RPM FLUCTUATION -So common there's a TSB on it

[seanB7]

I know there's several posts about this. This TSB came out on 2-3-2012. I have this problem on my car and I'll be changing my trans fluid AND FILTER ASAP. Notice how the TSB does't mention changing the filter.






Technical Service Bulletin Transaction No.: 0
32 Shudder or RPM fluctuations while at cruising speed Release date: Feb 3, 2012

Condition

Customer may report shudder or RPM fluctuation while at cruising speed in 4th, 5th, or 6th gear.

Technical Background

Torque convertor clutches may have excess slippage while cruising.

Production Solution

Not applicable.

Service

1.
Check and verify that the software is at the highest level using TSB 2028053, 37 TCM software update for downshift concerns or 2028279, 37 Shift concerns when slowing vehicle. Also, check that the fluid level and condition is clean, full, and matches the required color per the applicable TSB.

Tip: If needed, update the software of the transmission and change the fluid before proceeding with this TSB.

2.
Test drive the vehicle to verify the concern is present.

If the concern can be duplicated, verify there are no fault codes stored for misfires and watch the Measure Value Blocks in the ECM to verify no misfires are seen when the condition is present.

3.
Check MVB 7 from the TCM. Verify Field 3 is reading control and record the slip count from Field 4 while the concern is present. The slippage of the TCC should not exceed 120 RPM in MVB 7 field 4 while the convertor is in control mode. The RPM surge should coincide with TCC slippage. If this reads higher than 120 RPM, the torque convertor should be replaced.

Tip: The TCC slippage will vary when in open TCC mode and should read 0 when in closed TCC mode, this is normal. Replace the convertor for high slippage when the TCC is in control mode (above 120 RPM) or for any slippage when in closed mode (MVB 7 field 4).

Tip: It is not necessary to receive a Repair Authorization to perform this TSB.

Interesting. See my original thread about this (almost a year old, woot!)... http://www.audizine.com/forum/showth...-at-low-speeds

I hope this turns into a recall/extended warranty as im just out of my CPO.

Holy shit this makes me happy. And I agree, being out of CPO myself, if this ever becomes a Recall/Extended Warranty item I'll be ecstatic!

Would this TSB mean I can take my car to the dealer and they would perform this service for free? Or would I still have to pay...

The fact that this is a TSB means its one step closer to being a recall.

Nice I will call my dealer next week when I go on vacation

TSB just means its a known occurance. You'll still pay full price to get it fixed if there's even a fix for it.

If we're lucky, the TSB will eventually become a recall on the TC which is our actual issue.

Hell yes! At least this TSB is the first step by AOA to acknowlege the problem... Now they need to sack up and issue a TC recall.

Same, mine has done this since day 1 of me owning the car as well. It's never gotten any worse, and only happens for the first 5 minutes when cold. But, if I can get it fixed ultimately free, then I will be happy.

Why is this allegedly happening only at cruising speeds in higher gears?

[multiphrenic]

Just noticed this today. Surging between 1800-2000 rpm in 4th gear. Still covered under CPO too...wonder if the TSB has made it through Audi Canada yet.

+1.....

[beantown]

Luckily I had mine replaced under CPO a few weeks ago.

Not sure If it will step-up to a full recall in the foreseeable future, seeing as though the TC and the corresponding labor costs are quite pricey.

[robstitzer]

Looking forward to this becoming a recall ... I'm still CPO so I'm going to bring it up anyways.

Seeing as that you just had this done... What did you say or bring up to get them to replace it?

[Charles.waite]

I think its most noticeable then. You are rarely "Cruising" in 2nd or 3rd gear and since it happens only under really low load (ie cruising) you'll probably never see it unless you are in 4th or higher. I only see it when I've got my foot just barely on the gas, but its getting quite noticeable.

I'm thinking of changing out the trans fluid myself since I've got a Vag-Com to monitor temps and I have no warranty. Couldn't hurt since thats what Audi is now specifying as a "potential fix"..

[Charles.waite]

Read Wildcat333's thread about the topic. THe dealer had to run all sorts of tests and spent a ton of diagnostic time in order to rule out everything BUT the TC. It would be a LOT of money out of pocket without a warranty...

