Re: 2014 Transmission

I am having the exact same issue with my 14 limited... Its a very uncomfortable feeling when that lurch happens... Apart from this, I also feel the THUD n feel a jerk when I shift from Part to Reverse or Park to Drive... I took it in to the dealership and have an appt on wednesday... The service manager was able to feel it as well and he said he will look at it and any possible TCU updates... Hopefully they get this s/w update out soon...

Re: 2014 Transmission

quick update... the dealer had my jeep the entire day... according to him, the shift points are normal, there are no TCU updates and no error codes.. its working exactly the way its designed to work it seems... guess we will have to wait a little longer for the fix

Re: 2014 Transmission

It is in traffic where I feel the slow acceleration the most. I say "feel" I guess I mean that from a stop I am not smoothly keeping up with the guy in front of me as he accelerates away without having to "punch it". So I am experimenting with the combination of turning off ECO and using Sport Drive. I only have 600 miles on the GC so me and the car have a learning curve. Also I have not yet experimented with the paddle shifters which might be another solution.

But just driving through the neighborhood I don't think about it. I like the idea of having an economic shifting selection but I don't intend on letting it get in the way of my moving on down the road. I push the ECO button off when I think I'll need a faster takeoff.

We also have a 6 cyl Buick Enclave. It's acceleration from a stop is faster and smoother when comparing it to the Jeep's ECO mode. The Buick gets about 18 MPG. It has no ECO mode selection. I think this is another confirmation that there is no free lunch.

I like my new 2014 GC and enjoy driving it and am sure I'll learn the correct way and timing to match my driving needs. SteveG

Re: 2014 Transmission

I'm going to jump on the "thank god you're all saying this, I thought I was crazy" bandwaggen. I didn't really notice it until 500 miles, but I really hadn't driven it for more then 10 min intervals-then I started getting creep in my upshifts from 1->2 (especially) and 2->3 and rough downshifts...and I thought, crap, I've got a bad solenoid and of course once they break this tranny open it will never run right again...I called my service manager who said to give it more mileage as it has an adaptive transmission and is still getting used to my driving style--not to mention he said if you drive it hard one day and sit in traffic the next, the tranny will be a little rougher then usual because it needs time to "adapt." Arg, perhaps they will have a flash soon--for 42k, this thing should run smooth.

Also, please email jeep about the eco mode-a squeaky wheel gets grease. I've done so, asking them to: sure, default it to "eco on" but let the driver choose whether they want it on or off and then let the vehicle remember that--last I checked, I own the car, not the EPA.

Another owner with a similar issue. My '14 JGC SRT does a lurch/shudder during downshifting. Have about 1.1k miles on it. Service manager said if it continues it may need reprogramming or more break-in time. Will take drop it off in a couple weeks.

Re: 2014 Transmission

Same issue. I took my '14 Grand Cherokee Limited with 450 miles on it into the dealership today. After 3 hours of testing, they said nothing was wrong with it. I then asked the transmission tech to ride in the car with me to prove him wrong. After getting to about 35 mph and letting it just coast, he definitely felt the strong downshifting when getting to about 25 mph, then 15 mph, which was obtrusive. He said it might just be the way these new 8-speed Grand Cherokee's are made. I didn't buy it. I asked if a future software update would do the trick, and he strongly affirmed me. So it's looking like we'll just have to wait for the software update.

I bet if you asked him about winning the lottery in the future he would say yes too. Believe it when you get the update and it fixes it.

Re: 2014 Transmission

I think we all need to relax a little bit and give it some time to break-in and adjust. Maybe I'm just one for wishful thinking but my '14 Limited was doing this from the get-go as well. I've got 1,500 miles on mine (800 of which was pure highway driving on a beach trip) and i'm starting to feel like the issue is working itself out. I still feel the lurch or thump from time to time now but it's getting less frequent. Then again, maybe it's just not phasing me as much anymore or i'm getting more comfortable (read: agressive) with this vehicle. It almost feels like if i jump on the gas a little harder from a stop sign, it'll rev 1st gear higher and then shifts smoother into 2nd. If I would baby it, it would want to shift into 2nd right away and give that lurching feeling. In any event, I haven't experienced that hard 1-2 lurching at stop signs during my last few city trips that were common early on. Here's to hoping that the vehicle is just breaking in and figuring itself out. I've got an appt at the dealer this weekend to install the step rails so I plan on at least asking them about it to see what they say, if anyone else has mentioned the issue, etc etc

I turn ECO mode off when im in stop-and-go traffic and it seems to help a lot...I haven't tried sport mode yet. I do have an appointment tomorrow to repair a scratch when I took delivery and they said they will also look at the tranny to make sure everything is normal.

Please post pics of the side steps!

Re: 2014 Transmission

Perhaps a little light on the horizon...I called to put my car in for service because my transmission is lurching from 1st -> 2nd on the up-shift and banging from 3rd->2nd on the downshift (oddly it happens worst when the transmission has fully heated up). If nothing else, I want it documented so when the tranny falls out of the car at 11k miles, I can say "I toooollld you!"

The service manager says he has heard about complaints regarding the '14 transmission and he believes they can now download some updated software to maybe help with that, change shift shift points, etc...

I don't know if this is true, false or he's confused but it goes in on the June 3rd (apparently everyone wants their cars fixed for mem day and they're busy) but I will keep you posted on the results.

Re: 2014 Transmission

Add me to the list. My 14 GC Overland v6 (900 miles) does the same thing. Bang when almost coming to a complete stop (but not always). The Eco mode is a killer when starting off from a dead stop (especially up hill). The guy behind me almost hits me since they don't expect my brand new big Jeep to barely be doing 25 mph when the rest of the traffic is now doing 40.

I have to turn off the Eco mode when traffic is around me or starting off up hill but I like it back on to allow the transmission to shift up into 7th or 8th when just lugging along and not needing to waste gas. I hate having to turn it off and then back on when it hits 3rd gear. Pain in the butt.

I wish the Eco mode would allow the high gears when you are running 35 mph or more but not shift from 1-2-3 withing 15 mph of a dead stop causing the guy behind you to almost hit you.

And yes, the Bang on the 2nd gear downshift needs to be fixed via software.
