How do you check transmission fluid on a 2007 Jetta?

To check the Transmission Fluid on a 2007 Jetta, first ensure the engine is warm and running. Locate the transmission dipstick, usually found near the back of the engine compartment, and remove it. Wipe it clean, reinsert it fully, and then remove it again to check the fluid level, which should be within the marked range. If necessary, add the appropriate type of transmission fluid through the dipstick tube.
