Where is the automatic transmission gears console light bulb and how do you change it on a 1991 Pontiac Firebird?

The bulb is located to the rear(back near the #1) underneath the console plate. It is a smaller bulb like a #194. You do not have to remove the shift handle. Take out the ashtray, and carefully pry up along the edges of the plate. It is held in place by tabs that fit into the console. You'll be able to lift it high enough to see the wire to the bulb connected to the underneath of the gear indicator, twist the bulb housing and pull off, take old bulb out by pulling it straight out and replace. Assembling is the reverse of the above steps.
