Solution

1. Preparation

Gather tools and parts: OBD-II scanner, socket set, fluid catch pan, new transmission fluid, funnel, and replacement transmission filter (if applicable).
Ensure the vehicle is parked on a level surface, and the engine is cool.

2. Drain Old Transmission Fluid

Locate the transmission drain plug (refer to the vehicle's service manual for exact location).
Using a socket set, carefully remove the drain plug and allow the old fluid to completely drain into a catch pan.
Replace the drain plug and torque it to the manufacturer’s specifications.

3. Replace Transmission Filter (if applicable)

If the transmission has a filter, remove the transmission pan (if applicable) using a socket set.
Replace the old filter with a new one, ensuring it is properly seated.
Clean the transmission pan and install it back onto the transmission.

4. Add New Transmission Fluid

Using a funnel, pour the new transmission fluid into the fill hole.
Check the manufacturer’s specifications for the correct type of transmission fluid and the recommended amount.
Start the engine and allow it to run for a few minutes while shifting through the gears to circulate the new fluid.

5. Check Fluid Level

With the engine running, recheck the transmission fluid level using the dipstick.
Add more fluid if necessary to reach the recommended level.
