Mitsubishi Mitsubishi Endeavor 2004-2011 Drivetrain Specifications

The Mitsubishi Endeavor (2004-2011) features a front-wheel-drive (FWD) system, with an optional all-wheel-drive (AWD) variant. The AWD system uses a center differential to distribute power between the front and rear axles. The drivetrain is paired with a 3.8L V6 engine, producing 225-230 horsepower and 255-255 lb-ft of torque. The transmission is a 4-speed automatic. The AWD system is compatible with various terrains but is not designed for heavy off-roading.

Regular maintenance for the Endeavor's drivetrain includes checking and replacing the transfer case fluid every 30,000 miles, inspecting the driveshaft and CV joints for wear, and ensuring the AWD system’s sensors are functioning properly. The differential fluid should be changed every 50,000 miles. Additionally, the transmission fluid and filter should be replaced every 60,000 miles to ensure optimal performance and longevity.

To replace drivetrain components, first, lift the vehicle securely on a jack stand. Remove the wheels and disconnect the driveshaft. For the transfer case, drain the fluid, unbolt it, and replace it with a new unit. For the differential, remove the cover, drain the fluid, and replace the gears if necessary. Reassemble all components, refill with the appropriate fluids, and test the system for proper operation.

If the AWD system malfunctions, check for error codes using an OBD-II scanner. Inspect the transfer case fluid level and quality. Ensure the AWD sensors and wiring are intact. If the issue persists, test the transfer case motor and control module. Common solutions include replacing faulty sensors, repairing wiring, or servicing the transfer case. Consult a professional if the problem remains unresolved.

To optimize drivetrain performance, use high-quality synthetic fluids for the transmission, transfer case, and differential. Regularly inspect and replace worn components like CV joints and driveshafts. Ensure tires are properly inflated and aligned to reduce strain on the drivetrain. Consider upgrading to performance-grade parts if available. Avoid excessive towing or off-roading to prevent unnecessary wear.
