Myself and several others are trying to ascertain how widespread this issue is, and whether it exists in all vehicles and only depends on the sensitivity of the driver (i.e. we're noticing it and it's bothering us, but others aren't even though their vehicles behave the same as ours).
Please choose and option, and relate your experiences, thanks! :thumbsup:
I've been following those threads for weeks now, and I'm honestly a little worried since my SRT is being delivered in 2 weeks. Interested in seeing the results.
Yeah, I have been following them as well.
I really want to place that order on a 2015, but I am afraid of this issue happening. Especially on a 70K daily driver. I would be very upset and very unhappy.
I'm just wanting to try and determine how isolated or prevalent it may be...since I may be in a buyback situation soon I want to know if I'd be stuck with the same problem if I order another one.
I've contacted two other dealerships trying to get a second opinion on mine, but neither one would touch it. They all have tried, but my district manager with whom they've all contacted to talk too about the case would rather me take it to a dealership that has serviced SRT's. Apparently it disqualifies them. My case manager is now going to call my district manager a ask her where to take it. I guess I've been black listed.
What a hot mess.
If this trans was meant to clunk on the 6-5 downshift, how come it doesn't do it when it's cold? Mine is only after it warms up to about 160. At around 200 it's a clunking nightmare.
Sorry for derailing your survey, but I want people to know what they may be stepping in.
Just giving my word of thought I own a 12 and I used to get the 2-3 gear clunk all the time was horrible to try and punch it around 30 and get a horrible clunk then finally go. Wasn't until a couple of months I has notified from here about some updates which included a transmission module update. Needless to say after the update never had the problem again. I know we're talking about two different transmissions but was maybe thinking hopefully it could be as simple as a module or computer update in the near future sorry to hear about the problem guys
My 15 has this issue but since disconnecting the negative terminal several weeks ago, it seems to be better. Happens still occasionally but it's not nearly as prevalent as before. I notice on mine that when it does happen, the trans skips 5 gear and goes from 6th to 4th (watch the dash trans display) which would make sense why the clunk and surge forward. Could this be a simple programming fix?
I am going to go to a local dealer tomorrow that has no less than FIVE Jeep SRT's on the lot...see if I can drive a couple of them and see if there's ones without this issue. Might help my sanity if nothing else.
First started noticing the 6-5 jerk/roughness early on, but it was very mild. Past about 200-250 miles it got more noticeable and I started hearing the clunks. Now it's really bad, even after the new transmission. When it's fully heated up like after a highway drive it'll sometimes jerk and clunk so badly that it's like I got hit by another car I actually have to look really quick to make sure no one did...
No new software for 2015's...several of us hoping for an update soon though. I may be able to find put from the engineers looking at mine today whether there is one in the pipeline.
I'd love a magic software update, but mine just feels like the tolerances are off somewhere in the driveline(too much slop). After the internal parts heat up or the fluid thins out is when mine gets bad. I'm about to start replacing parts on my own. Starting with the transfer case.
I've got a 2014 early build (4/2013) and have had absolutely no issues whatsoever. Smooth as silk. I imagine most of us are having a good experience with this 8 spd. It's a great trans really.
I'm pretty sure my trans is from ZF Germany.. I wonder if these problems started for folks after Chrysler started building the trannys themselves.
My 15 has the 6-5 downshift issue pretty much since day one. Not that bad, but enough that I knew it wasn't normal from the beginning. I have maybe 1800 miles clocked. It bugs me and can't wrap my head around how jeep hasn't recalled these trans and corrected it. Maybe they need to see this thread and do something. Wtf!!!
Will have to bring it in and complain soon. Maybe get the updates.
FYI, When I use paddle shifters it doesn't do it as much, still there, but not as noticeable.

Exactly!! I can't believe that they would let it go like this.
Maybe they're hoping most won't complain? But, for 70K, there should be no major issues.
Engineer tested and drove the car extensively today as well as another locally that was in the shop for the same complaint.
I spoke with him on the phone for about a half hour. Basically the verdict is he believes this is currently a characteristic of the vehicle and present transmission software. He agreed it is poor and not correct, and said that there was a software update in the system scheduled for official release this month after it clears emissions compliance. He suggested I hold out until the software is released to at least see if the behavior improves. I am going to see...still planning on a buyback at this point.
Man, I hope that the new software update does the trick!
That would be great news for all. Then, Chrysler can just put that new update into the brand new builds and not have any issues like this again.
Good luck!
I should have bought the white 14' they had on the lot, but Ohhhh noooo I had to have the newer one because I'm sure all the problems have been worked out by now. Stupid stupid me.

Drove another 2015 today, same crappy downshifts and 6-5 jerk, no clunk I could detect but I only was able to get the tranny up to about 140F in the 20 minutes I drove it.
Your test drive doesn't give me hope, however the software update sounds promising. I just don't understand why the 15's are so much different than the 14's. Most of the 14's seem to be performing fine. Can anybody confirm that the ZF's in the 15's are really made by Chrysler now? My understanding was that the ZF's in the V6's were Chrysler built, but all V8'and ecodiesel's still got the German sourced ZF's.
I have a 14 that was ordered Feb '14 and received April 17. Had the 6-5 clunk since day one pretty much. It is not all the time, but when it does its a 6-5 clunk, and a 5-4 jerk. It's quite embarrassing when to explain when you have people in the Jeep. I love everything about the SRT and plan on keeping it for 10 years so I just live with it and the dealers around here just suck. Just been watching around the forum for a hopeful solution.
