Re: Harsh Shifting

I have a new build ( March 2015 ) with the 5.7 Hemi and no issues, and my neighbor has a 2014 with the V6 ( Aug 2014 build ) and says he's never had an issue either.. I would agree with Snofire's reply to give the beauty a test drive .. vrroom, vroom..This is my second JGC ( I traded a 2011 for this one )
and if something happened to this I wouldn't hesitate to get another.

Re: Harsh Shifting

I've owned two 2014 V6 Grand Cherokee 4x4's, and BOTH had rough shifting transmissions.

And a test drive won't necessarily reveal if the Grand Cherokee has a transmission issue or not...case in point, my 2014 Overland V6 didn't start having transmission issues until it hit about 5,000 miles.

My advice...get the V8...better transmission, and insure the vehicle has had all the latest updates implemented.

Re: Harsh Shifting

I have a 2015 Overland with V6, build date 11/2015. I just got the latest TSB applied last week. They performed a quick relearn and said it will settle in about 300 miles. Not quite there yet.

I do notice once the transmission temperature gets up to 120F or hotter, transmission shifting is smooth and I have no complaints. Before this temperature, I still notice, albeit a less harsh, 1-2 upshift in non Eco-Mode. It's not as bad, but it's still there. The rough 4-3, 3-2 downshifts in Eco-Mode appear to be resolved once transmission is up to temperature. I still can't believe Chrysler has sorted the V6 tranny out yet.

Re: Harsh Shifting

Mine has been rough shifting on the 1-2, 2-3, and 5-6 shifts when cold for months. I've had the valve body replaced last August along with numerous code updates since. I took it in again this week to leave with service. As actions, they've attempted additional code updates without resolution and opened a case with Chrysler. Chrysler is now advising them to replace the valve body again. If that doesn't do the trick, Chrysler is authorizing a new transmission. In our household, we have a Ford Fusion, Chevy Tahoe, and Chevy Camaro besides the Jeep, all of them shift like modern vehicles, I don't understand why this is so hard for Jeep.

Re: Harsh Shifting

Does anyone know the exact number of miles required for these new transmission to complete their "learning mode" ???? I have heard everything from 300 miles to up to 6000 miles.... I also discovered this on mine.... After an update or reprograming, and the trans is in it's so called learning mode, if I always drive in "auto" mode the trans is not too bad, but if I put it into "SPORT" mode, even once, the next time I drive it in " AUTO" mode, the trans returns to it's weird rough down shifts and stays that way in all drive modes from then on, unless I disconnect the battery and put the trans back into learning mode.... This is still after two new valve bodies and all updates.... I guess I will push for a new trans next

Re: Harsh Shifting

Mine was flawless until 4500 miles.. then the transmission started rough shifting 2-3, 3-4. At around 6200 miles I took it for the service and to flash the latest TSB. This improved 3-4 but 2-3 is still harsh... Last week they performed quick learning procedure but no luck with 2-3. I am waiting on next step, hopefully valve body will fix my issue as it did to some. Once the transmission is around 120°F all gears changing without problems.

Re: Harsh Shifting

Until transmission temperature hits 130F or higher, I have less-than-desired shifting. 1-2 is terrible and lunges forward every morning until its warmed up. I don't notice 2-3, but I do notice 3-2. This behavior cheapens the vehicle and brand. This should have have been caught in testing during 2013. You can tell Jeep has no idea what the hell they are doing, there seems to be transmission updates for 845RE every month. I have the latest updates from WK2 TSB page. In fact, I just got it back from the dealer 2 weeks ago.

Re: Harsh Shifting

I have a 2014 GC Limited 3.6L auto. The harsh down shifting started at around 5k miles. A TSB seems to have fixed it. However it does happen occasionally during hard stops. Hope this helps.

Re: Harsh Shifting

For the folks that commented the shifting is harsh when cold, does everyone have the two speed transfer case? I haven't seen complaints on the Durango forum on vehicles equipped with a V6. They only have the single speed transfer case. Seems insane that a vehicle in this class has a transmission that shifts worse than a tractor when cold.

Re: Harsh Shifting

I should add If the Grand Cherokee didn't drive so damn good when it "works", I would have dumped it long ago.

Re: Harsh Shifting

I got an update from the Service Manager Thursday afternoon regarding my transmission status. As stated earlier, Chrysler recommended a new valve body, so the service department pulled my existing valve body out Thursday morning to prepare for the new one arriving late Thursday/Friday morning. Well...the tranny is toast. When they pulled the valve body, they found lots of metal chunks in the pan. New transmission should ready to go by Monday. So, if you are having the rough shifting when cold insist it gets looked at now. You don't need to have issues with warranty when your vehicle has 50,000 and needs a new tranny that Chrysler refuses because the condition existed for the last 30,000 miles.

I hope this takes care of it once and for all.

Re: Harsh Shifting

I've been dealing with my own transmission issues with my 2015 WK2. Just had valve body replaced today. Fun times!
