Infiniti M35 2006-present Drivetrain Specifications

The 2006-Present Infiniti M35 features a rear-wheel-drive (RWD) or optional all-wheel-drive (AWD) system. It is powered by a 3.5L V6 engine producing 275-303 horsepower, paired with a 5-speed or 7-speed automatic transmission. The drivetrain is designed for smooth performance and optimal fuel efficiency. Compatibility includes Infiniti M35 models from 2006 onwards, with minor variations depending on the model year and trim.

Regular maintenance for the Infiniti M35 drivetrain includes checking and replacing transmission fluid every 30,000-60,000 miles, inspecting the driveshaft and differential for wear, and ensuring proper alignment. The AWD system requires periodic fluid changes for the transfer case and rear differential. Follow the manufacturer's recommended schedule for optimal performance and longevity.

To replace drivetrain components, first, lift the vehicle securely. For the driveshaft, remove the bolts connecting it to the differential and transmission. For the differential, drain the fluid, remove the axles, and unbolt the housing. Installation is the reverse process. Use a torque wrench to ensure proper bolt tightness and refill fluids as specified in the service manual.

Common issues include vibrations, unusual noises, or fluid leaks. Vibrations may indicate a worn driveshaft or unbalanced tires. Noises could point to failing U-joints or differential problems. Leaks often stem from worn seals. Diagnose by inspecting components, checking fluid levels, and performing a road test. Replace damaged parts and ensure proper lubrication.

To optimize performance, use high-quality synthetic fluids for the transmission and differential. Regularly inspect and replace worn components like bushings and mounts. Ensure proper tire alignment and balance. Consider upgrading to performance parts like a limited-slip differential for improved handling and traction.
