Auto Inhibitor Switch

[TwistedEL]

Hi all

I'm have the Falcon for sale and I want to have it all Mickey Mouse before it goes

It won't start in Park unless you move the selector between Park and Reverse

It'll start in Neutral. If I put the instrument cluster into diagnostic mode it shows the correct gear selection. I assume it's the inhibitor switch... I pulled the cover off the selector but it's not there - where is it and how hard is it to change out? How much should I expect to pay 2nd hand? It's a cop car and clicks from 3rd to 2nd without pressing the button - hopefully that's unrelated to the switch?

Cheers
