Is this issue mostly with the V6 trans or have there been an equal number of issues with the 5.7L trans as well?

V6 only.....v8/diesel/SRT are same unit with only a reflash and some minor shifting rough edges, most seem happy.

The dealership technicians contacted engineers at Chrysler and they determined that it was a bad valve body. The service manager told me that they only needed to remove the pan and not the whole transmission to make the repair. When I picked up the Jeep the odometer actually said 1158 miles. It is going to take some time to fully trust this vehicle again with such an early failure, especially one that could leave me stranded. I will keep you posted if it develops any other transmission-related issues or if this one recurs.
Same thing happened to my 05 last year, hasnt happened again since.

I've researched this further and have found quite a few people with transmission problems / valve body replacements (V6 only). Does anyone know if they're fitting an updated valve body that corrects the issue, or if they're simply slapping a replacement in that may fail just as soon?

I will of course ask the service tech, but they may not know.

Have the SA or tech lookup the part in STAR and if it shows a # revision AA to AB or AC, etc then something as changed. Since the valve body is the physical heart of the tranny and there is no recall or TSB for part replacement I'm gonna bet that it's a manufacturing defect issue. All it takes is a CNC machine to be very slightly off or a burr left or, etc.. for a valve body to not act as designed. However, this is also the tranny that Chrysler is modifying the clutches. etc.. from the manufacturer to better handle their engine torque needs so there are also programming issues that complicate owner satisfaction. Seems those TSB's help for a while with some but then the tranny may return to slipping, slamming issues esp when cold...Many (most?) seem to be happy with their V6 tranny. Just my 2 cents. Too bad you won the lottery twice

I received a call from the dealer (Beyer Dodge in Morristown) and they were able to expedite delivery of the new valve body and the Durango should be ready tomorrow. I'm happy to hear that the repair went so quickly and commend the dealer's service team.

I asked whether this was a redesigned part and they said no, our original valve body was defective. I hope it was just a manufacturing flaw and not a design flaw. I'll have to see how our car drives and will perhaps abandon plans to switch to a Japanese minivan. The Honda Odyssey was our top choice, but I've uncovered complaints about problems with its 6-speed automatic transmission. Sounds like it might be like jumping out of the frying pan into the fire!

On my second transmission now since purchasing my 2014 Laredo V-6 in July of 2014. After a few months on the new transmission I am beginning to notice that familiar shutter during certain downshifting. It seems to occur more often when the truck is cold and going up or down an hill.

Particularly when I leave work, there is an downward slope immediately following the exit of my parking area. If I don't let the truck warm up a couple of minutes it will shutter easily going down the hill.

Interestingly, it seems to shift smoother with a trailer on the back. Trailer weighs maybe 300lbs with a 500lb motorcycle on top.

My unlce has a 2014 diesel, not sure which model, and hasn't had any problems in the six months he's owned it. We both use these vehicles for towing, and off road adventures.

Your uncle has a different tranny. He has the non-modified 8HP70 ZF (no real complaints) and u have the Chrysler modified 845RE which some (many?) echo your complaints. The non-modified version of your tranny from ZF is the 8HP45 for reference.

I have a 2014 Jeep Grand Cherokee Laredo 6cyl 8speed and have had my first transmission problem 5 months and 4400 miles in. I was just beginning to accelerate into 3rd gear when the automatic transmission shifted violently and disengaged with the "Check Engine" light popping on. After pulling off the side of the road and going into Park, I restarted the Jeep and was able to continue, although the check engine light remained on. Took it into the dealer and they updated software on the transmission. After reading a number of posts here and other sites, I am maintaining all my paperwork as this problem may be more widespread than reported. I love my Jeep, but need it to work. Getting to the dealership and having it out of service for a few days at a stretch is awful for a brand new vehicle.
