My experience with the 09G Transmission...

[CoolAirVw]

600-700 is DIRT CHEAP.

Dealer wants 1200

Hi Desert465,
Bought mine from Reamman Valve Bodies. They do receive your old Valve Body.
Can’t remember the price but it was like $550 for a rebuilt unit and if you send your old they’ll reduce it for like $450.
Give them a Call, I'm sure they can help you out.

All, when you find the 09G acting up, please make sure to reset the adaptive shift program first and foremost. This is the number one solution to complaint, depending on the severity of such. I would hate for anyone to through away $500 to later realize that the computer was causing the shift timing issues. Following this, it may take up to 50 miles of regular driving to allow the TCM to fine tune the shifts and the shift characterisitcs may be worse after the reset, this is normal and they will improve, I promise. Will it solve your shift concerns? Well, that is what we are trying to determine. Following this, you could do pressure tests at the various taps or log the shift points with VCDS, though most folks don't want to or have the time to diagnose the issue to this extent. In that case, the next point is replacement of the VB with a reputable VB vendor. I have only worked with VB Xpress, who would be like the Cadillac of VB's but you are going to pay. As Sphak has mentioned, Ream Man seems to be building significant credibilty in this arena. At this time, these are the only two vendors I would recommend, even over a unit from VW. The latter units may or may not incorporate any upgrades over the defective designs of what you have in your car now. I am unaware of any design changes from the inception of this transmission to those coming of the line today. I would like to think that this is not the case, but there is no literature stating this, except they have changed vendors/design of their unreliable solenoids. The primary failure mode of the VB's is wear at various valve/bore sites, as well as soelnoid issues. This is not a unit where a simple solenoid swap will be a cure-all, like those of previous VW transmissions. Please send me a PM if you have more questions, comments, or info.

Good luck!

My 2007 2.5 Jetta has a hard upshift between 3-4 @ 39-40 mph only when warm. Pretty certain vb needs replaced. Dealer said there are four different vb's for this unit. They gave me part #09G 325 039A but were absolutely useless in which one it was. They said they had to take out the old one for comparison. I found the following pictures but the part numbers are different. Can anyone help which part number I need.[/IMG]

[bjohns86]

This is true, there are four different VB's for the 09G, however for your year there are two. The way to determine which one you have requires you only to open your hood. Look on the top of the transmission back by the firewall and look for a small can-looking part on top of the transmission with two lines going into the top. The can looks ribbed or corrugated. This is your case cooler. If this is not present, you will see a odd looking pad on top of the transmission where this would go if called for. Whether you have this case cooler present determines which VB you have. Most, have this cooler, but it is good to verify this. Again, I would not recommend buying a VB from the dealer. Let me know if you have more questions or are having a tough time finding the case cooler. Good luck!

Hello, Newbie here,

I've been asked to look at a car for a friend. It is an 08 Jetta 2.5 with the 09G. She had it towed (200miles) to a dealer a couple of weeks ago because it clunked when going into gear and wouldn't shift out of 3rd gear. The dealers scan found a 00268 (solenoid valve 6 N93 open/short to ground intermittent) and they claim to have found some pinched wires at the trans wiring connector. To the tune of almost $600, they replaced the connector, erased the codes, and sent her on her trip home. She made it about halfway before the same problem arose.
I have VCDS as I have an 08 Rabbit 2.5. I ran a scan and found that it was coming up with the same code that the dealer got as well as a CAN gateway 001044 (Control module incorrectly coded) .Upon driving the car this morning, it seemed to be shifting just fine. The check engine light was on as well as the PRNDS all lit up. There was no hard shifting as I see described by many other people. I reset the code which shut the engine light off and made the PRNDS normal again and everything seemed okay. I drove the car at highway speed for about 20 miles with no problems. I stopped to check my VCDS, as I had it monitoring a few things, and the code came back up as well as the car going back into 'limp' mode. I tried resetting the codes but it would not shift out of 3rd gear. I got the car back home and let it cool off for a couple of hours wnd now everything seems back to normal.
By the looks of this forum, it looks like a VB replacement may be necessary eventually but being that the car shifts fine otherwise, do you think that I could get away with just replacing the N93 solenoid? The car only has 106000km(60000miles). I think I would change the VB if it were my car but I don't think my friend is prepared to dish out the $$$. Even though I work cheap. lol.

I would re-post this in the DSG category. This is not the 09G.

So there I was, looking for info on throttle body adaption, and this thread came up.
As I've got the 09G box, was fascinated -- although it doesn't take much
And it's readable as well -- which helps

Was a sticky and/or FAQ ever made of this? The info here and background is awesome
Yep, over here VW UK and their dealers are still saying: "It's sealed for life, sir!"
In my youth ran Rover V8s with Borg Warner 35 boxes and it wasn't true then; with the electronic sophistication of today's boxes it certainly isn't true now

Did my fluid change at 2k miles or so ago on my '06 tFSI Estate now at 56k -- got the Blauparts kit to do it with which supplies Meyle ATF VI with Blauparts sticker on the bottle saying meets VW
G 055 025 A2 spec, and apart from a couple of lumpy changes driving back from garage in rush hour traffic, it's been fine in auto, sport, and tip modes

Thanks again for this thread...

