I have a manual myself but I wouldn't do that. I heard those are supposed to help the tranny so it doesn't have to work as hard going uphills and such. Not sure.
Probably. There's no point really, let's say you are in 3rd gear going 40mph with 2-3k rpm, if you hit the revs fast enough, it will automatically shift down to 2 to grab those higher revs, then shift back up to 3rd. I really just let the auto do it, mind you, unless you are driving manual, the car is smarter than you LOL....Yup it does. But I was just asking if it was damaging to the engine to do so
