mostly you just ignore it and it does it's thing.
It will not allow you to over-rev, it will upshift regardless of what you tell it to do.
With the exhaust brake switched on it will seek to second when it can, and it will bring the rpms higher than it does under power, this is normal and not a worry.
The exhaust brake works pretty well, but not like the jake in your truck.
They lock up the torque converter at the top of first, just prior to shifting to second gear. Kinda feels like a "double shift" or like something is slipping. Threw me at first, but have been assured it is normal.
I never shift manually, just put it in drive, and use the exhaust brake switch as needed.
