Hi guys I have a 2.0cdti auto, when driving the car sometimes sticks in 5th when it should've gone to 6th. If I switch to manual and shift up it's fine but then if I switch back it will drop back 5th. But as I say it's not all the time. The car has just had a full service too if this helps?

Sounds like the same issue I have. During warm up of the engine mines will shift to 6th at about 90 km/h, but when the engine is warm it will drop out of 6th by just looking at the throttle, but only when the speed is below 120 km/h. At 130 it will stay in 6th. When accelerating to 120 it will remain in 5th when I expected it to shift to 6th. It does this the first +/- 30 km, then it behaves different and stays in 6th much longer, being able to accelerate from 90 to 130 in sixth.
Don't known what causes it, but it's good to hear others have the same issue.

Not sure, I've only made 40.000 km with it yet. In the beginning I've been driving mostly 130 km/h so I didn't noticed, it was until I slowed down a bit I started to notice it. How many miles do you have on yours? Mines has just reached 220.000 km.
I haven't taken it anywhere to have it checked, but I'm thinking of having the transmission flushed in the future. Just have to find a good flusher (and some budget )

Some oddball suggestions to consider.....
Is it possible that the car is trying to regenerate the DPF and therefore trying to keep the revs up?
Next time it does it, check the 'top consumers' menu and see if 'rear window demist' shows, which is the marker for a regen.
Also, is it possible that it's staying in 5th due to higher than normal load on the engine - boot-full of junk, running aircon, demisters, lights, wipers, in-car gadgets?.

DPF filter regeneration did came in mind the first time I noticed, however mine does it twice a day, after my 100km trip to work. I think if it's a regen it is doing it very often. It also only happens when the engine has just warmed up, not the moment I expect a regen. I don't have the top consumers menu, no ecu stuff on my car.
Car load is low, only one person, empty boot, no hills over here. It happens with every weather condition, also when the climate control is off.
The funny thing is, this afternoon it didn't happen got the first time in many many days.

Just a thought,
So I had a enoying wine coming from the engine, which turned out to be the alternator, since it's been changed I've noticed the power steering in nicer/smoother. And the auto box seems to be changing smoother, and seems to change up quicker on lower revs.
Could it be a power issue, how much power does the auto box use.??
It could just be me convincing myself it's different since the alternator bug you never know.

Did you went to a dealer to have it check out already?
I've found a document describing the gearbox as used in an Alfa 159, it does mention some special modes the box can detect, like hill descent and warming up phase, could be it's in one of those special modes?
