An automatic transmission fluid leak may develop from the rubber section of a transmission cooler line. In some cases the rubber section of hose can be replaced. In others, the complete cooler line must be replaced to correct this type of leak.

1999 Buick Riviera Problems
Brake fluid can become dirty and may cause problems in the brake system; it should be flushed every 60,000 miles.
The intake manifold gasket may develop external engine oil leak. The manifold gasket will need to be replaced to correct this issue.
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 mass air flow or crankshaft position sensor may fail causing the engine to intermittently stall. It may be necessary for the engine to cool down before it will restart.

1999 Buick Riviera Reviews
Have owned 2 99s and 1 98 which are effectively the same car. Obviously I love my Rivieras That said, they all have had supercharger coupler failures, leveling system failures, and trunk leaks, all of which are relatively easy to repair with the leveling system the most expensive to repair. One had a bad intake manifold gasket that leaked antifreeze into the intake that I never repaired. Have problems with the transmission shifting that was fixed by replacing the fluid & filter and then driving it for a couple months. Replaced 1 radiator, 1 oil pressure sending unit for Misc other problems & issues but have been driving these cars for almost 15 years. My current Riviera is a Silver Arrow.
Love this car, but there are a bunch of little problems.
