Reinstall Drain Plug: Replace and securely tighten the drain plug using a torque wrench to the manufacturer's specified torque.
Add New Fluid: Using a funnel, add new transmission fluid through the dipstick tube. Refer to the owner’s manual for the correct type and amount of fluid.
Check Fluid Level: Start the vehicle and let it idle for a few minutes. Shift through all gears and check the fluid level again, adding fluid as necessary.
