I will be in the mountains in NC (mountains for me, hills for you guys out west.) Anyways I was looking forward to coming down the mountains and using the engine brake. But I believe rain is in the forecast. Isn’t it dangerous to use the engine brake on rainy roads?
( there’s a section of I-4 between Orlando and Winter Park where often tractor trailers lose it on rainy days— I heard that was a reason.)

I don't think the EB will do anything to the tranny by itself, but when used in conjunction with Tow/Haul mode it works best because TH mode will downshift for you, thereby increasing revs and increasing the pressure on the turbo vanes...which increases the EB's efficacy.
Don't trust a stranger on the internet with your safety, but I don't think the EB is strong enough to brake the wheels free, even in the rain. I feel much safer on steep hills with the EB on, even in the rain.
