My 1998 Olds has 175 K on it and recently the Traction control engages every time I start it and begin driving. I have to turn Traction Control off every time I start it now, before I engage the drivetrain and begin moving or it will engage. Also the Light for the Anti Lock brakes comes on half of the time right after Traction Control engages

I am not quite sure what you are trying to do. The anti theft is always engaged as there is chip in the key that must match in order for the vehicle to start. What do you want to accomplish?

The traction control system is controlled through the Anti-lock brake system. The way it works is if one of your wheels starts spinning the ABS applys the brake to that wheel to transfer power to the oppsite wheel that is getting traction. If your ABS is bad then your Traction control won't work. To check it I would find a parking lot on a wet day. In an open space mash in the gas. if you hear the ABS system kick in and you don't squall the tires then your good. My guess is you won't. What I would be worried about is will my ABS work. When checking the traction control is a good time to check the ABS. Acclerate to around 15 mph, then mash the brake as your live depended on it. If you hear a motor run and feel a vibration or grind in the brake peddal, then it works.

Anti-Lock and Trac Off lights are lit on my 1999 Alero, as well. They usually come on after about 5 minutes of driving, but are not always on when I start the car.

Normal thing that happens as long as onone (worked) on it, is the vacume hose going to the engage sevevo under the battery box has fell of on either end or is brocken on the way there. Then the once or now leaky battery acid ate up this same servo. then the cable going to the front axel breaks sticks falls off or even someone needing one climbed under your truck while parked somewhere to get one to replace their brokeen one now you don't have one then theaxel engage arm or gearset is damaged

sounds like you have a wheel speed sensor going out.. need to have it scanned to see which one is dropping out and making abs kick in..
