Thanks Steve :o)
If I can be a bit tongue in cheek, I think VW's "Sealed for life" statement is pretty accurate. I translate it as saying summat like, "Your box will go a knacker early on because you can't service it."

Yes, that is my plan still, after the repair work, although i will be shortening the intervals now to around 40-50K km. And it is still better than VW's "sealed for life" rubbish

Thank you very much Steve.
So, the level tube lets about half the oil out. My box was replaced short while ago. I doubt the car will get to the mileage that requires the filter changing in my ownership. Replacing half the oil each year seems reasonably easy bit of conscience banking. Or whatever you wish to call it. What do you reckon please? |

how much oil came out after i took the drain level tube out? about 3.5L before? not much, can't remember.It was a while ago The auto holds around 7 litres. On a drain and refill as above you will only remove about half the oil.Thus the 3.5L collected.The rest stays in the torque converter/pump It is quite simple to check the level. With the engine running, and gearbox up to temp, and the vehicle on level ground, you remove the gearbox sump plug.Because of the inner drain tube, nothing or almost nothing should drip out, if the level is correct. I don't advise doing a cold drain and refill, guessing the amount to replace, but it is up to you. If you simply replace what comes out, should be ok (providing the level is correct to begin with). I would also strongly advise changing the internal filter, especially if you have a few miles on.They do block up, which can cause big problems. Edited by Rebuild - 30 Dec 19 at 14:00 |

Thank you Steve. Have you included the oil that came out before you took the "Drain Level Tube" out in the 3.5L please? If so please would you guestimate how much oil came out after you took the drain level tube out please? Or, if you prefer, how much came out before you took the drain level tube out please? I'm thinking about simply draining via the drain level tube, and then topping up again. After all, half a loaf is better than no loaf.

Fantastic account Alonline, thank you very much :o)
You wrote: - Lightly cracked the gearbox drain,5mm key.Unscrewed fully.Oil poured out quite significantly for a bit, was not expecting this as i thought it would only weep.Gearbox must have been overfilled from factory.Also angle i had vehicle at should also have ensured no draining either. Waited till oil only weeping.Turned engine off.Drain level tube up inside the sump drain can be removed with 5mm allen key.The tube is only plastic, so make sure the key is seated fully. Drain the rest of the oil How much oil did you get out when you "Drain the rest of the oil " please? |

Another great post Rebuild. Since we have now lost the separate modifications board (due to the fact that it's been like a graveyard around here for the last few years) I'm keen to put all of the how to do's and fixes in one findable place. I am gradually collecting all of the links to those threads but there are 350 + other threads to look through to find them. I need to check that all the links work and are in some kind of order. There are some good threads written by others but it is looking embarrassingly like the the Rebuild & T5 TDI show so far. I don't really care as long as we preserve all the work that has been done so far. It won't be up for a while but I will try and get it made a sticky as Greg has suggested.
I don't think anything is lost (apart from pictures that have been photobucketed) it's just question of some organising. I'm quite enjoying reading the old stuff dating back a decade or more. Anyway, if you (or anyone else) has words/pic for any jobs that you have done but not posted about, post 'em up and we can build up our manual.

Gearbox is fixed.
K1 clutch clearances over spec and seals damaged, causing the thumping. Anyway, all fixed.Dave at Automatics of Marion (Adelaide) did his various modifications that he does for these, and some other stuff (K1 piston and friction fibres replaced, new more reliable small can solenoids, air cooler). Refilled with my choice of Penrite ATF FS. All up $3500 AUish. |

Have been having problems of the auto thumping into Drive, on first selection, the last 1500km or so, so have done another partial oil change and filter. At 160K now, so only 23K since last. Details here, Oil didn't look real flash when inspected, and the sump pan had some rubber type soft particles. First pic, removed oil on left, new on right Gearbox may be going in shortly for full dismantle and rebuild

