Just wanted to give a bit of info on changing the ATF on a 09A 5 speed tiptronic transmission. The 09A is different from the 01M, in that there is no longer any separation of the final drive and the transmission. All parts now share the same fluid, you no long have to buy gear oil for the final drive. The following is not a step by step, but just some information to go along with the Bentley procedure.
If you are looking for the filler plug, here are some shots. The drain plug is the big one on the bottom. I think it’s a 15/16, I didn’t have a metric that size. I would guess 24mm? Too lazy to convert.
Unlike the 01M 4 speed automatic, it seems that it is not easily possible to change the oil screen (filter). The Bentley manual does not give any mention to the filter whatsover. The design of the 09A places the valve bodies at the front of the transmission, rather than underneath like the 01M. The 01M filter is easily accessible from the underside of the transmission, by removing the pan. The 09A, however, does not have the filter with the valve bodies, and I am actually not sure of the exact location. Judging from the parts display screen at a VW dealer, the filter is roughly behind the torque converter inside the casing. I had already purchased the filter, and then realized that changing it was hopeless unless I removed the trans. Now I could be wrong about all of this, but this is my take on it. Below are some pics of the filter, in case people are curious. It is apparently a fine metal mesh that is used to filter.
Ok, on to the fluid change. According to the Bentley manual, there is a procedure, which calls for draining the fluid, dumping in approx 2.5l, and then checking the fluid level at a specified temperature (By the way measuring block 002 is used for the 09A trans temperature). BE SURE TO GET THE RIGHT FLUID. Most part shops will try to give you the fluid for the 01M trans, so be sure to get G052990A2 for the tiptronic trans. It looks like traditional trans fluid (cherry cough syrup) in color. Oh and a funnel like something below will do the trick.
Having performed the procedure as close to the manual as possible, I can tell you that THIS DID NOT WORK FOR ME. I managed to drain the fluid without jacking up the car, which was nice. I used a 7.5 Qt pan, and the drained fluid filled up a good amount of the pan. I unfortunately did not measure exactly, but it appears that roughly 3.5l was drained from the trans. So, when going to fill up the transmission, I decided to pour in 3l. Did that, got the trans up to temp, and pulled the check plug. Quite a bit of fluid drained out, I would guess somewhere around .5l (surprise). So anyway I sealed the trans up and took her for a drive. I HIGHLY RECOMMEND YOU DO NOT DO THIS. The trans shifted ok, but it sounded like the differential did not have quite enough oil. Here's a poor shot of the old oil below. It looked kinda like chocolate syrup. The drainplug (magnetic) actually did not have a whole lot of metal on it. Changing at 30k, some of them chipped, with a few 1hr drives at 100+ did not seem to screw up the fluid that bad. It looks like 40k would have been ok for me, but I don’t have any actual oil analysis to back that up, so my comments really don’t mean sh*t.
I drove about .5 mile like this. Hopefully nothing broke. So, I quickly went back and dumped in another liter. This seemed to do the trick, getting rid of all the horrible noises and such. I added a little more after this, just to top it off, after all, more is better than less. What could it hurt, eh?
oh ok nevermind. Anyway, it looks like roughly 3.5l - 4l should be used. I cannot be certain, so I would recommend simply measuring how much fluid comes out and replace that (very technical). Well of course only do this if your trans has not been leaking fluid profusely. So, for those who are going to do this, I would recommend replacing the red sealing cap, because it would likely break when you try to remove it. If you are slick, then go ahead and save it. But most likely it will be a little delicate from the heat. So, I would say, get the cap for sure and also the drain plug washer. The black plug should be ok, and simply pull off. It might be a little stuck. If you really want to do the fluid procedure, you should get the check plug with washer too (I don’t see the point of this). The part numbers are listed below.
G052990A2 Tiptronic Trans Fluid
N90414201 Trans fluid level check plug
09A325429 Trans Filter (good luck changing it)
001409069D Drain plug washer
01M321435B Red trans filler cap
01M321432A Back trans filler plug
So, to recap, I used about 3.5-4l of fluid (actually I personally used about 4.2l). If anyone decides to change the fluid, post how much exactly you get out, I am curious. According to a technical paper on http://erwin.volkswagen.de, the fluid change is approx 5l, and the trans fits about 2.5l using the fluid check access, and I actually drained out about 3.5l . So.. there are some conflicting numbers there. Below is a pic from the screen of the technical paper. The actual document is sealed media, which won't let you copy or even do a screenshot of.
Finally, I would recommend going to Auburn VW http://www.1stvwparts.com/ for buying the parts. They sell at 20% over cost, which is cheaper than IMPEX (http://www.vwparts.com). Not all parts can be looked up on the 1stvwparts site, but if you put the parts numbers you need in the comments section, they will help you out. You can always call them too. For example, list price on the trans fluid is somewhere around $30, IMPEX is $25, and 1stvwparts is 20.74.
Oh and btw, don’t forget to use the VAG tool to initiate basic settings with the transmission and throttle for smooth shifting. It really does make a big difference, especially if you have cleared any codes or made any changes.
If you’re bored, go to my friends site, btw. He is an attention wh*re and loves new hits. He is also hosting my pics for me.
