How does your transmission work? And how to know it's in trouble.

So, how does this important part of your car accomplish these important tasks? And how will you know when it’s failing to work properly?

Roles your transmission plays

1.Shifts into gear automatically

When healthy and working properly, your car’s transmission should shift gears automatically, giving you the pace and performance you need on the road. A sure sign your transmission is in trouble: your car refuses to shift gears. Low transmission fluid or the wrong viscosity (thickness) of fluid can prohibit your transmission from being able to function properly, or, your transmission might simply require an adjustment in the shift cables or clutch linkage.

2.Changes gears smoothly

Your transmission should change gears so smoothly that oftentimes, you won’t even be able to notice. If you notice a grinding or shaking in your car when you are changing gears, the source is most likely a worn clutch or transmission gear synchronizers that are also worn or damaged.

3.Stays in gear automatically

Your transmission will help your car remain in gear automatically. However, if your transmission is experiencing trouble, your car might unexpectedly slip or pop out of gear. Oftentimes, this is a result of a problem within your car’s computer system.
