So I bought my Cherokee about a month ago and have had the 2nd gear wobble, the rough shifting from gears 1-4, the revving and high RPM's in 4th, and basically the rest of the problems with the transmission. All my problems are intermittent and don't happen every time, except for the 2 gear wobble when I accelerate uphill. 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.
