What does the M symbol on the gear shift of an automatic 09 chevrolet silverado for?
Never saw an M before. Did you look in your owners manual?
try the owners manual .
The "M' stands for Manual. By shifting the gear selector to "M", the number 1 will appear. By pressing the up button on the shifter itself, It will display numbers up to 6. It's purpose is that it "locks-out" all gears above it. So for example if you wanted to tow something like a trailer and you didn't want the transmission to shift higher than third gear, you would select "M" and press the "up" button until a 3 appears.
You can also have it hold gears longer and tell it when to up shift or down shift when you want within reason. Also if you select 2 for second gear it will start off in 2nd which over time can cause your transmission to wear out.
What is the best gear to ride on a daily basis in the city?
