Solution

1. Preparation

Tools Required: OBD-II scanner, fluid siphon pump, clean containers, funnel, safety goggles, gloves.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts during the repair.

2. Drain the Old Transmission Fluid

Locate the transmission drain plug.
Place a clean container under the transmission pan to catch the fluid.
Remove the drain plug and allow the fluid to fully drain into the container.
Dispose of the old fluid according to local regulations.

3. Replace the Transmission Filter

Remove the transmission pan by loosening the bolts with a socket set.
Carefully lower the pan and remove the old filter.
Install the new transmission filter, ensuring it is seated properly.
Clean the transmission pan and the mating surface on the transmission.

4. Reassemble and Refill Transmission Fluid

Reinstall the transmission pan, tightening the bolts to the manufacturer's specified torque (typically around 10-12 lb-ft).
Refill the transmission with new fluid through the dipstick tube using a funnel (consult the owner's manual for the correct fluid type and capacity).
Start the engine and let it run for a few minutes, then shift through all gears to circulate the new fluid.

5. Final Checks

Check the fluid level again with the dipstick and add more fluid if necessary.
Inspect for leaks around the transmission pan and cooler lines.
Reconnect the battery.
