How do you check oil on a ml 320 auto gearbox?

To check the oil level in a Mercedes ML320 auto gearbox, first ensure the vehicle is on a level surface and the engine is running at operating temperature. Locate the transmission dipstick, usually found near the back of the engine bay, and pull it out. Wipe it clean, reinsert it fully, then remove it again to check the oil level; it should be within the designated range on the dipstick. If necessary, add the appropriate Transmission Fluid through the dipstick tube to reach the correct level.
