I had these symptoms under 1k miles or so.

Pretty much 100% resolved by 1500 miles. I would wait until at least then before having someone tear into your trans and replacing things.

Got an update from my dealership regarding the strange shifting/shuddering issue when transmission goes up from D1 to D2, after transmission reaches 165F-175F

Transmission valve body is getting replaced, similar to @kverk88 and @joer561 GCLs

I’m glad it got resolved for you on its own Jim, but I have about 3k miles and the issue is not going away.
Moreover, if this is something that’s normal and goes away as part of transmission break-in period or process, then I feel like Jeep should be listing it in the owners manual for customers to know what to expect

My Grand Cherokee L has 2900 miles and it shifts very weird around 10 to 20 mph. It’s almost as if the transmission was slipping. I will be taking into dealership tomorrow. Hopefully it’s just low on transmission fluid or a software update, but I don’t know. It’s frustrating. If i accelerate fast you can’t really tell, but from a dead stop and accelerating slowly once it hits 10 to 20mph it shakes almost as if it was going to stall. After that speed it drives fine. Has anyone experienced this with any other Jeeps? I traded in my Jeep Cherokee and never had any problems with that one.
Yes, and I just happened to jump in here looking to see if anyone else has experienced the same.

Speak of the devil, it did it a time or two this weekend.

Still very infrequent at this point.

Sorry to hear things aren't resolving for a lot of you. You would think this trans would have all the kinks worked out already unless it was changed for the L?

Any one having issues on occasion where it shudders, or struggles in reverse? Mine has done it a couple of times in the past two weeks.

I can duplicate the shifting issue. Is there a TSB for it? I'd like to be prepared before I bring mine to the dealership, if at all possible.

Mine does it when shifting from Gear 1 to Gear 2 once in every 4 or 5 starts from a stop.
Sometimes very noticeable and feels like I am driving an old 5 speed and am slipping the clutch.

Any idea if that will be by request or will be a service recall?

I am test driving two GCLs tomorrow. If I want to try to replicate this issue (to see if those particular vehicles have the strange shifting issue), is my best bet to (1) drive around for a bit to get the transmission warmed up, then (2) slow down to a stop, and then (3) accelerate from first to third gear & see if the vehicle lurches, clicks, or otherwise behaves strangely? Is there something else I should do to try to replicate the issue? Also, where does the GCL display the transmission temp -- main gauge cluster?

Thanks much.

Mine does it all the time, transmission temp doesn’t matter. Mine also has an audible click when it downshifts from 2nd to 1st every time. But dealer “couldn’t duplicate” 🙄. I have to take it in for first oil change next week, and tell them to try again.

Yes. I noticed it too. But think I was getting used to it. My wife was in car the other day and it slipped/shuddered and she was like what was that? We have almost 3k and hasn't gone away. Sounds like a universal issue. Hope there is a fix and it's not doing long term damage to transmission. Keep posted on any latest updates here

Took Jeep in for oil change and the shifting and clicking at downshifts again. I’m sure it “cannot be duplicated” again. Will keep y’all posted

So they were able to replicate all issues. Service tech said “transmission is still learning.” I have over 5200 miles on the odometer. Said the click sound was “normal”. As it is the active 4wd actuator. And the shuddering in reverse is the “active hill assist system”. This occurs in my flat driveway and flat parking lot at the office.

The service manager actually pulled me aside when I picked it up and told me he disagreed with the service tech’s diagnoses. And that he was going to do some research over the next few days and give me a call.

On uneven terrain jeep was struggling to reverse uphill seemed lil lack of power was concerning in moment had to abort attempt as was unsettling and seemed like was struggling w 1 tire spinning could've been jus tires struggling. V6 4x2 limited. Monitoring this thread have over 6k miles on mine haven't noticed anything particularly unsettling in drive mode but in sport it does seem to have irregular high rpm when decelerating abruptly at times esp from 2 to 1st think takes while to downshift. Could jus be breaking in suppose seems to be handling better now, broke engine in on long cross country trip.

Anyone have issues with noticeable downshifts, especially in the middle gears such as 6 to 5 or 5 to 4? I have about 500 miles on my JGC L and don't have the shudder issues on the upshifts (thankfully, but knocking on wood). Mine has fairly noticeable downshifts as if I I am manually downshifting, hard to describe, but the shifts from 6 to 5 and 5 to 4 are fairly noticeable especially when decelerating from 45-50 mph for a traffic light, etc. when compared to barely noticeable downshifts across the other other gears in the 8 speed. Thinking it could be valve body issues acting up or perhaps a solenoid not firing right.

I have a GCL Limited with about 900 miles and I think I have pretty much the same thing going on. As you mention it is hard to describe. The acceleration seems ok, but it does feel like a manual downshift when I am at lower speeds. I have been thinking when the downshift happens it enters the lower number gear at two high an RPM. I have been debating on taking it to the dealer, but have been monitoring it trying to figure out how to be describe it to them.

Yeah, this sounds like the exact same thing to what I am experiencing. I'm holding off on taking to the dealer right now given low mileage in the hope that it resolves after a few more miles and/or an update comes out soon that can be applied. Your description makes perfect sense to me though.
