How do you check the manual transmission fluid level on a Toyota Echo?

To check the manual Transmission Fluid level on a Toyota Echo, first ensure the vehicle is on a level surface and the engine is off. Locate the transmission fill plug, which is typically on the side of the transmission case. Remove the plug and insert your finger; the fluid level should be just below the edge of the fill hole. If the fluid is low, add the appropriate type of manual transmission fluid until it reaches the correct level, then replace the fill plug securely.
