Q: Is it safe to drive with overdrive on or overdrive off?

Is it safe to drive with overdrive on or overdrive off?

My car has 196000 miles.
My car has an automatic transmission.

A: Hi, thanks for your question. This is usual...

Hi, thanks for your question. This is usually dependent on your driving conditions and habits. Overdrive is an extra higher gear in your transmission designed to increase fuel economy and drivability in freeway or long steady drive conditions. This does not mean you cannot drive with overdrive on when in town or city driving as your car will automatically downshift when appropriate for this kind of driving as well. The only time it may be advisable to drive with overdrive OFF is when you are towing something. The reason for this is to prevent the transmission from upshifting and downshifting repeatedly as the load on the car's engine and transmission are much more likely to shift more often when towing a load. Hope this helps and best of luck!
