Cadillac CTS 2014-2019 Drivetrain Specifications

The 2014-2019 Cadillac CTS features a drivetrain with a 2.0L turbocharged I4 engine producing 272 horsepower, a 3.6L V6 engine producing 335 horsepower, and a 3.6L twin-turbo V6 engine in the Vsport model producing 420 horsepower. Available transmissions include a 6-speed automatic or manual, with optional all-wheel drive (AWD). The drivetrain is designed for optimal performance, offering rear-wheel drive (RWD) as standard and AWD for enhanced traction. Fuel economy estimates range from 19-22 MPG city and 28-30 MPG highway, depending on the engine and drivetrain configuration.

Regular maintenance is crucial for the drivetrain's longevity. Oil changes should be performed every 5,000 to 7,500 miles using synthetic oil. Transmission fluid should be replaced every 30,000 miles, and coolant every 50,000 miles. Drivetrain components such as the differential and transfer case should be inspected every 15,000 miles. Additionally, AWD systems require periodic checks of the electronic controls and sensors to ensure proper operation.

To replace a drivetrain component, start by raising the vehicle and removing the necessary underbody panels. Disconnect the battery and any electrical connectors linked to the component. Use specialized tools to remove bolts and fasteners securely. Once the faulty part is removed, install the new component, ensuring proper alignment and torque specifications. Reconnect all components and test the system for leaks or malfunctions before driving.

Common drivetrain issues include vibrations, noises, or loss of power. Start by checking fluid levels and looking for leaks. Inspect drivetrain mounts and axles for wear. Use a diagnostic scanner to identify error codes related to the AWD system or transmission. If vibrations occur, check tire balance and alignment. For persistent issues, consult a certified mechanic to avoid further damage.

To optimize drivetrain performance, ensure regular maintenance, including fluid changes and inspections. Use high-quality synthetic fluids to improve efficiency. Avoid aggressive driving and extreme temperatures. For AWD models, maintain proper tire pressure and balance. Consider upgrading to performance-oriented tires for enhanced traction. Additionally, keep the vehicle's software updated to the latest version for optimal drivetrain operation.
