So if downshifting in an auto is a bad thing to do, then wouldn't that mean using the OD is a bad thing to do too, since essentially what you're doing is manually downshifting? If such is the case, wouldn't that render arguements of people saying downshifting is bad...useless?

I don't do it, I only shift up on occasion, but it is something that just struck me as a little odd.

 

Are you saying taking the car out of O/D when it already is in it? So if you are driving in O/D (4th) and take it out of that it will drop to 3rd? I don't know much about autos but I'd imagine the car is designed for this action. It may be similiar to when the car kicksdown a gear when accelerating rapidly or going up a hill. Does that make sense?

 

If you do it at the wrong speeds, yes. If you dont, then no.
