Do you have tools? You will need a basic set for this job. Not overly elaborate, but assorted metric sockets and all in 3/8 drive will be fine, some assorted end-wrenches, probably screwdrivers, and several very large assorted hammers (Just kidding on the hammers) Then you need to got to thee dealer. Your local parts house is not going to have a transmission pan for that car. Write down your VIN and bring it with you. Get a pan and gasket. Then go to the parts store and buy jack-stands. And If you choose, a creeper to lie on. Now idk what you mean by 'connector tube' but cooling line? It will unscrew from trans, it has a swivel. I will try to find a diagram of where the fluid (Oh bty buy the fluid while you are at dealer they will have proper kind) A word of caution 1) Do NOT get under a jacked up non-supported car. OK (2 words) Idk the extent of damage but if the pan just got punctured you may want to go ahead and tackle this. Don't plan anything else for the day. But if the pan is really crunched up in to the innards of the trans... do as you please but you might re-consider starting this. Best wishes

The Quattro is a unique animal. They are hard to work on, you could not have chosen a worse car for this to happen. They have all sorts of (to me) unknown lines wires and what-nots. Even in 1994. Matter of fact I had one in the early 90's until one day my then-5year old decided to fill up the gas tank with the water hose. Then my (then) wife pulled out the hose, did not tell me and proceeded to start the car and drive away. She got to the end of the block, and the car ...even $1500 later was never the same

Thanks for the fast answer. I already took the pan off, no damage inside the tranny. I guess the cooler line then, that got smashed and isn't salvageable so I need to remove it as well. So I basically need to know how to remove that, and add fluid to it. I'm working on getting a pan out of an Audi boneyard. Yeah, I knew as soon as I saw I hit transmission that I was in for a world of hurt. That picture is really beneficial; I was having trouble understanding what people were saying. I intend on buying a new gasket set of course and putting in a new filter. Are you familiar with the process of filling the fluid and checking it? I know it has to be on a level service and needs to "dribble" out of the fill hole. But I don't know the steps I should be taking.

I just got it. It's had a ton of work done on it so it's definitely worth it to put a new pan on.

i had a audi 100 once it was a 91 was a smart little pearl white car. Traded an old 84 5000 for it :P mine was only a single not a quattro tho but was fun to play with none the less. Any ways i am not so sure bout the older modal vw's and audis but the ones past 96 required the trany to be in gear and in motion to fill properly. any ways if your loacated in the states i would recomend this website for seals if they have them also they have at the link i am posting after this with a step by step how to guide with pictures for your car (fyi the trany pan on that one is scraped as well so seems a design flaw to me.)
