2004 Pontiac Bonneville Problems

Transmission Pressure Control Solenoid Failure May Cause Erratic Shifting

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.

Engine Stalling Due to Mass Air Flow/Crankshaft Position Sensor Failure

The mass air flow or crankshaft position sensor may fail causing the engine to stall intermittently. Proper diagnoses will be necessary to determine the cause of any stalling condition.

Water Pump May Fail Prematurely

The water pump may develop a coolant leak resulting in an engine overheating condition.
