Pontiac Bonneville car starts but does not drive or reverse on Pontiac Bonneville

Some Pontiac Bonneville owners report experiencing issues where the vehicle starts but does not move in drive or reverse, which may indicate underlying transmission problems. These owners suggest that a professional mechanic should inspect the transmission to diagnose and repair any potential issues. Additionally, some owners have encountered difficulties related to the shift lock control ECU or solenoid, which can hinder the ability to shift into gear properly. In cases where the vehicle moves in reverse but not in drive, a slipping clutch may be the culprit, resulting in little or no power being transferred to the wheels. More severe cases may point to major internal transmission failure, especially if debris is found in the transmission pan during inspection. It is recommended that owners consult a qualified mechanic for a thorough diagnosis and necessary repairs to resolve these issues.
