OD Overdrive Button Swap Possible?

[eplanajr]

I recently replaced my broken shifter with a new-to-me shifter, works like it's supposed to except...

The OD button doesn't stay down when I press it. I can hold the button down to turn off OD, but the moment I release the button, its back to normal OD driving. Can this switch be replaced?

Another dumb thing, is that I threw away my old "broken" shifter, so I can't just swap in my old one, so I have to try to find the button or a whole other assembly...

You got a shifter out of a later model 4runner. They use a momentary button just to signal the ecu that you want the od off. If you hit the button again, this tells the ecu that want od on.

This will reset when the 4runner is turned off. So the overdrive is back to normal when it starts back up.

The older 4runner when the od is off, it stays off until the the button is pushed back on.
