Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engine is cool.
Disconnect the battery to prevent any electrical issues.

2. Drain Old Transmission Fluid

Locate the transmission fluid drain plug and place a fluid catch pan underneath.
Remove the drain plug using a socket set and allow the fluid to completely drain into the pan.

3. Replace Transmission Filter

If applicable, remove the transmission pan by unbolting it with a socket wrench.
Carefully pry off the pan and discard the old gasket.
Remove and replace the old transmission filter with a new one.

4. Reinstall Transmission Pan

Clean the surface of the transmission and the pan thoroughly to ensure a good seal.
Place a new gasket on the pan and reinstall it, tightening the bolts to the manufacturer’s specified torque (usually around 10-12 ft-lbs).

5. Fill with New Transmission Fluid

Reinstall the drain plug securely.
Using a funnel, fill the transmission with the manufacturer-recommended transmission fluid through the dipstick tube or designated fill port.
Check the fluid level with the dipstick to ensure it is at the proper mark.

6. Test the Transmission

Reconnect the battery.
Start the vehicle and let it idle for a few minutes while checking for leaks.
Shift the transmission through all gears and monitor for any unusual behavior.
