🔧 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.
