Solution

1. Preparation

Gather tools and materials: socket set, transmission fluid, funnel, new transmission filter, pan gasket, and a drain pan.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Drain Transmission Fluid

Place the drain pan under the transmission pan.
Remove the transmission pan bolts using the socket set and carefully lower the pan to drain fluid.
Dispose of old fluid according to local regulations.

3. Replace Transmission Filter

Remove the old transmission filter by unscrewing it from the valve body.
Install the new transmission filter, ensuring it is seated correctly.

4. Clean and Reinstall Transmission Pan

Clean the transmission pan and remove any old gasket material.
Apply a new gasket to the pan and torque the bolts to the manufacturer’s specifications (usually around 10-15 lb-ft).

5. Refill Transmission Fluid

Using a funnel, refill the transmission with the appropriate type of fluid specified in the owner’s manual.
Start the engine and allow it to reach operating temperature while checking fluid levels.

6. Test Drive

Test drive the vehicle to ensure proper operation and check for any leaks.
