[DML] backup lights on in Park--still no luck

[Peter Lucas <lucas@xxxx>]

I am still trying to diagnose the problem I have been having in which my
backup lights are on in Park and Neutral, as well as reverse.

I have removed the multifunctin switch from the transmission for
examination. The lights go on and off when I press one of the two little
buttons, but no positioning of the switch in its place will make the lights
go off with the car in Park.

Is there some kind of adjustment of the mechinism inside the transmission
that activates this switch, or is the switch itself defective? (it shows
some subtle signs of having been hit at some point). Does anybody have a
switch assembly left over from a governor computer transplant that they
would be willing to part with? Other than replacing the switch, I am
running out of debugging ideas.
