Solution

1. Preparation

Gather tools: socket set, torque wrench, funnel, fluid pump, and a drain pan.
Ensure the vehicle is on level ground and the engine is cool.
Disconnect the negative battery terminal to prevent electrical issues.

2. Drain Old Transmission Fluid

Place the drain pan under the drain plug.
Remove the drain plug using the appropriate socket, allowing the old fluid to fully drain into the pan.
Clean the drain plug and inspect for metal shavings or debris.

3. Replace Transmission Filter (if applicable)

Locate the transmission filter (if the model has one).
Remove the old filter using a socket or wrench.
Clean the mounting surface for the new filter.
Install the new filter according to the manufacturer's specifications.

4. Fill New Transmission Fluid

Replace and torque the drain plug to the manufacturer’s specifications (typically 30-40 ft-lbs).
Locate the fill port, usually on the top of the transmission.
Use a funnel and fluid pump to fill the transmission with new fluid until it reaches the specified level (check the owner's manual for exact capacity).
Ensure to use the correct type of transmission fluid (typically CVT fluid for Subaru).

5. Final Checks

Start the engine and let it run for a few minutes while cycling through all gears.
Recheck the fluid level and add more fluid if necessary.
Reconnect the negative battery terminal.
