Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off and cool.
Disconnect the battery to prevent electrical shorts.

2. Drain Old Transmission Fluid

Place a drain pan under the transmission pan.
Remove the transmission pan bolts using a socket set, starting from the rear to avoid splashing.
Allow the fluid to fully drain into the pan.

3. Replace Transmission Filter

Remove the old transmission filter by unscrewing it; be cautious of residual fluid.
Install the new transmission filter, ensuring it is secured properly.

4. Clean Transmission Pan

Clean the transmission pan thoroughly to remove any debris or sludge.
Inspect the pan for damage or wear, and replace if necessary.

5. Reinstall Transmission Pan

Apply a new gasket or sealant as recommended by the manufacturer.
Reattach the transmission pan and torque the bolts to the manufacturer's specifications (typically around 10-12 ft-lbs).

6. Refill with New Transmission Fluid

Use the manufacturer-recommended transmission fluid type.
Pour the new fluid into the transmission through the dipstick tube using a funnel.
Check the fluid level and add more if necessary.

7. Test Drive and Check for Leaks

Reconnect the battery and start the engine.
Allow the vehicle to warm up and shift through all gears.
Inspect for any leaks around the transmission pan and cooler lines.
