Frank,

Pretty convincing instructions, to me.
So it is ok to downshift with an automatic.

An old retired MB mechanic used to tell me otherwise.
He said it was cheaper to replace the brakes vs replace a tranny.
BTW this is in an area where steep hills are abundant, and brakes are used heavily, daily.

EDIT: I had used DOT 4.
