It's simple for some automatic tramsmissions when you put your gear selector into the plus + and minus - selector you gain the ability to change gears when you so desire. The + denotes an nupshift that is changing to a higher gear, while the - means downshifting which means lowering a gear.
Then, what are the plus and minus on my shifter Chevy Malibu?
Like controlling a manual transmission, tapping the “plus” button puts your car in a higher gear, and tapping the “minus” button puts your car in a lower gear.
Also, what is the plus and minus sign on my gear shift Chevy Equinox?
Probably similar to paddle shifters, minus will downshift to lower gear and plus is up shift to higher gear. 16 people found this helpful. It is for shifting up and down manually.
What is the button on the gear shift for?
In that case, the button you are asking about is the overdrive-off switch. When you press it you should see an indicator illuminate on the dash saying something like "O/D Off". As you accelerate in an automatic, the transmission selects a drive gear based on how much you push the accelerator.
Is it bad to manually shift an automatic?
The simple answer is yes, but you need to acknowledge the fact that the opposite is not quite possible — you cannot go automatic with a manual transmission set up. It comes as an effective measure when you are going down a steep hilly area range.