Hi, I changed the trans. oil (to Penrite) as suggested on this thread and had a couple of months of trouble-free motoring, then the auto started playing up with poor (mushed) upward gear changes and bad baulking as it selected the lower gears coming to a halt. I changed the oil again and found small particles of metal on the filter, reset the transmission memory but the problem got no better.
Having found the only Auto Transmission repair shop in Victoria to look at the problems I took it for a computer analysis which interestingly presented no active transmission fault codes. However I was advised last july that the transmission was destroying itself and I was presented with a full $6400 rebuild!!! Given that the van is worth squat with a stuffed 'box, I booked it in. Now, I have no allegiance to this organisation but was extremely happy with the service I received. The Manager, Sid Quintal has a lot of experience with these boxes and although he doesn't do too many these days he has done quite a few in the past!!! The van was dropped off on Monday and I picked it up Thursday lunch time. The following work was done; New Gaskets, Seals, Rings And Oil Seals New Friction Plates New Band New Oil Filter New Bushings New Bearings New Servo Piston Assembly New Aftermarket Forward & Direct Clutch Drum New Electrical Solenoid Block Transgo Correction Kit Remanufactured Quality Torque Converter New OEM Gaskets, Seals, Rings And Oil Seals New Friction Plates New Oil Filter New OEM Updated Wave Ring New OEM Oil Pump Half Assembly New OEM Solenoids Remanufactured Quality Torque Converter Dyno Tested To Ensure Smooth Operation After all the preliminary tests are carried out and
accepted, our transmissions are all built in an environmentally controlled area
where we ensure the best rebuilding practises are followed and our quality
control is strictly adhered to. When the rebuild process is completed, all our
transmissions are dyno & leak tested prior to shipping or installation and
fluid filled to allow for a cooler flow check to be performed in the vehicle. 2 Year/50,000km warranty (Non Commercial Vehicles) applies to our fully rebuilt transmission and torque-converter assemblies which have all been through testing for Valve-Body/Mechatronic operation, component leak down, clearance and specification check, before being assembled. Once assembled, they are then dyno tested prior to shipping or fitting. For those of you interested this is where I went Sid Quintal Service Manager A&B Automotive Remanufacturing 12-14 Cahill Street, Dandenong South Victoria. 3175 Ph: 03 9768 3755 Fax: 03 9768 3543 E-Mail: sid@abautomatics.com.au I had a quick tour of the workshop facility which is impressive and spotless. Interesting to see the number of prestige cars there that have endemic auto box issues that A&B repair, they have the only Australian licence to repair ZF boxes. I hope this helps. |

Andy, in future don't quote the orig post, it's unnecessary. I'm not familiar with later models. The gearbox can also be filled through the drain hole in the sump with a suitable fitting as referenced above by Ozevo Edited by Rebuild - 12 May 16 at 11:40 |

Whilst this is an old post it reminds me of how bad a design this auto was . how could VW have expected the fluid to remain pristine inside the sealed box . When our auto failed because VW dealers would not do the service at 60000 kilometres we found the fluid was BLACK the sludge in the sump pan was so thick I wrote my initials in it then the filter was completely blocked with debris etc . This had caused ours to self detonate bloody expensive to rebuild , all because those idiots at VW seemed to think the fluid would last . They sold the auto as a "Sealed for Life "but they would never disclose what was "Life " . Then they had the gall to release the DSG and then let everyone know that they SHOULD be serviced at 60000 and guess where the filter is in a DSG yep OUTSIDE the box hmm I smell a rat . |

I do the Porsche like Ed China, laser thermometer, as long as it is warm the fluid will flow easily.
Maybe I am doing it all wrong but on them it works?

is the level tube located inside the drain plug? Yes
How do I check my atf level? I think i explained it well enough above(did you even read it?), but here it is again. - engine running, vehicle on level ground - gearbox oil at approx 30-40C.To do it properly you need VAG software to read oil temp - remove gearbox sump plug - oil should only drip out, if at all. - if low, fill as above main text, or an adapter to sump plug as per Ozevo - if high, let it drain. - refit sump plug Edited by Rebuild - 04 Feb 15 at 11:19 |

Very similar to doing the Porsche auto boxes. There oil goes black/dark red and lumpy and blocks the filter with what looks like half set jelly.
I drain the box, refill, run it for about a week and then change again, you get allot of crap out with new fluid. New filter and new fluid and then all is well. Makes a big difference to the box when done. VW like porsche said never change it, I do them around 70K as the fluid appears to go off. The filter I had was mesh on top but more a paper element lower down. Good write up!

Thanks for the prompt reply, Rebuild!
I will leave the motor under-shield off and run the van for a week or so and then check again. What with spillages (me being clumsy) I used all the 4 litres in the Penrite DX-VI pack. I assume its available in 1 litre packs for top ups. HNY to all!
