Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery (negative terminal) to prevent electrical issues.

2. Drain Old Transmission Fluid

Tools Required: Socket set, fluid catch pan, funnel.
Place a fluid catch pan under the transmission pan.
Remove the transmission pan bolts with the socket set and gently pry off the pan to drain the old fluid completely.

3. Replace Transmission Filter

Remove the old filter from the transmission by unbolting it.
Install the new transmission filter, ensuring it is seated properly.
Torque the filter bolts to the manufacturer's specifications (typically around 10-15 Nm, verify specifics).

4. Clean and Reinstall Transmission Pan

Clean the transmission pan and remove any debris or old gasket material.
Install a new gasket or use RTV sealant as recommended.
Reattach the transmission pan and torque bolts to the specified value (usually around 10-12 Nm).

5. Refill with New Transmission Fluid

Tools Required: Funnel.
Using the funnel, refill the transmission with the manufacturer-recommended fluid type (typically ATF). Ensure to fill to the correct level according to the dipstick or manufacturer's specifications.

6. Test and Check for Leaks

Reconnect the battery.
Start the vehicle and let it warm up. Check the fluid level and add more if necessary.
Inspect for any leaks around the transmission pan.
