It is important to check and maintain fluid levels in a car. To check the Transmission Fluid, a person looks for the red cap under the hood, this is the transmission dipstick.
You don't, it is "lifetime."
You have to take it to the dealership to be check. It has to be at a set temp. to check, with a special tool.
To check the transmission fluid on a 2001 Audi, 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 remove it. Wipe it clean, reinsert it, and then remove it again to check the fluid level; it should be within the marked range. If low, you can add the appropriate transmission fluid through the dipstick tube.
if you cant get the car on ramps forget it
My recommendation is every 36,000 miles. Check your owner's manual for the manufactures recommendation.

To change the transmission fluid on a 2001 Audi A6 2.7, start by warming up the engine and then lift the vehicle securely. Remove the transmission pan to drain the old fluid, and replace the filter if applicable. Reinstall the pan with a new gasket, fill the transmission with the appropriate type and amount of new fluid through the dipstick tube, and check the fluid level while the engine is running. Lastly, ensure there are no leaks and the fluid is at the correct level.
Not needed- semi-permanent.
If its a tiptronic, its "permanent." If you have transmission problems, best take it to a VW/Audi tech.
