HOWEVER. Somewhere in this forum, I saw someone suggest that I turn off Hill Assist... and that helped their acceleration. Lo and behold... that **** worked! I think it worked. So @gundad, since you're having the same issue, could you kindly try turning off your Hill Asist and let us know if that improves acceration? I feel like this made a pretty significant difference for me... now my TH is driving more like the blue line indicated on my graph.
Actually my acceleration problem and skipping went away after they corrected the level of my transmission fluid. My only problem now is some random rough shifting and most notable is the clunking / feeling like I'm going to stall around 2nd or 3rd gear. But I know others are having the acceleration problem still so maybe they will chime in.

Ah, good to hear at least one issue is gone for you. For me, its only the acceleration issue. Wobble is not there nor are the hard shifts and the clunks. This is why I'm sort of hesistant to have the dealer look at my issue. With Hill Assist off, I'm pretty satisfied with how my TH is running now. If anyone wants to give this 'fix' a try please do let me know - I'd really appreciate it. I just need to make sure its not a placebo

Yeah I turned off the hill start assist. It helped with acceleration but not with anything else.

Sounds like adaptive learn still has a ways to go.
That is exactly what I went through with AL.
Stalling out feeling between 2/3 did go away. I still get a bit, very slight, but its improving.
Its not an issue at this point.
Never had clunking though.
Due to the low transmission fluid I would just keep a close eye on it.
Being as low as you were is never good for the transmission. I am also surprised that they did not remove the existing and use all new fluid.
I am glad it worked out for you.
I also disabled my hill assist early on and that may have helped avoid some of the issues.

All of my issues don't really effect the safety and are on the minor end of the spectrum compared to some people after reading all these posts. I've never had a error light come on or the anything major happen that would strand me somewhere. But that being said I bought a brand new car for a reason and it should act like brand new after only 1300 miles! I shouldn't feel the gears shifting at all, I had a 2012 Nissan Rogue prior to this and never felt a gear change in 2.5 years that was rough and it has a continuously variable transmission similar to the Cherokee's.

So my question is, I have yet to read a post with someone who had these problems fixed. Has anyone had one or all of these issues and had them fixed to your satisfaction? And if so, what did they do? Keep in mind I don't mean, that they fixed it for 300 miles, or that you had it done last week and it hasn't happened yet. I'm talking about it's been fixed for thousands of miles or over a period of months.

Thanks so much.

P.S. Mine goes in the shop next week.....I'm not hopeful.
kcgunner, I see some others have already answered and advised you, but I'll add what I've learned:

1. The Cherokee does not have a CVT. It is a 9-sped transmission with a mix of two types of clutches. There is an article on the web by Alex on Autos. He explained how this transmission is built and why it works the way it does. It will not shift like older style transmissions or CVTs because of the design.
2. Having said that, there was a transmission control module flash to upgrade the firmware that was issued in early May. If your transmission was built before that date you should get it done. It substantially improved my shifting. You still feel the shifts in the very low gears 1-2-3, but much smoother. This may be because they have very low ratios compared to other midsized CUVs. Your dealer will not call you. They only do this flash if the customer complains about the rough shifting and asks about the flash and the car was built before that date. So call your dealer.
3. The transmission does "learn" over time. (I don't know why that is necessary). I have almost 6,000 miles and I still notice some quirkiness from time to time, but nothing which is troublesome. I drive with a fairly light foot to keep my rpms down and my fuel economy up and mine "learned" accordingly. I notice when I occasionally drive more aggressively, the transmission seems to do some funny things, but nothing worrisome.
4. Some people have mentioned Jeep's bulletin on the wobble issue and have had the repairs done with questionable success. My service guy just told me they have it and he is ordering the parts to do mine. Parts are backordered and may take a while, but I'll post here after it is done. At least Jeep is working on it. I imagine they'll figure it out eventually.

Life is bumpy. Drive a Jeep.

Ok thank you for your input. I realize that this is not a CVT and it shifts differently. I only mentioned it as a comparison to a competitors modern transmission.

Well my Cherokee has about 3150 miles on it. I had all three transmission TSBs done for rough shifting and some clunking earlier. It has been shifting very smooth ever since those were done about 1500 miles ago. I had some electrical issues with bad connections causing intermittent warning lights but my dealer took care of that. Right now no problems at all. Build date 9/26/13.

I've learned that a lot of dealership service departments end up writing all sorts of BS on the service ticket just to pad their wallets and shut the customer up... they may as well be writing down "filled blinker fluid reservoir, replaced defective flux capacitor, and rotated the oil pan"... that would be just as helpful.
