Overdrive is the normally allowed position

It won't shift into overdrive until the speed is higher anyway ( such as the

highway / freeway )

If you are towing something or if you are driving in hilly country where the

transmission is constantly shifting between overdrive and drive , then you want

to shut the overdrive off using the switch on the end of your gear selector

lever ( P R N etcetera , O/D OFF will appear in your gauge cluster / dash )
