How to Change the Transmission Oil in an Automatic Audi TT 2993
The automatic transmission fluid in the Audi TT should be changed every 30,000 miles or three years, whichever comes first. The transmission fluid gets contaminated with tiny, metal slivers and clutch material that wears off the internal workings of the transmission as it is used over time. The transmission pan has a magnet in the bottom of it to catch most of the metal to keep it from being drawn back up into the valve body. The passages in the valve body are small and easily clogged.

Raise the vehicle with the floor jack and support it with jack stands. Slide the drain pan under the transmission. Remove the bolts, except for two bolts in one corner, on the transmission pan, using the appropriate socket. The pan will tip and most of the fluid will drain into the drain pan.

Remove the last two bolts and take the pan off the transmission. Clean the inside of the pan, magnet and gasket-mounting surfaces thoroughly, using the scraper and rag. Rinse the inside of the pan and the magnet with carburetor cleaner, then wipe everything with a clean rag.

Unbolt the transmission filter, using the appropriate socket. Discard the filter. Install the new filter. Fit the gasket to the transmission pan. Install the pan, ensuring that the gasket stays completely in line, and that the bolts go through the pan and the gasket, into the bottom of the transmission. Tighten the bolts firmly, but do not overtighten them and squash the gasket.

Lower the vehicle off the jack stands. Insert the funnel into the transmission dipstick tube. Pour 5 qts. of automatic transmission fluid into the pan. Start the vehicle and run it through the gears -- Reverse, Drive, Second and First -- at least twice. Leave the car running, and allow it to get to operating temperature.

Check the level of the transmission fluid on the dipstick. Top off with automatic transmission fluid as needed, 1 pt. at a time, and shift through the gears after every addition. Depending on the torque converter in the transmission, it could take up to 7.6 qts.