[sphak]

Good to hear that this thread is helping others, I would say that pretty much all the credit goes to Brad, he was the one who helped me and others with our issues with the 09G.

I wanted to give you guys a heads up. My transmission is great now, and it’s been without an issue since the VB was replaced. However, doing some research here in vortex, I ended up looking for the Motor Mount (“Dog Bone” Mount) and read really great posts about people amazed with the motor mount sold by HPA and its results.

I bought my dog bone mount a while back and installed it this December. The mount is well made and I’ve bought a few things from HPA before with no regrets but this motor mount is NOT for the 09G.

http://www.hpamotorsport.com/mounts.htm

The first time I tested my car, there was tons of vibration in the chassis. I guess that’s because it’s made from urethane which is stronger than rubber. So I’m now back with the OEM Mount which is cheaper by the way!

So, be aware guys the “Dog Mount” motor mount is not for us, probably it was intended for the DSG.

Today i'm shopping for a used 2007 Passat 2.0T with 90000 miles on it. Ok its not a new car but still, its my hard earned money that i'm willing to spend. After noticing that my seat would not move, the switches and panels in the doors were pealing off... i took it for a testdrive. Everything went smooth no vibration, all good.

Then, a red light, it jumps to green and i step on the accelerator (full throttle), i saw the rev needle jumping up and down, the car could not find a gear. When applied throttle slowly but steady it seemed to be ok, then did the same thing while driving, overtaking somebody, full throttle same thing the car went nuts... did not know what gear to go to? engine going up and down not knowing what to do....

So now my question is, is this a transmission problem? Does the car needs time to adjust its settings to my aggressive driving style?

Let me know because i'm in the market for one of these cars.

Brad, thanks for sharing your knowledge. I have an 03 Audi TT with a 09G transmission giving me harsh shifting between gears. Just spoke to an Audi technician who recommended to perform a "capacitive discharge" to reset the computers to factory by disconnecting the battery terminals and touching them together for aprox 40sec. Do you know of this procedure and do you see any harm on doing this. Thanks.

[bjohns86]

Magarmuch,

The dealer is mis-informed. This technique does not work or at least I have never had it work for me nor have heard of others' success. He is correct in promoting the reset of the adpative shift but the only realistic way to do this is taking it to the dealer (ick!) or getting a VCDS program or finding someone who has one and have them reset it. It is actaully an 'adaptation' of the engine control module, oddly enough. I suspect that you are resetting several controls simultaneously this way. I would also change the transmission fluid and filter, if you haven't done so already. This way you can see what sort of metal contamination is present. being that the unit is 10 yrs old, I wouldn't be surprised if the VB is the cause of your complaints, but I would absolutely cover the simple checks first. Let me know if you have any more questions or need more specific answers. Good luck!

Brad

[magarmuch]

I tried the so called "capacitive discharge" it did nothing, car ran just like before. So I decided to order a rebuilt VB from http://www.reamman.com. I talked to them before ordering, they said no need to reset the computer, just change the VB and it should work fine as long as there is no other fault with the car. So now I wait for the unit to arrive on Friday, if it is not too cold I will attempt to change it out. I also ordered the filter from rockauto.com and found comparable ATF at PepBoys (Royal Purple). I would like to post pictures but don't see at "attach file" any ware.

[bjohns86]

Don't put too much weight in Reamman's suggestion. Anytime the VB is replaced, the adaptive shifts should be reset because even though the internals didn't change the soelnoids and shift valve spring settings may have changed enough to cause issues. The computer adapts more slowly over time then when it is immediately reset. I am not sure about Royal Purple's product line, just make sure it is Dexron VI or specifically notes the VW spec. Good luck!

Brad

[magarmuch]

received the parts (VB, Filter and oil) will try and install tomorrow. Is there some way to upload pictures?

[CoolAirVw]

Here is how to upload pics. Its from a different forum but its basically the same here.

Is it possible to add oil from the top of the transmission? Looks like there is a plug on the top of the transmission with a TORX head.[IMG][/IMG]

[magarmuch]

OK, finally done with the swap out, all smooth now. The trans was almost 100% smooth shifting right from the get go. Did not do any adaptive relearn or reset the computer. It took one short trip of 15 miles with about 5 to 10 stops and the tyranny is smooth as silk. The car has 75K miles, ATF had never need changed, what came out was really dirty and dark.

Made my own oil filler adapter. Very simple cheap and immediately available at your local Home Depot store, pluming section. The thread matches 100%.

Used some rubber washers on the adapter because the thread is too long.



