Solution

1. Preparation

Gather tools: socket set, transmission fluid pump, OBD-II scanner, and a container for old fluid.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Drain Old Transmission Fluid

Locate the transmission fluid pan or drain plug.
Place a container under the transmission to catch the old fluid.
Remove the drain plug or pan bolts and allow the fluid to completely drain out.
Inspect the old fluid for metal shavings or debris, which may indicate internal damage.

3. Replace Transmission Filter (if applicable)

Remove the transmission pan (if necessary) to access the filter.
Replace the old filter with a new one, ensuring proper alignment.
Clean the mating surfaces of the transmission pan and the transmission.

4. Refill with New Transmission Fluid

Use a funnel or fluid pump to add new transmission fluid through the dipstick tube or designated fill port.
Refer to the owner's manual for the correct type and amount of transmission fluid required.
Start with about 75-80% of the required amount, then check the level using the dipstick.

5. Check and Test

Start the engine and let it idle for a few minutes, then shift through all gears.
Recheck the fluid level and add more fluid if necessary to reach the correct level.
Look for leaks around the transmission pan and lines after refilling.
