Solution

1. Preparation

Gather all necessary tools and parts.
Tools Required:
- Socket set
- Torque wrench
- Funnel
- Transmission fluid pump
- Rags for cleanup
Safety Warnings: Ensure the vehicle is parked on a level surface and the engine is cool before starting.

2. Drain Old Transmission Fluid

Place a drain pan under the transmission.
Remove the drain plug with a socket wrench and allow the fluid to completely drain into the pan.
Inspect the old fluid for metal shavings or debris, which may indicate internal wear.

3. Replace the Filter (if applicable)

If the transmission has a serviceable filter, locate and remove it.
Clean the filter mounting surface.
Install a new filter, ensuring it is seated properly.

4. Fill with New Transmission Fluid

Replace the drain plug and torque it to the manufacturer's specifications (usually around 25 Nm).
Using a funnel or transmission fluid pump, add new transmission fluid through the fill plug.
Fill until the fluid begins to slightly overflow from the fill hole, indicating a proper level.

5. Check Fluid Level and Condition

Reinstall the fill plug and torque to specification.
Start the engine and cycle through all gear positions (P, R, N, D) for a few seconds each.
Recheck the fluid level using the dipstick (if applicable) or by checking the fill plug again.
