How is it done in automatic transmission vehicles? full throttle or engine?

In the past, when we were going down the ramp, we would see if the gears were downshifting, and now I don't know how good or bad everywhere, but I do not know my father's traditions.

Nice share

You have to make it every 20k km

very informative, good health

Nice sharing thank you. It seems like the fastest and most satisfactory test that can be done when buying a second hand car. Especially in high compression cars.

I saw the beautiful sharing applied for the first time
