rhollis: It is really frustration when you know someone is treating you like dirt! By everything you have said it sure sounds like you are intitled to some kind of compremise or something. What year is your PAC? Did you buy it new or used and how many miles on it now? Oh if you don't mind saying what state do you live in? If you want to list the selling dealer that might alert others to stay away. Maybe some of us might think of something that might help ya. I know a couple of people who I would be willing to ask to look into the situation if you would like, If so I would need the vin, and anything else. I can only mention it to the couple of people who just might have some input for ya. Hope to hear from ya.
Buy the way what happened with the hearing you had last?
#386 of 838 Rough shift, but no shudder.
Apr 19, 2008 (7:46 am)
My Pac is not an All Wheel Drive. I do not have the shudder that everyone else seems to have, but I do have a very rough shift between second and third gear, even in auto-stick mode. And the clunk I get going into reverse is sure to break another motor mount before not too long. I have tried different driving styles to see if it makes a difference. I find that under hard acceleration, the trans shifts OK. Under light acceleration, that is where I get the hard shift. My trans has been flashed 4 times already. I don't really think a trans flash will fix my problem. I guess I could just floor it every time I take off, but when some other cars are in front of me, it is impossible. And considering the outrageous cost of gas...... It just feels like the car has been set up to tow a heavy load, and it isn't heavy enough-like shifting before you need to. Anyone else with the same problems? Any suggestions? It must be a solvable problem! My PAC has only 13,000 miles and I planned to keep it until the wheels had fallen off!

as a transmission rebuilder ive watched these units since 1989 if one of you guys will help me narrow down some of the causes of these problems ill try and help you figure this problem out. you guys have the cars that have the problems. i have the knowledge and resources at my finger tips 8 hours a day and have a laptop on my toolbox at work. I am not sure if a reflash sets the pinion factor in the trans control module (it should) but in the past few years i have seen hundreds of chysler products thats come into the shop with NO pinion factor set I just need 1 person here who has this complaint to go have your cars pcm checked for one of the most common causes of problamtic shifting in this particular transmission (41TE) A604 If its not set it may cure your problem and if it is set we will have eliminated 1 of the most common reasons for unpredictable shifting quality..just trying to help is all

The 4.0 engine uses a different transmission - I believe it is the 62TE. It a six speed.

thats why i listed the 41TE units specifically the six speeds on the road today are not hitting the aftermarket shops yet and informaion is still a bit slim on the 07/08 stuff chysler also used a 722.6 mercedes benz transmission in the magnums that has a known leaking tranny issue and this trans is way expensive to have built when a simple fix external of the trans can avoid a failure

bulldozer: What you describe is exactally what most of us started out with. The reflash does nothing noticable for most. The reason is the torque converter needs replaced, and the dealer's Service Manager may think because it's a FWD it may not need it. Wrong! There is a problem with the clutches in the TC. When the TC is R&R ed then the newest Reflash should make some big improvement. However the TCM and PCM may take a couple of thousand miles to get things learned and smoothed out. I do not think Borgue Warner (who designed and built these transmissions) had in mind that the engine could be in the 1200to 1800 and stay in any gear, especially 1200 rpm at 65 mph. I think this problem is almost a lugging sorta of thing. I am not techinical, so I am speaking just by my opinion. Tell the dealer that it's the TC and they will know what you mean. It took two full days for mine to be done, and some have waited a bit longer. I sure hope this helps. I too have the Lifetime Powertrain warranty, and the Max Care wrap Service Contract which makes just about everything Lifetime, and I hope I don't have to but another vehicle (we are retired) so maybe. But I need to stay away from the dealers showroom or I might think the latest and greatest would be better. I think my wife would run me over if we got another evhicle. We like our Pac very much, especially the MPG!

My Pacifica has has one reflash and a new torque conver. It still has a continuous minor shudder at fifty five in high gear with the converter locked up. ( about 1200 RPM) It has the 19 inch wheel package. Do you think this might be a pinion adjustment problem? It is AWD

I believe that you are right. Perhaps not just the pinion, but the entire drivetrain seems to have a shudder at a certain pitch (since it goes away under load). I feel that it has something to do with the backlash tolerances throughout the drivetrain and that it is a design fault...

On the Chrysler Forum on another website There has been talk about the pinion coming from the factory not set. I really don't know what that means, but there was a good bit of posting about it.
How many miles ago did you have the TC and reflash done. In march they came out with a more current reflash which I had reflash done on March 31, and there seems to be no noticable shuddering, but I call it more like a lugging, as if the gear was to high for the engine RPM's. But we are very pleased not.
