1990 Buick Riviera ProblemsInspect 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.
The spark plugs should be replaced every 30,000 miles and the spark plug boots should be checked for hot spots and cracks.
