Over drive light wont go off when i push the button on the side of the gift shift my transmission shift good

Hello, if the overdrive "off" light will not go off, it means there is a problem. Diagnostic testing is needed to find out what is going on. You may think your transmission is "working fine" but that light staying on is a clue to a concern.

Even a malfunctioning button is possible, but it's more likely a noted electronic transmission operation concern.
