Pontiac Pontiac G5 2007-2010 Drivetrain Specifications

The 2007-2010 Pontiac G5 is equipped with a front-wheel-drive (FWD) system, compatible with 2.2L L4 and 2.4L L4 engines. The drivetrain includes a 5-speed manual or 4-speed automatic transmission. It is important to ensure that replacement parts match the specific model year and engine type, as variations exist. Always consult the vehicle’s VIN or a trusted parts catalog for precise compatibility.

Regular maintenance for the Pontiac G5 drivetrain includes checking and replacing transmission fluid every 30,000 to 60,000 miles, inspecting CV joints and boots for wear, and ensuring the differential is lubricated. Additionally, monitor the driveshaft and axles for damage. Adhering to the manufacturer’s maintenance schedule, typically outlined in the owner’s manual, ensures optimal drivetrain performance and longevity.

To replace drivetrain components, first, safely lift and secure the vehicle. Remove the wheels and disconnect the axles from the transmission. Replace worn parts such as CV joints, axles, or the driveshaft, ensuring proper torque specifications are followed. Reassemble components, refill transmission fluid, and test the vehicle for proper operation. Always refer to the service manual for detailed instructions.

Common drivetrain issues include CV joint noise, transmission slipping, and axle wear. To diagnose, inspect for clicking sounds during turns (indicating CV joint failure) or fluid leaks near the transmission. If the vehicle vibrates at high speeds, check for worn driveshaft components. Addressing these issues promptly prevents further damage and ensures safe operation.

To optimize drivetrain performance, use high-quality transmission fluid and synthetic lubricants. Regularly inspect and replace worn components such as CV joints and axles. Ensure proper alignment and tire balance to reduce stress on the drivetrain. Upgrading to performance parts, such as a limited-slip differential, can also enhance handling and traction.
