🔧 Outback - Manual Transmission Fluid Change

Your Outback’s manual transmission uses gear oil that lubricates the gears and bearings. Changing it is a drain-and-refill job, but the correct plug locations, fluid amount, and torque specs depend on which manual transmission you have.

Difficulty Level: Intermediate | Estimated Time: 1-2 hours

⚠️ Safety & Precautions

• ⚠️ Work on a flat surface and support the car with jack stands, not just a jack.
• ⚠️ Let the drivetrain cool; gear oil and exhaust parts can burn you.
• ⚠️ Keep the car level while draining/filling or the level will be wrong.

📋 Before You Begin

• Warm the drivetrain with a 10-minute drive so the fluid drains better.
• Park on level ground, shut off the engine, and chock the rear wheels.
• Lift and support the front of the car so it stays level.
• Quick questions so I give you the exact plug locations, capacities, and torque specs:
  • Is your manual transmission a 6-speed or 5-speed?
  • Are you changing only the transmission/front differential fluid, or also the rear differential fluid?
