Solution

1. Preparation

Gather tools and materials.
Disconnect the vehicle battery to prevent any electrical shorts.
Raise the vehicle securely on jack stands.

2. Drain Transmission Fluid

Place a drain pan under the transmission.
Remove the transmission pan bolts using a socket set.
Carefully lower the transmission pan and allow the fluid to drain completely.
Clean the pan and magnet inside to remove metal shavings.

3. Replace Transmission Filter

Remove the old transmission filter by unscrewing it.
Install the new filter, ensuring it’s securely in place.
Replace any O-rings if applicable.

4. Reinstall Transmission Pan

Clean the mating surfaces on the transmission and the pan.
Install a new gasket or apply gasket maker as per manufacturer specifications.
Reattach the transmission pan, tightening the bolts to the specified torque (generally around 8-10 Nm).

5. Refill Transmission Fluid

Using a funnel, refill the transmission with the appropriate type and amount of fluid (refer to the owner’s manual, typically around 8-10 quarts of ATF).
Start the engine and allow it to reach operating temperature, shifting through all gears.

6. Check for Leaks and Adjust Fluid Level

While the engine is running, check for any leaks around the pan and filter.
If necessary, add fluid to reach the proper level on the dipstick.
