Solution

1. Preparation

Tools Required: Socket set, OBD-II scanner, infrared thermometer, fluid catch pan.
Ensure the vehicle is on a level surface and the engine is off and cool.
Disconnect the negative battery terminal for safety.

2. Drain Old Transmission Fluid

Place a fluid catch pan under the transmission oil pan.
Remove the transmission pan bolts using a socket wrench.
Carefully lower the transmission pan and allow the old fluid to drain completely.

3. Inspect and Replace Transmission Filter

Remove the old transmission filter by disconnecting any retaining clips or screws.
Install a new transmission filter, ensuring it is properly seated and secured.

4. Clean Transmission Pan

Clean the transmission pan thoroughly using a suitable degreaser.
Remove any old gasket material from the pan and the transmission casing.

5. Install New Gasket and Transmission Pan

Place a new gasket on the transmission pan.
Reinstall the pan and torque the bolts to the manufacturer's specifications (usually around 10-12 Nm, but check service manual for exact values).

6. Fill with New Transmission Fluid

Use a funnel to pour the appropriate type of new transmission fluid (refer to owner's manual for specifications) into the transmission filler tube.
Start with the recommended amount and check levels with the dipstick.

7. Final Checks

Reconnect the negative battery terminal.
Start the engine and allow it to warm up.
Check for leaks around the pan and verify fluid level again, adding more if necessary.
