Mitsubishi Mitsubishi Eclipse 2006-2012 Drivetrain Specifications

The drivetrain for the 2006-2012 Mitsubishi Eclipse is available in both front-wheel drive (FWD) and all-wheel drive (AWD) configurations, depending on the trim level. The base models typically feature a 2.4L inline-4 engine paired with a 4-speed automatic or 5-speed manual transmission. The GT trim includes a 3.8L V6 engine with a 5-speed automatic or 6-speed manual transmission. Compatibility is limited to these specific models and trims, and aftermarket parts must match these specifications for proper fitment and performance.

Regular maintenance for the drivetrain includes checking and replacing the transmission fluid every 30,000 to 60,000 miles, depending on driving conditions. Inspect the driveshaft and CV joints for wear and tear every 15,000 miles. Differential fluid should be replaced every 50,000 miles. Regularly check for leaks and ensure all components are properly lubricated. Follow the manufacturer’s guidelines for specific intervals and use only recommended fluids and parts to maintain optimal performance and longevity.

To replace drivetrain components, first, safely lift the vehicle using a jack and secure it on jack stands. Remove the wheels to access the CV axles and driveshaft. Disconnect the transmission linkage and exhaust system if necessary. Unbolt the driveshaft and CV axles, then carefully remove them. Install the new components in reverse order, ensuring all bolts are torqued to manufacturer specifications. Refill any drained fluids and test the vehicle for proper operation. Always refer to the service manual for detailed instructions.

Common drivetrain issues include unusual noises, vibrations, or difficulty shifting. Start by inspecting the CV joints and driveshaft for damage or wear. Check the transmission fluid level and condition, as low or degraded fluid can cause performance issues. Look for leaks around the differential and transmission. If vibrations are present, ensure the driveshaft is balanced and properly aligned. For persistent issues, consult a professional mechanic or refer to the service manual for advanced diagnostics.

To optimize drivetrain performance, use high-quality synthetic fluids for the transmission and differential. Regularly inspect and maintain all drivetrain components to prevent wear and tear. Upgrade to performance parts such as reinforced CV axles or a lightweight driveshaft for improved handling and acceleration. Ensure the vehicle is properly aligned and balanced to reduce strain on the drivetrain. Avoid aggressive driving habits that can cause excessive wear and always follow the manufacturer’s maintenance schedule.
