Were do you add transmission fluid in a 98 Cabrio?

On the VW automatic transmission of this generation vehicle, the transmission is supposed to be serviced only by VW, so there is not the typical dip stick tube that comes up into the engine compartment. You can check the fluid and add if needed through the fill spout, under the car, located directly on the transmission pan. There is a short 2" tube with a red cap, unscrew the cap which also has a fluid level indicator attached, similar to a power steering dipstick. To add fluid you will need to pump it in with a hose attached to your container. Regards. BDBENZ
