Solenoid Change 09A Tiptronic

[audi10021075]

Don,
If one of those solenoid is at fault then wouldn't my tranny go into emergency mode?
How do you check those solenoid without vagcom, I only have multimeter.

Thanks again,

[coolvdub]

Dave,
If the Solenoid fails completely or is out of spec to far, then yes it will put you in emergency mode. The multimeter is exactly the tool you need to do the electrical checks. Pull the TCM connector off the TCM under the rain tray and probe the connector per the thread I referenced in your other thread. You don't need a breakout adapter, just match the numbers on the connector with the material I posted. Also if you end up needing to replace another Solenoid. I would try the website that was referenced in this thread if the Solenoids can really be had for $15 each that's a smokin' price.

Don,
How do you disconnect connector from tcm?
I don't want to break anything. There are 4 screws on the face of tcm where black connector is attached, I don't think you have to unscrew these.
Special tools maybe?

[coolvdub]

Hi Dave,
If you look at the sides of the connector you can see on one end it has like a pull tab type of thing that is rounded off so you can get your fingers in there. Pull on it in the direction of the connector lengthwise but away from it, it sometimes helps to use a screwdriver in the gap once you start pulling. Then just pull it until it stops and remove the connector.

I would go take a picture for you but my son has the car right now, unfortunately he rolled his car the night before Christmas Eve, so he needs a car to get back and forth to work until the insurance company looks at his car and totals it.

Let me know if you need anything else.

Don,
Here are the measurement

test cold hot
N88 16.5 21.1
N89 16.5 21.3
N90 16.5 21.1
N91 12.5 16
N92 16.4 21.2
N93 3.2 3.8
N281 62.6 73.1
N282 16.7 21.1
N283 3.4 4.0

I guess these numbers indicate N281 is the one out of spec.
Shoul I go ahead w/ N281 replacement?
Picture is of socket upside down, so #1 would be bottom right, just to making sure I checked right pin #.

Hi Dave,
Well N281 is way out of spec for sure. I can't say for sure it will fix your problem, but it's sure way out of spec. Seeing as this Solenoid controls brake B3 in gears 1-4 and reverse it very well may solve your problem. I'm no expert on these things, just a novice and figure I can test the components and replace them way cheaper than any mechanic. If it was my car I would roll the dice and replace it. The worst thing that can happen is you are no better off then when you started, but you will have at least gained some knowledge.If it fixes the problem you can pat yourself on the back and feel good you saved thousands of dollars that a dealership would have charged to replace the entire tranny. On a side note if you are using the inexpensive Mercon V fluid you can just dump it and replace with little trauma to the bank account. If OEM fluid and it's new just drain it into a clean container and re-use it.

Thanks!

[asparagii]

great thread - thx for your efforts to communicate this Don

[audi10021075]

Don,
After getting solenoid N281 out, I measured the resistance and it was within the spec? I put the new one in anyway, and there was no change.
Did I measured the wrong terminal?
What puzzles me is that when I measured at the terminal end it was high but at the solenoid end it was within the spec!
Any comment from you would be appreciated.

Dave

[herb2k]

Perhaps there is something wrong with the wiring harness - increasing the resistance?

[coolvdub]

What he said ^

[pintail38]

CAN ANYONE TELL ME WHERE THE TRANS FILTER IS ON A O9A TIPTRONIC TRANS.

[pintail38]

DON CAN YOU SEND ME THE THE IFO ON TESTING THE THE SOLENOIDS ON MY O9A TIP THANKS

[pintail38]

I PULLED THE SIDE PAN AND NO FILTER JUST GOT CAR SO I DONT KNOW WHATS UP

[coolvdub]

I will post links to the thread with Solenoid data and also an actual picture of where the filter is Courtesy of Conko who took his 09A apart to fix a reverse problem. The picture of the filter location is in the reverse thread that is in the DIY/FAQ.