[menace1930]

My car had this same issue and is currently at the dealer. I bought the car used and it came with a 60 day warranty. luckily this happened right away so I am paying nothing out of pocket. My dealer had to run several diagnostic tests and spent some time on the phone with AOA. They replaced the DV and some other hoses to weed out the possibility of a boost leak and now, after 2 weeks of testing, the car is finally supposed to be fixed. They are supposed to be replacing the torque converter and I should hopefully have the car by the end of the week. I will update you guys to let you know how it pans out for me.

Well apart from having a very good rapport with the service manager and being friends with a couple of techs at my dealer, I brought it in due to RPM fluctuations and significant hard up-shifts from 3-4 gear. Apparently, this is caused by the TC not locking-up as it should.

There weren't any codes stored or a CEL, but fortunately they're willing to diagnose any issues that I bring up to them.

At the same time they ended up replacing my intake runner motor (or w/e it's called), pcv, fuel pressure sensor, etc.

[menace1930]

My car seemed to do it much more when it was cold. As it warmed up, the fluctuating seemed to stop.

[wootwoot]

This is scary. I'm at 52k miles, should I go out and get a tranny flush? Is there anything else I can do to keep my TC from failing?

[2007B7cabrio]

^^^ @ Op, nice post, I'll call my dealer today as my flutuations are back again, they where gone with a ne PCV, but now they cam back.... thanks

Have you noticed a difference since being replaced?
Edit: more curious on the transmission software update....

I'm not even sure if they did update the software, however, after the TC replacement, the car has been driving incredibly well...huge difference.

[2007B7cabrio]

OK, so I had my car in for teh TSB yesterday and got it back this morning, I have a CPO so there was no cost to me and here is what they did.

They found fault P23004 and P3137 so the intake flap motor was replaced (V157) - TSB 2016868/8

For the TSB (2028053/1);
They did teh SW updates and confirmed the fluid level, they found fluid level OK, but added "blue/green fluid" not sure what that is, anyway the road test confirmed that the fluctuations are within spec e.g. less than 120rpm, I'll check it tomorrow in cold weather to confirm if it is any better.

Within spec? WTF Audi! The Spec should be 0rpms of fluctuation is normal....

Definitely let us know what the results are. Sounds like they didn't actually flush the fluid as per the TSB, simply topped off the trans.

They did not top off the fluid; they actually checked the level and just confirmed what type of oil was in as the oil type had been changed during the B7 lifetime.

For the fluctuations, it is not cured, they confirmed within spec e.g. less than 120rpm.

I did use VAGCOM and measured the slip, most of the times it was 32-64rpm, but I saw 128rpm slip, so I'll log it and email it to the SA to see what they say , most likely they cannot duplicate it

The tranny oil temp was 23C when started and only 56C when stopped my drive so it newer really warmed up, but I'm in S FL, kind of makes me wonder how it would be acting in northern states and CA where you actually have frost.

How do I find an official copy of this tsb to print it off. Audi just said I need a new transmission, but this is exactly what is happening to my car.

[Dirtyylicous]

I had a shuddering at 1800 rpm to 2300 rpm while accelerating, I replaced a whole bunch of shit and still couldn't figure it out. I took the car to Audi and they told me it was something completely different than what it was.

Took it to an indy shop the following day and they did a tranny software update and changed the fluid (didn't replace the filter though) and the shuddering is completely gone. I urge anyone who has the shudder to change the fluid

[aznaudi]

I have an 2006 A4 with around 88k miles. This RPM fluctuation issue came up about 10 months ago on my car but I was too lazy to do anything about it. Recently found out my neighbor across the street is an Audi mechanic at my local dealer. He took a look at my car and told me it needed a software update and tranny flush. He also showed me the 2 TSB regrading the rpm and hard downshift issue. Nothing new there right? Everyone on here knows about this. Fast forward a few weeks, I dropped my car off at the dealer this morning after taking one of their tech out on a short drive to confirm this issue with him. Got to work and called AoA and log a complaint. Called the dealer back this afternoon and was told that the dealer quotes AoA $3200 for a new TC and $650 for software update plus tranny flush to fix the hard downshift. I will contact AoA tomorrow and try to find out what they will do to remedy this situation.

I will keep you guys posted.

[Rodmar]

keep us posted, this has done this since i owned the car, but didnt care enough to look up anything about it.

[B72011]

The various tranny places that have been discussed on this site have upgraded TC's for like $8-900. Drop the tranny--what 6-7 hrs or less? $4k---NO WAY should you pay this.
