I recently had RRT 17-057 transmission reprogram and 17-043 powertrain flash done on my RWD Giulia Ti. When I am cruising at modest speeds (20-45 mph), regardless of DNA position, the ZF transmission has the engine turning at 1200-1700 rpm. Wen I lightly apply the throttle there is a transmission shudder and hesitation before it kicks to a lower gear or begins lightly accelerating.

I thought the RRTs were supposed to fix this. Anyone else experiencing it still? If so, how have you resolved this?

Thanks,
Emilio

I have this as well, thought i was going crazy, but it happens a lot.....I usually drive in A mode so that is where I noticed it..

This happens to me too. It happens in manual mode as well, however. This leads me to think that its motor related, not the ZF. I have created a case with FCA on this and trying to coordinate a better response with them vs. just software updates.

Are you observing a shuddering or a rumbling? That is, do you just hear a low pitch noise or is the whole vehicle vibrating? In my test drive I noticed a low RPM rumble from the engine, perhaps enhanced by some interior component having a sympathetic vibration (the windows?). If that is what you are experiencing I think it is intrinsic to the design.

Sluggish downshifts are only an issue if you don't get enough acceleration. Keeping the engine at the lowest RPM that can produce the requested power is a fuel saving feature. I did not experience any issues with inappropriate gear selection in my (brief) test drive with the car in A.

Hunting for a gear (repeatedly shifting up and down) is a different issue. Did the RRT resolve that problem?

there have been a few other threads about this. Its jerks the entire car. i.e. you slow down while in a d3 or m3, re-accelerate and the car jolts/skips a bit as its moves. sometimes that acceleration after the jolt isnt very smooth either. I'm convinced (im my mind) that this has nothing to do with the gear box. Seems like others in this scenario have had either their fuel injectors or pump replaced. But ofcourse they were only on this forum to rant about their problems and failed to follow-up with the group regarding any resolutions.

Yes, I know there are other threads on this subject. However they describe different symptoms than what was posted (jerking and mis-shifting versus "shuddering"). Thus, my question directed to the O.P.

I agree that what you have described is most likely an engine problem. There are lots of things that can go wrong to make an engine misbehave that way.

It's the infamous "Cold Start Issue". Had mine back to the dealer for this. They couldn't solve the problem. I heard a fix is in the works.

I'm brand new to the forum - found it and signed up today to see if anyone else was having the same issue I'm having. Well it looks like there are several but I've not seen the cure.

When I slow down and then accelerate I get the jerking - feels like the trans stays in a higher gear and when I speed back up it drops one gear down at a time before if goes to the correct gear.

I'm scheduling an appointment and if it gets fixed I'll respond.

Thanks and seems to a good forum and a good group of people.

Hi Italiano,

What you describe is for all intents and purposes normal in the Giulia. It happens to me and its annoying. There is a update to the gearbox that can alleviate the jerkiness. The update I am sure was issued because x amount of customers have complained. However, keep in mind, the physical component of the transmission itself is playing the larger role. I am thinking the only way AR truly corrects this issue is with a slight variations in the physical design of the transmission on later models.

Hi Italiano,

Welcome to the forum. If you'd like, you can always send us a private message with your VIN and we can also have a case opened for you on our end.

This isn't the cold start issue. It might be related, but this is a completely different drivability issue.
I only get the jerkiness when it's cold then it shifts smoothly.

Saw my first Stelvio in the wild today. I asked the driver if he loved it. Hesitated for a second and said, "It's a little jumpy when I start it but I love it." Sounds like the same condition.

I think this issue is consequence of combination of the characteristics of transmission and engine....this engine has pretty low torque very low in RPM (in comparison with say audi 2.0T), SW does not take this into account properly and trans starts gear hinting for a brief period after revs drop to 1200 or so....it is obvious you can completely avoid it if you are very smooth and that issue does not appear higher in rev range where this engine has great torque...Alfa should address that with SW....my car did this couple of times months ago, but after drivability sw update things are pretty much perfect in every mode.....I also wonder how much time this engine needs to really loosen up....some modern engines become much better, smoother and more efficient after 10k or so (I know I experienced that in all my Audis and BMWs)

Is it possible that there is an oscillation happening like this?

Driver pushes accelerator, does not get the desired response.
Driver pushes harder, suddenly gets more response than desired.
Driver backs off, acceleration drops off more than desired
Repeat

This can be caused by a steeply increasing torque curve, slow engine response to accelerator position changes, and driver that is not used to the above. When the engine is cold the first two items may be worse than when the engine is warmed up.

It can be compounded by very low gearing, which Giulia notably has in 1st (I am pretty sure that if you could disable TC the Q4 could light up all 4 wheels in 1st). The low gearing allows the engine to "jerk" the car in both acceleration and deceleration. Once the car starts jerking it can become impossible to hold the accelerator pedal steady.

If this is the source of the problem, the real solution is to retune the engine to be more responsive (less time lag).

The Esc type hit or jerk/shudder between 1200-1900 rpms at roughly 25-35% throttle is actually a misfire and likely the same issue causing low speed stalls mentioned on other threads. That's all purely speculative and by no means an official.... From what I understand a software flash is in the works to solve the issue in relatively low volume of cars that the previous update did not resolve entirely. I was a little frustrated on rate of progress until our shop foreman/recon manager pointed out that an ecu is like a neuron with millions of receptors that was edited for the US market and finding the specific protocol that is causing the issue/miscommunication out of the millions of reactions per second is a daunting task, at which point I didn't have much response and went back to work, I'm technical/visual so this helped me out quite a bit in maintaining some patience. Also if you aren't in a school zone, neighborhood or traffic 50-60% throttle seems to solve the problem.
