Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, transmission fluid pump, funnel, clean containers for fluid.
Ensure the vehicle is on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical shorts.

2. Change Transmission Fluid

Drain Old Fluid
- Place a clean container under the transmission pan.
- Remove the transmission pan bolts using the socket set.
- Carefully lower the pan and allow the fluid to drain completely.
Replace Filter
- Remove the old transmission filter from the valve body. Ensure the O-ring comes off with the filter.
- Install the new transmission filter, ensuring it is seated properly.
Clean Pan and Magnet
- Clean the transmission pan thoroughly and remove any debris.
- Inspect the magnet for metal shavings and clean it.
Reinstall Pan
- Install a new gasket on the transmission pan.
- Reattach the pan and torque the bolts to the manufacturer's specifications (check service manual for specific torque values).

3. Refill Transmission Fluid

Add New Fluid
- Use a funnel to add the recommended type of transmission fluid through the dipstick tube.
- Refer to the owner’s manual for the specific fluid type and required amount.
Check Fluid Level
- Start the engine and let it run for a few minutes while shifting through all gears.
- With the engine running, check the fluid level on the dipstick and adjust as necessary.

4. Reconnect Battery

Reconnect the battery terminals, ensuring they are secure.
