HI every one seems that we all are having the same problem with the shutter transmission,I just got my 07 spring special edition Pacifica and felt the problem when it was 300 miles, I took it to the service and they told me that the TC needed re program,the problem still there, also the front end is noisy, please let me know how do you guys got your fixed.
I don't know what Chrysler is doing about this seems to be a very usual problem.

Hate to be the bearer of bad news but I as well as many others have yet to get our Pacifica repaired, we are in the middle of a buy back. Our front end was also noisy to the point that it sounded like it had bad struts on the front but they still could not diagnose it, the shuttering is a bad TC and is a bad design which came straight from my service rep. He said that they were developing a new one to correct this but it still has not happened, I quit worrying about it once we started working on a buy back.

rea4: I had a real clunk when at a stand still when I put into D or R the transmission made a loud clunk. The shifting was not firm but a sloppy shift. When I went in for the 3,000 mile oil change the tec. found a TSB and reprogramed transmission. That changed it and the issues were gone.
   We had the same issue at 30 to 40 mph as you describe. I wondered if the engine was needing the 89 octane as the book suggests. We had filled up the tank at a funky Shell station, and I wondered if they had 10% alcohol and our mpg went down to 21.4 where we usually get 24 + mpg. So I went to our usual Conoco station and put the 87 octane. The problem went away.
   Perhaps your dealer did not know about the TSB? Maybe the gas is 10% alcohol? You might consider taking it to another dealer. Hope this offers some directions to consider.

Replaced the torque converter in my '07 Pacifica Signature Model at 3,000 and the shudder problem is gone. I now have 7,500 miles and no repeat of the problem.

I bought a 2007 Pacifica AWD Spring Special... within the first 700 miles we noticed the shudder. Got the salesman involved and he walked me to the service center. They claim they were not able to duplicate the problem. Took it back again and same result (unable to duplicate problem).

How do you get them to acknowledge the problem? Did the buyback process start with the call to Chrysler?
---
Also, we are experiencing a strange problem with the electrical system. The HVAC shuts down every now and then for a minute or two... the lights go out, the fan stops, and the radio goes mute. One hot Saturday, after I put the kids in this happened... and I noticed that 3 of the four windows would not role down as well. Weird... Took it back recently and asked them to reset the clocks which over the last month have become off by several hours!

I would print off this whole thread and take it to them, they tried that with me on the first two trips to the dealership. I finally took it to them and told the guy to drive the damn thing home, to get groceries and for a week if he had to but I wanted it fixed! They had it for ONE day and called me and said that they felt it and it was the torque converter, 704-825-4544 is the service dept of my dealer, call them and talk to them and ask them what documented problems they are having. The service guy told me he drove 3 new ones on the lot and all did it, if you need his name let me know and I will get it for you.

They installed the latest driver for the trans computer and the shudder at 30 miles it's gone but still very smooth (the shudder) at 45 and 70 mph, also when I brake the downshift is very harsh and intrusive any one of you have feel the same?
I have told them to just change the TC, I want to keep the car.

When you refer to a "shudder" is it kind of shaking feeling? I feel this at 25 to 28 mph. We had a TSB done about 2 weeks ago because when going into gears from park had a thud sound. From that point we have had the thing at 25 to 28 mph. We also have noticed (maybe due to the colder temps) our fuel mpg has dropped about 2 mpg.
  I am sure this might not show up at the dealers test ride. So I am waiting for it to either get worse or maybe I can duplicate the problem sometime for the service manager.

yes is like a hesitation with some vibration, the clunk noise when you move thru the gears is solved with the newest software on your TC, but the shudder is from the torq converter

Thanks for the advice. Finally, the dealership found the TSB and said they would order a new Torque Converter. They also stated it is likely that the electronic shutdown was related(?). Oh well, I really appreciate everyone's input... without it I may have had to accept it as 'Normal'.
 
While it is NOT NORMAL, it doea (unfortunately) appear to be common.
