Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, transmission fluid pump, clean rags.
Ensure the vehicle is parked on a level surface and the engine is off.
Allow the transmission to cool down if it has been operating.

2. Drain Old Transmission Fluid

Place a drain pan under the transmission pan.
Remove the transmission pan bolts using a socket set.
Carefully lower the transmission pan to allow the old fluid to drain completely.
Clean the pan and magnet (if equipped) from metal shavings or debris.

3. Replace Transmission Filter (if applicable)

Remove the old transmission filter from the valve body.
Install the new filter, ensuring it is seated correctly and secured as per manufacturer specifications.

4. Reinstall Transmission Pan

Place a new gasket on the transmission pan.
Reattach the pan to the transmission housing using the original bolts.
Torque the bolts to the manufacturer's specified torque settings (typically 10-12 Nm).

5. Add New Transmission Fluid

Use a transmission fluid pump to fill the transmission with new, manufacturer-recommended fluid.
Fill until the fluid level reaches the appropriate mark on the dipstick.
Start the vehicle and cycle through the gears to allow fluid to circulate.

6. Check for Leaks

Inspect the transmission pan and cooler lines for any signs of leaks after filling.
