2. Drain Transmission Fluid

Raise the Vehicle: Use a jack to lift the vehicle and secure it with jack stands.
Locate the Drain Plug: Identify the transmission drain plug on the bottom of the transmission pan.
Remove the Drain Plug: Using the appropriate socket, carefully loosen and remove the drain plug, allowing the fluid to drain into a drain pan. Note the condition of the fluid.
Replace Drain Plug: Once the fluid has fully drained, clean the drain plug and install a new sealing washer. Reinstall and torque to the manufacturer’s specifications (typically around 30-40 lb-ft).

3. Replace Transmission Filter (if applicable)

Remove Transmission Pan: If the filter is accessible from the pan side, remove the transmission pan by loosening the bolts. Carefully lower the pan, allowing any remaining fluid to drain.
Replace Filter: Remove the old transmission filter from its housing, noting any orientation. Install the new filter, ensuring it is seated properly.
Clean Transmission Pan: Clean the pan thoroughly, removing any debris or old gasket material. Install a new gasket if required.

4. Refill Transmission Fluid

Reinstall Transmission Pan: Replace the transmission pan and torque the bolts to specifications, ensuring a proper seal.
Fill Transmission Fluid: Locate the transmission fill port. Using a funnel or transmission fluid pump, add the new transmission fluid as specified in the owner’s manual.
Check Fluid Level: Start the engine and allow it to reach operating temperature. With the vehicle in park or neutral, check the fluid level on the dipstick, adding more fluid as necessary.
