2001 A4 1.8T Quattro, automatic transmission, 135 000km.

Hello, I have just purchased this vehicle and love it, its in mint condition and has been kept up in good shape it seems. I would like to know how many different fluids it has and what kind are they. Where can i find that info i have been looking online but no luck. I know of rear diff, front diff, brake, rad, i think transfer case is the transmission fluid also correct me if you know.

Thank you.
