1991 Cadillac Seville Problems

Inspect transmission/fluid every 30,000 miles

You may be able to prevent transmission problems by servicing the transmission and inspecting the fluid every 30,000 miles. If the fluid is dark or burned then the transmission system should be completely flushed.

Replace spark plugs every 30,000 miles

The spark plugs should be replaced every 30,000 miles and the spark plug boots should be checked for hot spots and cracks.

The Parking Brake May Not Automatically Release

The parking brake may not release automatically due to a failed vacuum switch or actuator. Our technicians tell us that if vacuum is supplied to the actuator when the transmission is in gear, the vacuum switch is functioning and replacing the actuator should correct this concern.
