same thing like a manual. slow down with brake then just before you come to a stop, push in the clutch... like a regular manual.
Those are pretty nice but you see what it is doing, I drive truck ( tripples) and these rigs that have auto manuals, are getting a lot of inexperienced drivers on the road for a big rig like this..... I drive a super ten... ( like a 5 and a 2 speed), and I am still learning.
All I can tell you is drive and resect that rig like it can kill you because it can and will... If you are overconfident... be carefull
