Subaru Subaru Legacy 2020-present Drivetrain Specifications

The 2020-Present Subaru Legacy offers two drivetrain options: a standard 2.5L 4-cylinder engine producing 182 hp and a 2.4L turbocharged 4-cylinder engine generating 260 hp. Both engines are paired with a Lineartronic CVT (Continuously Variable Transmission) and Subaru's Symmetrical All-Wheel Drive system, ensuring optimal traction and performance in various driving conditions.

The Subaru Legacy's drivetrain requires regular maintenance, including CVT fluid changes every 30,000-60,000 miles, differential fluid replacement every 30,000 miles, and routine inspections of the AWD system. Additionally, ensure the engine oil is changed every 6,000 miles or 6 months, and the air filter is replaced every 12,000-15,000 miles to maintain optimal performance.

To replace the CVT fluid, first, lift the vehicle and secure it on jack stands. Locate the CVT fluid drain plug underneath the transmission and remove it to drain the old fluid. Reinstall the drain plug and refill the CVT fluid through the dipstick tube using the manufacturer-recommended fluid. Start the engine, shift through all gears, and check the fluid level to ensure proper filling.

If the AWD system malfunctions, check for warning lights on the dashboard. Inspect the AWD system's fuses and relays, and ensure the tires are of the same size and tread depth. If the issue persists, use a diagnostic tool to scan for error codes and consult the service manual for specific troubleshooting steps or visit a certified Subaru technician.

To optimize drivetrain performance, use high-quality synthetic fluids for the engine, transmission, and differential. Regularly inspect and replace worn-out components like belts and hoses. Ensure proper tire inflation and alignment, and avoid aggressive driving to reduce strain on the CVT. Consider upgrading to performance air filters and exhaust systems for improved efficiency.
