Materials Needed

Before starting the process of changing the CVT fluid, you will need to gather the following materials:

  • 5-7 quarts of Subaru CVT fluid (check your owner’s manual for the correct fluid type)
  • A funnel
  • A drain pan
  • A socket wrench set
  • An oil filter wrench
  • A car jack and stands
  • A torque wrench
  • A new oil filter
  • Rubber gloves and safety glasses

Step-by-Step Guide

Here are the steps to change Subaru Outback CVT fluid:

Step 1: Lift the Vehicle

To start, you will need to lift your Subaru Outback off the ground with a jack and jack stands. Make sure the vehicle is level and secure before proceeding. Remember to wear safety glasses and gloves while working.

Step 2: Locate the Drain and Fill Plugs

Locate the drain plug and fill plug on the CVT transmission. The drain plug is located on the pan’s bottom, while the fill plug is located on the side of the transmission.

Step 3: Drain the Old Fluid

Place the drain pan under the drain plug and use the socket wrench to remove the plug. Allow the old fluid to drain out entirely before replacing the plug.

Step 4: Replace the Oil Filter

While the fluid is draining, remove the oil filter using the oil filter wrench. Replace the old filter with a new one, making sure to lubricate the new filter’s gasket with a small amount of transmission fluid.

Step 5: Add New Fluid

Insert the funnel into the fill plug hole and start pouring the new fluid into the transmission. Make sure to use the correct amount of fluid specified in your owner’s manual.

Step 6: Torque the Fill Plug

Use the torque wrench to tighten the fill plug to the manufacturer’s recommended torque specification.

Step 7: Lower the Vehicle and Test Drive

After adding the new fluid, lower the vehicle and take it for a test drive to make sure everything is working correctly.

Flushing the CVT System

While changing the CVT fluid is an essential maintenance task, flushing the system is a more thorough process that is recommended every 60,000 miles. Flushing the CVT system replaces all of the old fluid with new fluid, ensuring that the transmission is clean and running smoothly.

To flush the CVT system, you will need to use a transmission flush machine, which can be purchased or rented from auto parts stores.
