What do the plus and minus symbols on an automatic transmission car mean?
1 Answers
The plus symbol represents upshifting, while the minus symbol represents downshifting. Principles of car gears: 1. N stands for neutral. Selecting the N button disengages the transmission and disconnects the driven wheel of the transmission. At this point, the car will move based on its own weight, momentum, and inertia, which is equivalent to turning off the engine. The car cannot rely on the engine to operate and move, so remember not to use neutral when going uphill. 3. D stands for drive. Its principle is to engage all possible forward movement gear ratios through the transmission, with these ratios generally ranging between 3-9. 4. Overdrive (OD). The principle of overdrive is to allow the automatic transmission to overload. If the automatic transmission is turned off, the gears will automatically downshift under hard acceleration.
