Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Raise the vehicle using a jack and secure it with jack stands.

Tools Required:

Socket set
Torque wrench
Transmission fluid pump
Drain pan
Funnel
OBD-II scanner (for preliminary checks)

2. Drain the Old Transmission Fluid

Locate the transmission fluid drain plug.
Using the socket set, carefully remove the drain plug and allow the old fluid to drain into the drain pan.
Replace the drain plug and torque it to the manufacturer’s specified value (consult the owner's manual).

3. Replace the Transmission Filter (if applicable)

Remove the transmission pan by unscrewing the bolts with the socket set.
Carefully take off the pan and set it aside.
Remove the old transmission filter and replace it with a new one, ensuring it fits snugly.
Clean the transmission pan and replace the gasket if necessary.

4. Add New Transmission Fluid

Using a funnel, pour the appropriate type and amount of new transmission fluid into the transmission through the dipstick tube or designated fill port.
Start the engine and let it idle for a few minutes, allowing the new fluid to circulate.

5. Check Fluid Level

With the engine running and the transmission in park, use the dipstick to check the fluid level.
Add more fluid if necessary to reach the recommended level.
