Overdrive button is beginning to fail/stick. Works sometimes, but not always. on 1993 Dodge Dakota

Where can I find a replacement button? Dodge Online has nothing.

Set it to OD and leave it, that why they call it an 'automatic'.
It changes on it's own. But thanks for the input.
You mean the button changes on it's own?
Spray it good with WD-40, may help keep it from sticking.
