After dinner we hopped into the van and proceeded to leave. When I put the van in drive, it took aprox 3 seconds, before it dropped or clunked heavy into gear. I put it back in park and when I did the process again, the clunk was there.I called dealer and they say it's because it's to new < bullshitzu <that's what I said. Bill

I have an 06 SXT with the 3.3 engine....I have had no transmission "problems", but I am amazed that the personality traits of the this tranny hasn't changed since my parent's 91 Dodge Dynasty (3.3) and 94 T&C van (3.8). The tranny in my 06 still has that stumbling feeling shifting from 1-2 and has what I call a "long-duration shift" as it shifts into 1st when approaching a stop. It also has a slight whirring/flapping noise when coasting at 10-20mph. If I hadn't had previous experiences with this, I'd be concerned. But both of my parents vehicles did this from day 1 and lasted 90k miles before having any trans problems. My dad did zero maintenance on the transmissions on those cars, and both began to slip right around 90k. I think most of us can assume reliable service for up to 100k these days, but if you're looking to drive yours over that, then I would do regular fluid changes, upgrade the trans cooler, and drive it as easy as possible.....these trannys don't take abuse very well.

Replying to: twocycle2 (May 06, 2007 5:01 am) Please be aware that the transmissions that were in the Dynasty and the 1994 T&C REQUIRED a pan drop/filter replacement/fluid top-off with ATF+3 transmission fluid every 30,000 miles. That the transmissions in those cars didn't fail until the 90,000 mile mark is actually a bit surprising, I would have expected them to fail much sooner.   The transmission in your 2006 Grand Caravan uses a fully synthetic ATF+4 transmission fluid, and per your Owner's Manual, you don't need to replace the fluid ever (assuming you aren't towing or driving in a high dust environment). That said, some folks still adhere to the 30,000 mile schedule of the earlier vans, others drop the pan and such every 100,000 miles on the Gen4 vans.   Best Regards, Shipo Replies to this message: twocycle2 (May 06, 2007 10:54 am) shipo (May 07, 2007 3:11 am) playtime (May 07, 2007 6:57 pm) and 1 more...

I don't remember what the manual for the Dynasty said, but I do know the T&C said that no maintenance was required for "normal" service duty. That struck me as odd back then, given the problematic history of these units, and that was even back when Chrysler offered the 7/70 warranty on the powertrain.   Question for you....do you know specifically what the problems were with those early units that caused the early failures (I apologize if this has been asked previously in this forum, as I have not gone back and read every page). I heard of people in the early 90's who barely got 1k miles before it failed.   thx for the info Twocycle2 Replies to this message: shipo (May 07, 2007 3:11 am) playtime (May 07, 2007 6:57 pm) shipo (May 08, 2007 2:27 am)

Replying to: twocycle2 (May 06, 2007 10:54 am) As I understand it, there were a few software problems when the 41TE first came out, however, those were corrected within the first year or so. Under the same proviso "as I understand it", the vast majority of problems with these transmissions was due to the introduction of incorrect fluid. Folks would take their van to Jiffy Boob or where ever and wind up with a Dextron based transmission fluid in their tranny. These early 41TEs required ATF+3 transmission fluid (which was a semi-synthetic fluid), and as such, it has a different coefficient of friction. By introducing Dextron into the mix meant that the clutches wouldn't grip the way the computer was expecting them to grip, so the computer would cycle the clutch trying to get it to lock up properly. Unfortunately it would do that again and again and again, several times per second, until the transmission failed shortly thereafter.   Best Regards, Shipo Replies to this message: playtime (May 07, 2007 6:57 pm) shipo (May 08, 2007 2:27 am)

Replying to: shipo (May 07, 2007 3:11 am) I have heard or been told the same as you about the fuild "but" I have been told and it does state in the owners manual "use only Chrysler approved or Chrysler transmission fuild only" and if you do not adhere to this statement in the owners manual you can be expected to pay for a new transmission. I know when a transmission is taken apart from looking at them myself what type of fuild has been used whether synthetic or regular fluid. There are reasons for using the man made trans fuild and that is in the winter time your fuild starts circulating almost instantly and with the old based fuild it takes time for it to warm up and same as an engine you end up with metal on metal surfaces touching along with a pump that runs empty for a few seconds and in some cases that just enough time to do damage to a transmission. Just like my 2005 T&C when I purchased it I asked about using a synthetic type of oil and was told it would be a waste of my money only to have Chrysler 3 months later advise all of its dealers to start using at least a semi-synthethic engine oil. At that time they stated it was to help with fuel milage only to later find out its because Chrysler has such a high problem of sludge in their engines mostly the 2.7 v-6 but that is another complete story for another place. Also I have heard that Chrysler had received some bad programed computor chips for some of their vehicals causing all types of problems but they were not the only company using the same type of chip with programed problems them being programed wrong.

I guess it isn't at all surprising that there are still transmissions out there failing due to the incorrect fluid. Annoying.   As for why to use it the synthetic ATF+4, I don't believe that winter has anything to do with it. Automatic transmissions get HOT due to the constant shearing going on inside (primarily in the torque converter), and synthetic tranny fluid deals with the heat WAY better than semi-synthetic or conventional ATF. Oh, that an as of the 2000 model year virtually all Chrysler automatic transmissions were designed and built specifically for that fluid and its very specific coefficient of friction.   Regarding synthetic engine oil, well, I'm one of those that never bought the company line anyway. I converted our 1998 DGC Sport 3.8 to Mobil 1 (currently using 0W-40) at the second oil change, and I switched our 2003 DGC ES 3.8 over at the first. Warranty or no, I then went to 10,000 mile OCIs (supported by UOAs of course), and now, with a combined 230,000 miles on the two vans, their engines are as robust and spotlessly clean (on the inside anyway) as they were the day they left the factory.   Best Regards, Shipo
#1337 of 1833 2002 and having prob w/ trans... any suggestions? by rasilla24 May 08, 2007 (11:46 am)
We just bought this car (used w/ 26k miles - the smaller engine version) and as we drove it off the lot experienced transmission problems. Thankfully, the dealership has agreed to "find and correct" the problem. However, they have tried 2 times with no results. It is back in the shop (for a third try) and I was wondering if any of you have experienced similar problems and if you could help give a diagnosis. Our desperation for a working car is growing fast as I am expecting our second child in the next 6 weeks. Please help   Problem: It refuses to change gears (seems stuck in second) when accelerating/decelerating (most commonly in highway entrance ramps, but has also happened leaving the grocery store). When this happens all of the gear indicator lights have those boxes around them. This is sporadic - we did not notice it during the test drive when we purchased it.   The dealership has replaced "electrical control modules" - to no avail. Any ideas?

Replying to: rasilla24 (May 08, 2007 12:24 pm) Hmmm, electronic gremlins. Yuck!   One of the problems with electronic problems (especially with a used car) is that you almost never know going in where the problem might lay. Was the van in an accident? Did the previous owner mess something up trying to add a modification? Is there a bad wiring harness? Is the Transmission Control Module (TCM) somehow hammered (apparently not as it is an odds-on bet that that was the first thing your dealer replaced)? Is the power supply to the TCM clean? Are all of the sensors inside the transmission, and the sensors that report on engine operation, throttle position, vehicle speed, gear selection and a whole host of other conditions, reporting the proper metrics?   At this point, were I in your shoes I'd be losing confidence quite quickly in your dealer and be looking to reverse the transaction. Said another way, it's time to start asking for your money back, possibly with the help of a lawyer.   Best Regards, Shipo
