my 2017 is fine but some of my other cars shifted very hard.My 2008 acadia shifted terrible and some of the old powerglides were very bad shifting so maybe I dont pay any attention to it.By the way I have never had auto transmission replaced in any car i have owned.

What in the world are you talking about when you say, "Adaptive Transmission?" From what you and others say about "them" they are a myth.

Service department had it for a week. They replaced the valve body hoping that would fix it. So far so good. There was another lady who was having the same issue when we were there and that pushed them to go further with the diagnostic and repair. Fingers crossed!

Hi all, yes I'm having the same issue. Slams into (I believe 2nd gear) when accelerating from a low speed. Sounds awful. Took it to the dealership, wasted my time and rental car money and just said since the couldn't reproduce the sound, they couldn't fix it. They said nothing showed up on the codes. It continues to do it at least 2-3 times per week. Not sure what's wrong but I suspect it's something transmission related.

@LilliesVan and @harrisn144 would you mind putting your van info (year, trim, gas/hybrid, etc.) in the signature line of the UserCP (click on red UserCP letters by log out)?

I'm still hoping for a fix for the transmission shifting problem. If anyone gets a solution please post it so I can have a list to take with me when I take the van in the next time. Thanks.

We've been through the NCDS dispute process, and brought up many (not all) of the same transmission problems described in this thread - jerking, slamming, rough shift. Chrysler ultimately said that the transmission, defect ridden as it is, is working as designed. Also they said that the 9-speeds are known for their defects, but that we, as consumers, will come to appreciate that over time. We didn't prevail in our dispute process, but Chrysler's comments in regards to the transmission were just plain stupidity that is just begging to be used against them in court someplace.

My van has the same problem.

I've recently noticed my 2017 Chrysler Pacifica (touring L-Plus Gas FWD) is having a hard clunk/shift after you are accelerating/ let off the gas when you're going OVER 35 mph, then when the van is then decreasing speed, at about 35 mph there is a very hard CLUNK downshift. Passengers in the car all say WHAT WAS THAT! because it's so hard and it seems like something is wrong.


I just PM'd Chrysler to see if they have any suggestions.

Last week the transmission adaptations were reset, cleared, etc. and the 15 mph jolt is gone for now. Last time they did this it lasted for 10,000 miles before it started happening again. They weren't able to reproduce the problem, but since I was able to convince them that resetting the transmission adaptations was an option (and I've been their customer for almost 20 years), they did what I asked.:smile2:

Paper said, "reset trans adaptives, performed trans quick learn, drive learn procedure".

My Pacifica (2017 Gas) also has this problem. It became much more frequent after the recalls. I only have 12000 miles on it.

Hard shifting

Mine has been doing it since 10000 miles now have 36000. Been to the dealer 8 times for this problem along with regular maintenance and they were only able to duplicate it once gave it a update they said it would fix it but it isn’t 50 miles from the dealer and bang shifting problems again. There is no fix for this problem Chrysler knows this that is why we are pushed down the road with a phony software bandaid.

An update isn't the same as clearing or resetting transmission adaptations learning. Until Chrysler can determine a fix for this problem I just plan to have them reset the adaptations when the problem returns. I was called by Chrysler recently regarding this issue and was advised that the dealer should set up a STAR case and call Chrysler support for more help in diagnosing the problem (or ruling out other transmission problems) even if it doesn't present itself for them. If I ever get a better solution, I will post it.

I am also having this problem and have informed the dealer twice about it with no answers. It started after I got a few recall software update done at the dealer. Just like everyone else here, the vehicle hesitates at slow speeds, then hard shift all the sudden and feels like you go rear-ended. I'm at a loss for what to do since it only happens at random an the dealer says they've never heard of the problem and can't recreate the issue. Should I file a NHTSA complaint?

Well I haven't posted in a while. Alas, my wonderful Pacifica started the 1st-2nd gear hard shift/jerk or lurch today. It happened 3x. I'm at around 5k miles. @ScrTchr seems to know the fix with the "transmission adaptations reset." I just PM'd @ChryslerCares with my VIN to see what's up. Hope everyone is well!

Did you try the 'reset' that @SciTchr used?

Hello everyone,
Just signed up to this forum for this exact issue.
I have been reading this thread for a few days and took my 2017 Pacifica in today with 34k miles (bought it certified pre-owned 5k miles ago) to have the oil changed and this dang transmission problem looked at.
Same exact issues here, at very slow speeds (usually in perking lots) it hesitates to shift in the low gears and then SLAMS into gear and everyone in the van freaks out thinking we were just rear ended. Sometimes it doesn't do it, sometimes it does it 3 times a drive!
It also hesitates sometimes when I back out of our driveway on a little hill and when we put it into drive to drive up the hill it literally sits there for a few seconds not shifting at all. Dead in the middle of the road for a few seconds. NONE of this seems safe to me at all and we have been very concerned these past few months.

Of course the dealer can't replicate the problem in their one quick trip around the block so no steps were taken to look into this.
Not sure how to approach this problem, are we still contacting ChryslerCares?

Welcome to the forum. See post 48 of this thread. This is what recently helped my transmission issue.

The other thing to check is whether a TSB for the transmission applies to your 2017 van. @ChryslerCares can look up your VIN and see if it applies to your van. You can send them a private message by clicking on the red @ChryslerCares letters. A TSB is different than a recall so the dealer won't apply a TSB unless a problem on the TSB paper work is present. Take paper work from the forum with you since it is unlikely that the problem will ever show up while the van is at the dealer.

Hello ...
We are having the exact same issue.

I noticed a couple weeks after purchasing used from dealership (2017 ~ 44K miles). I probably would of noticed sooner, but much of that time, it was having some scratches and paint issues fixed.

When this (slip or hesitation) happens it feels like we have been rear-ended! After the rear-ending slam ~ it accelerates very quickly without my foot pressing any harder. Very scary at the time both the jerk and acceleration ... especially, since the reason we had to buy this vehicle was because of a bad accident) :(

Sometimes the jerk is worse than other times. I can go a few day without it happening then it can happen multiple times within a day or two.

Please let me know if anyone figures out a solution to this.

Thank you I will do that!
So far the only reply I got was if they can't replicate it, then oh well!

2017 Pacifica with same transmission issue: sometimes slams hard into second gear at low speed. Very intermittent- no rhyme or reason to the hard shifts. Took to dealer- they said on first visit it needed a transmission control valve- which was back-ordered at the time. Then dealer said Chrysler insisted they try an ECM flash - set back to factory settings- before they would authorize the control valve repair. So ECM flash was done and car was fine for about two months- then started doing the same thing again. Took it back to dealer and explained the issue . They gave us a loaner and kept the car overnight. Next day called and said they checked everything and could not replicate the problem (which I told them they probably wouldnt be able to do) - and therefore nothing could be done. In other words something has to REALLY break before they can get Chrysler to authorize a warranty repair. So we have the car back now (27k miles) and are just waiting for the next time. My wife drives the car 95% of the time and is NOT happy.
