That, and are the current units coming off the line having the same issues. If not, them why are we not seeing the updates sent to the dealers to address those of us who were the early adopters that have been the test bed to report all of these issues. Seems like some state lemon laws may be testes to the max soon

Re: I Think I Fixed My Rough Shifting 8sp Transmission

I have 2 2014 JGC Limiteds. These are my first Jeeps I ever purchased. The first, with a build date of 4/13, exhibited the rough shifting. I haven't gotten any of the thumps or thuds that people have discussed, but rough shifting nontheless. The battery cable pull definitely improved things and then the most recent flashed improved things even further. It made driving in ECO mode acceptable and other than a slightly noticeable downshift from 4 to 3, overall pretty darn good.

Well, now that I just got my 2nd one 2 weeks ago with a build date of 8/13, I will tell you there is still a very noticeable difference between the two. The new one I feel absolutely no up or down shifting roughness. This is the way a vehicle should run! Now there is only about 450 miles on the vehicle so far - so we'll see how things go. So, if we take the "learning" part out of the equation for a moment, based on driving both vehicles, there has to be something more that changed other than the software flash. It drives like two different vehicles - they are identical. I'm wondering if they determined there was another part that needed to be tweaked or replaced, but they aren't making it known yet.

What's also interesting is that they changed the tires as well. When I went to check the air levels, my new vehicle recommends 36 psi in each tire, but my original recommends 33. I then compared the tires and the new vehicle has the same Michelen Latitudes, but they are marked "Green" and the treadwear is 600 instead of the 720 in the originals. I don't think this probably has anything to do the with tranny, but I bet you it has to do with the vibration issues at highway speeds. My first Jeep has issues with that as well as others that the dealer told me about.

In any case - a key lesson, is WAIT until a new model year has 6 months of deliveries before purchasing. My second Jeep has been just about PERFECT since delivery (only issue is I can't sync the Key Fob with the seat/window memory - which is likely a 8.4N flash issue). It really is like purchasing two different vehicles.

Re: I Think I Fixed My Rough Shifting 8sp Transmission

Well...about 3 weeks after the latest reflash from Chrysler and the tranny went back to shifting like it used to. Rough downshifts into the lower gears, especially while in stop n' go traffic...ECO mode or not. It now sticks in first after a cold start, and over revs...hunting for a gear.

I'm actually going to try my battery disconnect trick again to see if things improve.

I'll keep everyone posted...fingers crossed!

Sorry to say but this is true of just about ANY manufacturer... a way to see this is to trend the reliability ratings with the number of new vehicles released in a given year. There is, and always will be, a relationship between the two due to the nature of releasing a new vehicle. Some companies reduce the impact of releasing a new vehicle by keeping the underpinnings relatively the same with many exterior and interior tweaks or by limiting the amount of updates a particular vehicle gets. An example would be to release a new powertrain setup mid-cycle on a vehicle and then keeping a proven engine combo for a new architecture.

All manufacturers have issues. Google Mercedes balance shaft and you will learn about how all the 2006 ml350s, e350s, r350s have defective engines that require a $7000 repair likely between 60,000 and 100,000 miles.

Angry Re: I Think I Fixed My Rough Shifting 8sp Transmission

Hello JGC Owners! I just received my 1st Jeep, a 14' SRT and I'm experiencing the "clunk" sound from 6-5 , 5-4 downshifts - 95% of the time. The clunk/bump sounding coming from the rear ( or behind me the driver ) is still present. I haven't driven it enough to see if it will work itself out, seriously I doubt it will until Chrysler comes up with a proper "software" update for this 8 speed Tranny. More than anything it is annoying and hoping its not causing any "long-term" type of damage. My build date was 9-15 -- Took it to the dealer already, which is sad in itself when you have 400 miles on a brand new 69,000k vehicle.
They said that the "SRT" had a more aggressive shifting patterns. I just shook my head as that has nothing to do with a "clunk" sound. I haven't driven it enough yet to determine any other shifting issues, but I do agree with everyone that it also has a very "Rapid" downshift/coast and the 2-1 shift can be almost "tricky". Even with ECO off, I can be in 8th gear doing 40 mph, which should only happen in ECO mode. I'm barely at an idle when matched with that speed and gear! It should honestly be at the least be in 7th gear!

I also read where another user said it could be the driver , lol --- but I know its not me. I owned a 2008 Lexus IS-F ( which had a 8 speed btw ) and it completely makes this one feel like junk, IMO. I hope someone at Chrysler will figure out the "proper" parameters for our JGC's 8 speed tranny's! --- I received it with 10 miles on it, so it could be possible in its "early" stages of learning that it was "confused", if you want to call it that.

Maybe the battery reset or fuse reset, etc. will work, but for how long really since some reported now its coming back?, regardless. Some report it has indeed made it worse, but a majority concur it helped...
~Yep, its frustrating - I like the JGC-SRT, but the tranny I can tell over time is going to get extremely annoying in stop-n-go traffic.

PLEASE FIX THIS CHRYSLER! You are going to start running off new customers who are supporting a U.S. mfg. vehicle! This is unacceptable in any vehicle, let a-lone a 70K dollar one! My 2006 Mazda 3 that has 140K miles on it shifts better than this JGC-SRT!!

I agree . You should contact Chrysler and tell them what you just told us. After 3 updates my v6 8spd is almost perfect. I hope they keep trying to improve it. Good luck!!!

99% of the people in this thread are talking about the 8 Speed with the V6. There have been virtually no complaints about the ZF Built 8 Speed in the V8 / Diesel and SRT.

It sounds like you have some other problem going on as I think I have only ever seen one other person here with that transmission and what you are describing. Hopefully your dealer can look into the issue further but I don't think there are any shift updates coming for the SRT.

As for being at nearly Idle and in 8th gear, yes that is exactly how ECO mode works on the 6.4. If you want it to run the gear ranges higher, turn off Eco on startup.

Re: I Think I Fixed My Rough Shifting 8sp Transmission

For any of you that had the update done:

Are you still having problems with the rough transmission?
Did the update correct the issue? or the issue returned after a while?

I have a GC V6 that I took delivery in April .. Unfortunately my dealer is refusing to install the new update. After several attempts showing them the TSB, RRT, they still say that my GC is fine and my VIN is not included on the list of affected cars. And on top of that they are saying that I have the latest software. How can I have the latest software if I took delivery in April is something that it is beyond me. Has anyone had this GREAT experience with your dealer?

Thanks!

You need to call Chrysler customer care and complain about the dealership service department, and find another dealer. Or just write an email to the service manager that is unacceptable.

I would call Chrysler customer service (assist button in rearview mirror. Politely ask them for help and mention any issues you are having with your GC And then ask if you have the latest software fixes/versions. From your description it probably will be a resounding NO and if so ask them how you can get the updates because your local dealership says you don't qualify. This should get the ball rolling.
