I buy my transmission rebuild kits from TRANSTAR INDUSTRIES INC. The website is here... www.transtarindustries.com
Check, they may have one near your house, you never know. This is where most transmission repair shops get parts. Then they stick it to you for $3800 bucks or more. The parts of your ZF transmission are dirt cheap $550 bucks total for the whole rebuild kit. Unless you just want to fix one little thing and put it back in. In my opinion, the hardest part was taking it off and CLEANING! You have to buy 5 gallans of degreaser and clean alot of **** especially the carrier underneath. Once everything is clean (tools included) it makes the job so much easier. Everything is nice and clean and organized. Buy a big box of disposable rubber gloves too.
If you need Audi Parts (of any kind) there are several Audi-only salvage yards, but my favorite is SHOKAN Coachworks www.shokan.com
If you need a transmission repair manual for your specific Audi Transmission, you can get it at Automatic Transmission Service Group (ATSG) website is here... www.atsg.com
. I have the ZF5HP24A (the letter "A" is for all wheel drive, don't confuse it ) book and I don't need it anymore. It was the best manual I ever seen with good photographs and very simple procedures to dissasemble and reinstall. There was so many little parts and washers and bearrings that I had no clue how they went back in, and the manual shows you clearly and flawlessly.
I have repaired other foreign vehicles in my life, but never an Audi Trany. It is was out on the floor in two days, and I took it apart to inspect the damage. I took the tranny apart CAREFULLY, following step by step instructions.It was a pain in the *** removing the ATF Oil Supply assembly without the Audi shop tool they illustrate. I used a vice grip pliers and a dent puller and hammered it out without a scratch! Flawless! I should have been an engineer my wife said. I had to improvise also with the removal of the clutch pistons to replace the seals.
You don't have to do this if your tranny parts look new and has low mileage, but I did all this work and just don't want to take a chance on a 5 cent rubber ring seal.
By the way, all the parts inside look new. The culprit was clutch pack "B" . That's what they call it in the manual. All the friction plates in clutch pack "B" (6) were burnt almost to the metal. Lucky thing I stopped driving it or it would have been metal to metal grinding going on to destroy more parts. The online subscrition manual goes on to explain that if you are slipping on fourth or fifth gear(doesn't matter), then your converter clutch (integrated with the converter -built in) is failing, causing Clutch pack "B" to overheat. This is probably what is making the transmission control module go into fail safe mode and the car free revs in drive until you shut it off (limp Mode). Don't ask me how that works, I just pulled the clutches apart to inspect them, and the gosh darn manual was right on the money! clutch "b" cylinder looks black and all the friction plates were scorched. So, I need a new torque converter $109 bucks at DACCO of detroit in Orlando(incase you want to buy one) the dealer has them for $1100 bucks(bastards) no one else carries converters in our national chains. And you sure as hell don't want to buy a used one... So, the master rebuild kit cost me $550 bucks, plus I'm changing the oil to Mobil 1 fully synthetic ATF(which is way cheaper, and I can get it at Wal-mart for crying out loud(compared to the dealer's Esso LT 71141 oil).
I will restock it with this ATF Oil. I'm not spending $300 on oil from Germany, when clearly everyone is saying in forums that Audi/Volkswagens/Bmw oil is Dexron IID(worse than Dexron III).
Here is the Mobil website if you want to compare specs. They say their oil exceeds and out performs Audi's. http://www.mobil.com/USA-English/Lub...thetic_ATF.asp
It looks easy to rebuild, You just need alot a patience, Good spec manuals. plenty of room, clean organized area, about three weeks (take your time), an engine hoist $200 at advance auto because you have to support the engine while you remove the entire subframe, lots of desel and degreaser, four jack stands, and two hydraulic jacks(to put it back in I used two Hydaulic jacks and three men to wiggle that monster in and get a bolt started- 15 minutes and alot of muscle) the rest of the work I did myself,It took 4 days little by little putting stuff back in. I am slow, maybe you can do it faster. Oh and you have to have air tools, this really helps. You need torx sockets(these cars use alot of specialty tools, but I improvised) hex sockets, swivels, twelve point torx driver, (to remove the front drive shafts). I already have all these tools because I fix cars and have bought them over the years. But, it is not expensive at all. Compared to $3800 or more at a shop.
Study the manual first. Go over the proceedures in your mind for a day or two. study, all the details, and act the part in your mind. Think about how expensive it will be to tow it to the shop and have them fix it. hopefully you will be motivated like me to drop that tranny and fix it yourself!. Audi maintains value in the market place, it is worth fixing because they are built well. I feel so good and confident now. I can drive this car to Alaska without doubts because I know what's in there. I also changed the oil from Audi's expensive ESSO life time oil(bull **** it was black and dirty), to Mobile 1 synthetic ATF. It it running smooth, I love the power it has now. It shifts flawlessly. You do not have to spend $600 dollars on everything in there, Just buy the frictions and fix what ever clutch pack is burnt out. I noticed that I was taking out seals and they looked new, I was doing double work. It was not neccesary in my case to take every little thing apart and change all those pain in the *** seals and berrings. They look new. It would have been a $50 job if I just bought clutch B frictions and definately have your converter rebuilt or buy a rebuilt one. New ones cost too much. The converter was what caused my problem in my ZF5HP24A
Good luck my friend.
