Buick Riviera Problem Report
Buick Riviera Erratic Shifting of the Automatic Transmission
The transmission pressure control solenoid may fail causing erratic shifting. Our technicians tell us that partial dis-assembly of the transmission is necessary to replace a failed pressure control solenoid.
Sometimes it shifts like it has a shift kit in it and other times its super smooth. - Visitor
The control head is inop but has power to the head unit. Have replaced two times neither units...
I have had several lights in the A/C control panel fail. Any way to replace them?
The ABS master cylinder assembly may fail internally causing the ABS light to illuminate.
