Solution

1. Preparation

Tools Required:
- Socket set
- Torque wrench
- Fluid pump
- Drain pan
- Funnel
- Safety gloves and goggles
Sub-steps:
1. Park the vehicle on a level surface and engage the parking brake.
2. Allow the engine to cool completely.
3. Gather all necessary tools and materials for the fluid change.

2. Drain Old Transmission Fluid

Locate the transmission fluid drain plug underneath the vehicle.
Using the socket set, carefully remove the drain plug and allow the old fluid to drain completely into the drain pan.
Inspect the drain plug for metal shavings or debris and clean it if necessary.

3. Replace Transmission Filter (if applicable)

If your model is equipped with a transmission filter, locate the filter assembly.
Remove any retaining bolts and detach the filter.
Install the new filter, ensuring it is seated properly, and secure it with bolts to the manufacturer’s torque specifications.

4. Add New Transmission Fluid

Reinstall the drain plug and tighten it to the manufacturer's torque specifications.
Using the fluid pump, fill the transmission with new transmission fluid through the dipstick tube or designated fill point.
Refer to the owner's manual for the specific type of transmission fluid and the correct amount needed.

5. Cycle Through Gears

Start the engine and let it idle.
With the brake pedal pressed, cycle through all the gear positions (P, R, N, D) several times to circulate the new fluid.
Check the fluid level using the dipstick, adding more fluid if necessary.

6. Final Checks

Inspect for any leaks around the drain plug and filter.
Ensure that all tools are removed from under the vehicle.
