1997 Cadillac Seville V8 Front Wheel Drive Automatic

The scrolling message on the dash reads, "Theft System Problem" followed by "Car May Not Restart" The car does start however when the gear shift is moved from park down through nuetral and into drive positions the transmission does not engage. The trans does not engage in any of the positions -the engine idle fluctuates as you go from one position to the next. The trans will go into nuetral and was opperating normally prior to this -with no grinding, clunking or whirling sounds. Nor is it leaking or requiring added fluids frequently. What is wrong and how can I repair the problem.

The theft system fault may be a result of a failing ignition lock cylinder, there are small wires that eventually break at the cylinder. If the transmission does not move in any gear, forward or reverse, you may need to have some diagnosis performed. A line pressure test would be recommended for starters.