Hi coolvdub

I have a 2000 VW Golf 2.0l with 4 speed automatic gearbox. Last week a check engine light came up to my cluster. I put the scanner and I've got P0748 code, so that does mean the failure in N93 solenoid control valve.

I live in Ottawa, Canada since the last week I'm looking for that solenoid. At the VW dealership they want to sell me the valve body, cost $700cnd. Do you know where I can find it?

ValveBodyBuilders has the whole valve body for $500 - They're located in Ontario too. I ordered one from them and it fixed up my 01M transmission's hard shifting problems!

[ginplyr]

I have the shifting problem on my 2001 jetta 01m trans......
I’m getting a check engine light with codes p0730 along with P0740 and the EPC light comes off and on every now and then.

I tested resistance on solenoids and got the following results:
EV-1 N88 70.5 ohms EV-2 N89 75.4 ohms EV-3 N90 140ohms
EV-4 N91 6.4 ohms EV-5 N92 114 ohms EV-6 N93 6.5 ohms
EV-7 N9472 ohms TFT Sensor 34.4 k ohms

all seem to be a little higher then specs. with the exception of the TFT whick is way lower then the specs and 3 & 5 which are way higher. Any advice would be great? What to do?What can be the problems?

[alcord]

Hi everybody

I found at one Transmission shop here in Ottawa a used valve body for $200cnd. The only problem is that the guy doesn't give me any guarantee for it.

is there any problem if I still driving my car stock with the 3rd gear ?

You can't go very fast...

[alcord]

Finally I fix my Volks, I changed the whole valve body plus some other solenoids. My car runs well and you can feel the difference when it shift the gear.

Total cost of reparation $125cnd

[kalelcar]

always i prefer change the complete valve body

[photousa]

How much work, beyond what Don has shown us here is it to remove the valve body? When you say you found a clogged shift solenoid, then swapped them, do you mean you swapped them with new ones? Once you had the valve body off, were you able to replace the internal filter? Thanks

[photousa]

Hi Herb, Did you put the Valvebody in your VW yourself? Do you have a list of any other items that replaced while doing the job? Wiring Harness, ect...Thanks

Yes I did - but I have an 01M 4spd, which is really easy to do (disconnect solenoid harness, remove 13 bolts and the manual linkage and it comes right out). The manual linkage has a plunger rod, a replacement came with my valvebody, but I reckon the old one could've been reused. Aside from that, nothing else was swapped out as I didn't have any damage to my wiring harness.

I was looking at the breakdown someone did of their 09A 5spd - http://forums.vwvortex.com/zerothread?id=4187298 It looks doable, but after spending some time in my friend's engine bay, her car has the 09A and considering the valve body is side mounted on that transmission you might have more trouble changing that one in-car than I did with my 01M.

Hey whats going on guys? after reading this thread it seems like these soloniods Maybe my buddies problem whom I am gathering info for.

Here's his issue at hand:
'03 gti tiptronic. The tiptronic function of the trany does not work at all(Ibelieve he broke it driving aggresively.) 'nor does his dash indicator light(maybe a bulb idk). But, the automatic put it in D and go works properly in all gears..

So could this possibly be the issue, him needing to replace the solonoids? I also dont think he has any CEL's, but i maybe incorrect on that one.

Thanks everyone.

**EDIT: Never mind I just found this thread about the magnets, http://forums.vwvortex.com/zerothread?id=3471001 and that seems to be the issue he has. If anyone would like to confirm this I'd appreciate it.

Hi, I am looking for a 09A transmission solenoid, somebady knows where I can get it? I am in Mexico so right here they are expensives. thank you I will be waitting for an answer

[volksmech1]

nice work guys

[mrianti]

most helpful thread for trans. issues .

I had the no cold shift issue and changed the N92 ,

2 months later it started banging hard on the 2 to 3 & 4 to 5 shift on occasion , then a few other odd shift habits.

