Solution

1. Preparation

Tools Required:
- Socket set
- Torque wrench
- Funnel
- Clean catch pan
- Transmission fluid dipstick
Safety Warnings:
- Ensure the vehicle is on a level surface.
- Allow the transmission to cool down before working on it.

2. Drain Old Transmission Fluid

Place a clean catch pan under the transmission drain plug.
Remove the drain plug using a socket wrench and allow the old fluid to completely drain into the catch pan.
Once drained, replace and torque the drain plug to the manufacturer’s specifications (typically around 10-20 lb-ft).

3. Replace Transmission Filter (if applicable)

Remove the transmission pan by unscrewing the bolts with a socket wrench.
Carefully lower the pan and remove the old transmission filter.
Install the new filter, ensuring it is seated properly.

4. Refill with New Transmission Fluid

Using a funnel, refill the transmission with new, manufacturer-recommended fluid (check the owner's manual for specific type).
Start with the specified amount, typically around 4-8 quarts, depending on the model and whether the fluid is being changed or topped off.

5. Check Fluid Level

Start the engine and let it idle for a few minutes.
Shift through all gears and return to park.
Check the fluid level using the dipstick and add more fluid if necessary.
