DCT / PowerShift Transmission Update TSB Thread

[Glockboy98]

Hey guys, new to the forum and just picked up a 2012 hatchback about 3 weeks ago. Noticed that in left turns done while coasting about 20 miles an hour, once I start pushing on the gas, about 50% of time the car starts free revving like a manual tranny would in netural. It's kind of freaked me out a bit, because it almost caused me to get rear ended. Anyone else had a similar problem? Car was built 12/11, so it should have any updates preformed on it already. This problem happens in both manual mode and auto.

Ok, I have my car back and everything is working great ! There is no more slipping and shuddering. The worksheet shows there was a problem with the transmission and an oil leakage between transmission and engine. They also redid the TSB 11-12-13.
And my ex-dealer said it is normal!!

That's fantastic news! Keep us up-to-date and (if you can) let us know if it was just the leak or what they replaced, etc.

Did fluid leak into the clutch assembly? I had the same exact issue. They replaced the clutch and did the update. Now the DCT works beautifully 99% of the time. No shuddering.

From the description that sounds like a few of the other cases reported here where the fluid leaked out of the gearbox and damaged the clutch plates. That is a manufacturing defect more than likely, and doesn't seem to be all that common fortunately. It was good that it was detected and fixed properly this time however, unlike the previous and lazy dealer who just said eh its normal.

Thank you all for your comments (PratoN, me2000, suss6052) !

Here is a photo of the worksheet with everything they've done to the car.
Sorry for the low quality (and yes, it is in French), but iPad 2 is really what I had with me to snap a picture of it.


I have an advice to anyone who feels that something is fishy with their transmission : Keep going to the dealer and if one says "It is normal behavior !", well, don't stop there ! Look for another one and get the car to him.

me2000, I don't think the fluid got into the clutch. I checked on the net the different parts, but I am a noob when it comes to engines and it seems to me they were changing bolts and something like this.

P.S. I have one thing to say though : I still hear from time to time the "grinding" noise on my tranny (when changing from 1st to 2nd), but I think it is not a real problem. I can reproduce the grinding noise when pressing very light on the throtle from a full stop. If I press a little bit harder, the grinding noise is not there. If the noise will become too important, I will take it back again. At least, now I know WHERE to get my car to be fixed.

P.P.S. My car idles now at 630-650 as it was before. No more the feeling that the engine is "loaded". And finally, I saw the "mpg" comming up to where they were before, from a 8.9 l/100km (29.4mpg) to a 6.9 l/100km (34.9 mpg) on a short trip on the highway (20 km -vdriving it at a speed of 116 km/h = 72 mph).

Wow, now I know how to say 'transmission' in French! :=)

Im going to go to dealer as soon as I can, its doing the 'dance', :P

Got my car back from the dealer today.

"Test drove car customer car, test drove brand new vehicle for comparison, no problems found."

Guess Im going to another dealer.

I mean, I'd like to think Im just not paranoid. It really does not feel smooth to me, and if I dont apply pressure to the gas pedal perfectly, it usually shifts really roughly/harshly.

But one of their technicians told me thats normal, that if you release pressure from the pedal, it creates an uneven shift, which is what the shudder is.

Thing is, like as soon as I pulled out of the dealership, it shuddered just pushing the gas in, didn't let go of it or anything.

FINALLY got the update for my car. So far (only 10 miles on the update) here is what I can find:

* Seems to shift into reverse much smoother. No more need to tap the gas to get it omove into reverse (after I tapped the gas, it used to jerk backwards and over-rev sometimes).
* Seems to hold 1st gear longer (maybe a bit too long)
* Shifts seem more smoother - not as much clutch noise between/after shifts
* No more "knocking" when I'm creeping forward at a stop light.


WHAT I'M WATCING:
* Clutch noise, to see if it goes away after 200 miles (dealer says it will take the PCM/ECM about 150-200 miles to re-learn its shift strategy and go back to being what most would call "normal" shifting).
* First gear RPM (right now, won't shift to 2nd until about 3500 RPM most of the time, and then quickly shift to 2nd and quickly into 3rd, and then smoothly from there.... again, I'll wait about 200 miles).

Overall, it does seem to perform better.

Now, does anyone have any suggestion for the "relearing" process for the trans? I'm tempted t o drive it a bit harsher than I normally would (ie. forcing it to use the full RPM range of the gear before shifting to the next).

The car is already broken in, it has about 11,000 miles on it, so as for component wear, that's not an issue.

What other people's experiences with this update?

[sirhawkeye]

Small update--the over-rev in 1st gear seems to be gone now. But, I'm concerned with the "rattle" the trans makes after it shifts from 1st to 2nd, and 2nd to 3rd. doesn't always happen... mainly with slow starts from a stop light. Not as apparent with faster starts. Is this normal, though?
