Solution

1. Preparation

Gather tools: socket set, torque wrench, transmission fluid pump, clean rags, and a container for old fluid.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid electrical issues during the repair.

2. Drain Old Transmission Fluid

Position a container under the transmission pan to catch the old fluid.
Remove the transmission pan bolts using a socket set.
Carefully lower the transmission pan, allowing the fluid to drain completely.

3. Replace Transmission Filter

Remove the old transmission filter by unscrewing it or unclipping it, depending on the model.
Inspect the filter housing for debris and clean it as necessary.
Install a new transmission filter, ensuring it is seated correctly.

4. Clean and Reinstall Transmission Pan

Thoroughly clean the transmission pan and remove any old gasket material.
Apply a new gasket or a thin layer of RTV silicone sealant to the pan.
Reattach the transmission pan and torque the bolts to the manufacturer's specifications.

5. Refill with New Transmission Fluid

Use a transmission fluid pump to fill the transmission with the correct type of new fluid as specified in the owner’s manual.
Start the engine and let it run for a few minutes, cycling through the gears.
Check the fluid level again using the dipstick and add more fluid if necessary.
