Nevermind - I figured it out. In case anyone needs to do this, here is
how it's done:

1) Remove the plastic piece surrounding the metal piece that contains
the PRND holes by prying it up with your fingers where it meets the
ashtray.

2) Remove the metal piece by pushing in the 4 tabs (2 on right side, 2
on left side). Note that it looks like there are 8 tabs, but it's
actually only 4.

3) Remove the circuit board. It unplugs on the drivers side.

Then, I looked down the slot where the rubber flows (much like a
rolltop desk) and saw a penny in there, which I removed with a
screwdriver.