Pump from NAPA, only $8

That thread is 1/4 pipe thread. Actually the thread should be is 10mm x 1.0.

1/4 inch is very close and its fine to use since your fitting is plastic. I've seen guys use 1/4 inch on a aluminum case and damage the threads. 1/4 would be fine to use if you only tighten by hand!

hi all, i've had the car since 08-2008, 49800miles
its happened 3 times throught the years, 3rd this morning on the highway..
each time, it was on the highway, no shifting, just randomly came on, it wasn't flashing or anything, no cel either just inverted selection showing "PRNDS", and was not in emergency mode and stuck 3rd like most i've read

i got to work, turned car off turned back on and it went away.

i have a obdii bluetooth scanner to scan codes when i turned the car back on, and got nothing (should've plugged in when the error was still there)

i did search and most came up on phaeton section of vortex. so far i've read, loose transmission shift magnet to bad valve, and bad temp sensor in dsg trannys...
any help guys?

has the at fluid been changed in the last 50k miles, if not i would start there.

[wushugs]

i have a tranny flush this sat. as a part of 50k maintaince
the issue is that it happens so randomly and seldomly that it might be months before the next time it'll happen

[BMohlman]

Thanks all for starting/maintaining this thread, I bought my daugther a 2006 Jetta 2.5 about a year ago, about 3-4 Months ago she told me it started acting funny. It's at about 91K Miles and said some times when she goes to pull out from a stop (1st to 2nd gear) it appears the tranny slips then engages.(This happens very intermittently) Also, it shifts hard from 2-3 and sometimes 4-5 gear. The dash isn't flashing and my albeit low buck ODBII scanner shows no codes. I am going to start with replacing the fluid/filter, and was looking at the Ross Tech scan/software and interface. Does anyone have experience with the Ross Tech tool? Will it do the adaptive reset on the controller that is discussed here? Also, if I do need to do the VB replacement, how do I tell which VB I need so I don't order the wrong one? Lastly, on tupa's post of the document, it describes getting the radio code how do I know if I need to get the code and where do I find it? Is there a place I can purchase the 09G tranny tech manual?

Many thanks to all who contribute to this thread, I was bummed out thinking I would have to junk the car, or sell a kidney to fix. You have given me a glimmer of hope that it may not be quite as bad!!!

[n2verts]

Looking for some info on the 09G trans valve body for an 05 Beetle. I'm swapping out the valve body and need to know torque values for the 12 perimeter MX6 bolts that hold it in place. Any help would be greatly appreciated.

[bjohns86]

All of the valve body to case bolts should be torqued to 80 in-lbs. Any sensors that may have been removed should be torqued to 62 in-lbs. If you need the location of the various length bolts let me know. You will have 16, 21, and 28 mm long bolts and they all have a special home.

Hello all,
Thank for all those threads and learn us about this common issue.
I bought my jetta from a dealer which is an intermediaire between the owner and I last mid-august.
I didn't fell anything when I tried it for about 10 min. When I came back home from the dealers with the car (1 hour from my spot), I experienced the hard shift. I wrote an email to the dealers to inform him that ther is a problem with the transmission. I brought him the car to check with his mechanic and he told me to let the car for 2 days and the mechanic will work on it. The mechanic changed the TCM, we (dealer and I) paid to the mechanic 1000 dollards but the problem will occur. I brought the car for the second time and now the mechanic told us we have to change the Valve Body. He change it by a refurbished and paid again for 1000 dollars. The problem is not solved and ask now to make a flush of the tranny and change all the fluid.
The car was under warranty extension until 13 august 2012 and unfrotunetely VW america don't want to take it in charge because I called him in march to explain my problem and the warranty expired just before i bought it (currently the car has 87 000 miles).

What tips could you give me to solve this issue ? Can I take a lawyer to ask the dealers to assume that he soldme a car with major pb ?

thanks.

Slim.

Can you elaborate on this point, CoolAirVw? Some MINI's have this same transmission and I have seen their DIYs where they fill via this plug, I believe it's a T55 torx bit. I understand the book method is to fill from the drain hole with a 6262/2 adapter tool, but I don't see why filling from the top wouldn't also work.

I was looking at the bolt on the right. After looking again its the range sensor bolt. I assumed it was a pressure tap.

If the plug "under" the range sensor doesn't have pressure then maybe you could fill there.

Obviously if there is 50-70 psi on a pressure tap then you would have to have higher pressure than that to "push" fluid into it. And dont even try it if there is pressure there.

[sphak]

When I did the valve body change, the transmission was filled from above without any tool. Just a funnel. I’m confused now if that was correct. but it's been running great.

Not by the book, but probably fine. I think VW recommends filling from the pan simply because it increases the chance that the fill level is proper (via the overflow fill tube). That, and it's probably easier. I know in my Jettas, the T55 bolt on top (pictured above) would be quite hard to get to without removing some extra stuff above it.
