Solution

1. Preparation

Gather tools and materials: OBD-II scanner, socket set, transmission fluid pump, clean rags, new transmission fluid (as per manufacturer's specifications), and a new transmission filter (if applicable).
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid any electrical issues.

2. Drain Old Fluid

Locate the transmission drain plug and place a drain pan underneath.
Remove the drain plug using the socket set and allow the old transmission fluid to drain completely.
Clean the drain plug and inspect for metal shavings or debris.

3. Replace Filter (if applicable)

Remove the transmission pan using a socket set. Note that some fluid may still be in the pan.
Take out the old transmission filter and discard it.
Install the new transmission filter, ensuring it is seated properly.

4. Install Transmission Pan

Clean the transmission pan thoroughly with a solvent to remove old gasket material.
Apply a new gasket or sealant to the transmission pan.
Reattach the pan using the socket set, tightening to the manufacturer's torque specifications.

5. Refill New Fluid

Using the transmission fluid pump, refill the transmission with new fluid through the dipstick tube.
Check the owner's manual for the correct type and amount of transmission fluid.
Start the engine and let it idle, shifting through all gears to circulate the new fluid.