I decided then to change all the solenoids ( should have done it in the first place )

totally different beast now .

if one fails the others are soon to follow .

I now have a new N92 if anyone wants to buy !

Hello all,

I need help identifying a part (metal bracket) that appears to go on the post where the wiring harness of the 09a valve body bolts onto?... This metal bracket came out while I was changing the 9 solenoids. I am not sure where/how to put it back. Any help is greatly appreciated. Thanks, Huy

How do I attach the pictures?

Hi All,

I lost some sleep on this one but I finally figured it out. It goes on the solenoid valve N91 post. It sits on top of the solenoid and curves to the right. Don, thanks for paving the way. I followed your blog and was able swap our all 9 solenoid and it fixed my reverse problem (my car has 126K miles). My reverse gear would not engage when the engine is cold. I would have to wait until the engine is at operating temperature 190 degrees before the reverse gear would engage. If your car is having similar symptoms, it could be attributed to faulty N88, N89, and N92 solenoids. If you are going to replace them, I suggest replacing all nine while you're at it. I purchased the solenoid kit from http://cobratransmission.com/index.p...45_947_978_987 for $335 which includes all 9 solenoids and the pan gasket. They claimed to be OEM solenoids and are made in Japan with the correct part number. Remember to TAKE YOUR TIME getting the pan out and replacing the solenoids so you don't damage the wiring. Hope this helps the next person doing this job.

Changed them all 9 solenoids today for a second time but today with a small problem, after I put back the pan and everything else related to taking off the valvebody pan, I scanned the car and to my horror got a code that says" 00258 solenoid valve (N88) short to ground.
and I know there is a black wire that came out of N93 that I put on N88 bolt, can anyone guide me to where that ground wire has to be bolted? I lost its location in the process of taking the valve body out..
Thanks in advance.

Hi,

The black wire from the N93 goes on the N91 mounting post.

Thanks to Don and his post, I just finished replacing all 9 solenoids in our Jetta with 09a trans.
The transmission is back to normal.

The issue was engine rpm spinning towards the redline during accelleration.
Only code showing was "00300 - Transmission Fluid Temp. Sensor". Dealer and repair shops say new transmission
is needed. After reading vwvortex forums, decided to do solenoid replacement instead.

A few notes from the process,

- I used compressed air and a stiff brush to clean the area around the transmission before opening it.

- Like Don, I used a ratcheting tie down to pull the transmission rearward. I hooked onto the skidplate
rather than the CV. Other end hooked to rear cross member.

- The pan was easier to remove if I lie on the ground and put my whole hand into it and used my palm to push
it towards the front for clearance. My helper wiggled and pushed on the wiring looms from above. I tried
to keep the vent tube away from the valve body to avoid damage to wires.

- With the pan was off, the red tamperproof seal and refill plug are easily tampered with. Note that
the fill spout has a metal collar which will resist prying up on plug.

- replaced the 9 solenoids - do-able but not easy because of limited access.

- I assumed that weight of transmssion fluid is fairly constant regardless of temperature,manufacture
or length of service. Since there was no fluid leak, I wanted to refill with the same amount of fluid
drained. To accomplish this, I used a digital scale to weight the drained fluid. Be sure to weigh
the empty drain pan first in order to figure out the net weight. Refilling was easy. Weigh the
bottle(s) before adding then weigh them again after. The amount added is the difference between
the 2 weights. BTW I refilled with Mobil 1 Multivehicle fluid.

I needed the following in addition to regular hand tools.

- 1 jack stand (I used the factory jack to lift the vehicle)
- 1 ratcheting tiedown strap
- air compressor with blow attachment
- digital scale with at least 10 lb (5 kg) capacity
- 1 cooperative female helper during pan removal/installation.

I am greatful for the info gleened from this forum.

Thanks,
Doug
after dog bone unbolted, trans can be pulled back


pry on outer edge (plastic part) to avoid prying on metal collar.


I used digital scale to determine refill amount.
