msey Posted September 27, 2004 Report Share Posted September 27, 2004 I know that this has been brought up alot of time before, with regard to changing Oil, but managed to get this info. this is direct from ZF themselves, and they should know they build the thing. >>Response from ZF Industries: >>Thank you for your interest in ZF Industries, Inc., especially in the spare parts program for 4HP24A 4-speed automatic transmissions for Audi applications. >>First, I would like to apologize for the delay, but your email was moved within the ZF organization until it reached me. >>In regards to your inquiry about replacing the lubricant in your ZF transmission, ZF does recommend to replace the oil after 100,000 miles. Your vehicle should have a 1055000010 or 1055000029 transmission specification and for that transmission you need a Shell type oil with the ZF part number S671090149 (20 liter canister). Please verify the transmission specification (on the metal type plate on the main housing) before contacting any independent distributor. My main question is that I am going to carry out a service on the 4HP24A (4 speed transmision), and I am struggling to find out how much oil I will need for this. I have seen the article on Audipages, but this relates to the 5 speed box, and was wondering if there was a difference. The only reason that I ask this is that I have an Audi Manual and it states 3L for a Filter change. This seems very low considering the 5 speed box on AudiPages says 8 Quaters. Sorry to ask but anyone got more info? Thanks. Link to comment Share on other sites More sharing options...
cruiser647 Posted September 27, 2004 Report Share Posted September 27, 2004 Not sure if this is any good, BUT on my old Audi V8 quattro, it had a 4 spd box. I changed the fluid myself. It was much easier than on the newer 5 spd boxes. I used Castrol Dextron G. I bought 6 litres. I did not take the belly pan off, just drained it and refilled it. It took 5 litres. However, that was not a complete emptying of it, as I did not put the car in gear nor disconnect a hose from the gearbox cooler. The ETKA pic of the gearbox looks the same from my old V8 to your model. Not sure of the part number though. Defo change it! Link to comment Share on other sites More sharing options...
Botang Posted September 27, 2004 Report Share Posted September 27, 2004 Ill find out for you later, it wasnt so long ago I changed the fluid on my 4 speed A8, I assume you have the same CML gearbox code (i'm not familiar with the ZF codes) CML will appear on your sticker in the front of your service boot or alternatively another copy should be stuck in you spare wheel well.

Sven Posted September 27, 2004 Report Share Posted September 27, 2004 [ QUOTE ] I have an Audi Manual and it states 3L for a Filter change. This seems very low considering the 5 speed box on AudiPages says 8 Quaters. Sorry to ask but anyone got more info? Thanks. [/ QUOTE ] It also says the initial fill is 9.6 liters. They don't take of the pan in normal oil changes, so that'll be where the 3 liters come from. (Imagine calling replacing less than 1/3 of the capacity an oil change) You won't get everything out either way, but using Paul's method will probably get you ¾ or thereabout. That's better already. If you'd want to get everything out, the way would be to do this again in a few K miles. Do check, but IIRC 4HP24A is CML. Link to comment Share on other sites More sharing options...
msey Posted September 28, 2004 Author Report Share Posted September 28, 2004 Thanks for the info. Yes the gearbox is a CML one. From an inspection underneath the beast, this looks like it may be easier that the 5 speed one, as the CAT's do not get in the way. Will order 9L just to be on the safe side. Thanks again.

PaulW Posted September 29, 2004 Report Share Posted September 29, 2004 If you want to take a few pictures during the change out, we could make a procedure on audipages with it for the euro people out there with the 4 speed autoboxes! Link to comment Share on other sites More sharing options...
msey Posted October 4, 2004 Author Report Share Posted October 4, 2004 Well have completed the transmission oil change this weekend. Will try and post some pictures up on it. On the 4 speed box there is a drain plug (bottom of Sump) and also a refill plug (on the side of the gearbox sump). Only takes 3 Litres of ATF to do a drain and re-fill. Double checked this on the technical manual supplied by Audi and it was correct. Also it does not have a filter. All it has is a couple of mangnets in the sump, and a rubber gasket. The sump has 6 bolts holding it on. These are 10M sockets (best if you have a 3/8th Socket Set). The re-fill is a 22M spanner, and the Sump plug is a 17M allen Key. Problem is that if you were to do this properly you should remove one of the CAT's to get the sump fully out and flushed. This looked like a real job as the bolts were rusted in (on the CAT). So managed to drop the sump enough to get my hand into the sump. With lots of rags, once the oil had drained, cleaned it out without dropping the sump fully. Managed to get the magnets out and clean them as well, then sprayed break cleaner in and cleaned out the inside with more rags. Once all clean, bolted it all back up. This can be a bit of a pig as the blots are in hard to get at locations, but just takes a bit of time. Bolted all back up and then re-filled the sump using the fill plug. Once it starts overflowing then install re-fill plug and then go through the gears as AudiPages recommend. Open up the plug again and pour some more in. You can do this straight from the bottles, no marine pump needed. Just push really hard. Once it overfills again then, re-install plug and run through the gears again. Job done, and a few plasters on my namby pamby hands. Take for test run all working sweet. Once the new gearbox oil gets working, gear changes are really, really smooth now. Takes a couple of hours and even getting the parts from the stealer, should cost no more than £40, and a box of plasters. Maybe should have taken the CAT off but that looked a whole world of pain. Hope this helps and will try and put some pics up soon. Auto Box was the 4-Speed ZF CML coded. Cheers Link to comment Share on other sites More sharing options...
Sven Posted October 4, 2004 Report Share Posted October 4, 2004 Glad to hear the oil change was beneficial, but there is a filter on CML as well... (see attachment). Maybe next time eh? You know how it works now... Link to comment Share on other sites More sharing options...
msey Posted October 5, 2004 Author Report Share Posted October 5, 2004 Thanks Sven for the info. See that it is called an Oil Strainer, and thus it was missed. Spoke to the stealers who said that it did not have one. Stupid me and I took them at there word. Ah well. Think that I will do this again, now that I know what I am doing, once I come back from a good round trip from France. This will also give the new oil a chance to act as a wash. Will not do any harm and the price of the parts are cheap, compaired with a new gearbox. Thanks again for the info. Link to comment Share on other sites More sharing options...
Sven Posted October 6, 2004 Report Share Posted October 6, 2004 Yeah, they have a habit of using different names and terms in ETKA and the manual f.i. Very practical... The dealer should have known this though. However, for a proper oilchange it's best to do it more then once anyway... Link to comment Share on other sites More sharing options...
