The gear shift on my mom's '98 Oldsmobile Silhouette won't engage. It's "loose." To give a little more detail -- she has a little trouble getting the key out AND the back ventilation windows won't open -- in case that helps any to diagnose the problem -- or, could be an unrelated issue. If a solution is to check the transmission fluid, can you tell me where that is located?

On the 98 Silhouette, the PCM should be located in the air filter housing.

Under the bottom of the radiator on the there is a drain ****, you will have to raise the car and crawl under it to see it, be careful to not break it, the screw in plug is fragile, it will be hard to unscrew.

The first thing i would check is all 4 abs sensors at the wheels.You can do this with a volt meter set on ac voltage and spin the wheel if it generates voltage at all on the meter its good.

you'll need to remove your door panel (screws are by the door handle, arm rest, under door and side of door) and remove the cover adjacent to your mirror to remove the bolts to remove the mirror.

The problem is likely a faulty (sticking) relay - remove/replace the relay and check the lights extinguish.
