Re: Another 9-speed transmission thread.......

HAve a 2015 Latitude 4 clinder as a free loaner while my PT GT is having a timing belt done.

Anyhow, quite impressed with it, I was expecting quirky shifting from all I have read, but seems to be in right gear all the time and cant really tell when it is shifting.

Poped it in sport mode and it would hold higher shift points.

Note I have the 8HP70 8spd in my 15 Hemi Overland so I am familiar with the ZF units.

Also someone mentioned other makes are not having teething problems with the ZF 9spd, but lots of complaintes on the Acura boards, believe they are going thru the same issues Jeep did on the14's.

I have a 2015 v6 and its a lot better than my flashed 2014 v6. I dont understand why there having troubles with the 2015 as i got 18,000 miles on mine and not 1 bit of trouble. Some times when i slow down to make a right turn at a corner and after the turn ill give it gas and sometimes ill catch it as its down shifting and it will clunk going into the lower gear but thats it.

Re: Another 9-speed transmission thread.......

Here is another fix....4 weeks ago I had the ENTIRE transmission replaced on my 2014 KL. I took the jeep in for a Vermont state inspection and the tech noticed a transmission fluid leak. The vehicle is still under warranty so back to the dealer. Short story, the transmission housing had a crack and the solution was to replace the entire transmission. Fine with me; so far no issues with the new transmission. The tranny came in overnight to the dealer from Boston and was installed in two days. Zero $$$ cost to me.

Re: Another 9-speed transmission thread.......

Before buying my 2016 Cherokee KL, specifically inquired about this transmission problem at 2 different Jeep service centers. Techs at both centers said they had not heard of the problems. However, I'd read about this problem here and in mainstream news media reports.

So far, driven less than 2k over a variety of on-road and off-road conditions. The transmission ran smoothly running errands in town, at freeway speeds and on steep off-road unpaved trails. Really like how cruise control automatically downshifts when descending downhill to maintain a set cruising speed.

From what I've read, 20k miles seems to be when problems usually appear, if there is a problem. Anyone know where to find a summary of how many transmission problems were reported out of which years and models? Along with how many of those years and models were sold in total? I'm of the impression only a relative very few unfortunate owners got stuck with faulty transmissions.

Re: Another 9-speed transmission thread.......

I doubt that Jeep will admit to having issues...They do have issues with this transmission. Period.

I did see a new TSB - Anyone try it?

Re: Another 9-speed transmission thread.......

well you are lucky talking about the calibration of the transmission..... i can't say anything as I'm waiting for the 2nd transmission to be installed.... mind you driving replacement Trailhawk and it's great compared to my Limited which not surprising, became noisier after the 1st transmission replacement and the front end wobble didn't help either (which they fixing now).... i can taste that fruit they call lemon coming on...

The issue with the transmissions seem to be resolved somewhere mid 2015 production.
At that point it seems that a hardware/software change was made to the transmission.
I know the FCA had several TSBs, most notably the RO1 last year that involved removing 2 on the downshift. The RO1 made a note that the update was for "durability" issues.
The RO1 also had a stress test for the snap ring in the transmission and repositioning of it on a new ring install if needed.

The transmissions produced before the revision with the older software are either functioning well or are problematic. Mostly I would assume due to the AL system (older software) which can cause rough shifting and other abnormalities well past the point of when AL should have been finished. These things particularly rough shifting and jerking will cause wear to the transmission and shorten its life considerably. I would also say that if the vehicle can not attain a smooth shifting pattern via software updates the transmission will most likely need to be replaced.

Now what leads me to believe this is just very recently FCA released a TSB for the transmission that returns 2 on the downshift. This TSB only applies to Cherokees built after 3/2/15 (if I remember correctly). So obviously FCA has resolved the durability issue via a hardware change in the transmission at that point. It is also mentioned in this forum that new hardware/software is in the 2016 transmissions.

So it appears that FCA had the issue figured out with the RO1. The only solution at that point was a software fix on existing Cherokees, removing 2 on the downshift.
As of 3/2/15 produced Cherokee's the new hardware was in the transmissions and new software and/or adjustment of was implemented on this latest TSB that did not apply to pre 3/2/2015 builds.

Mine is one of those, a 12/11/13 build. My transmission is perfect at this point in time. I do not have 2 on the downshift as that was removed on a May 2014 TSB. I do not ever expect to see 2 again because a hardware change would be needed to the transmission to allow it.

Also all updates are VIN specific to your Cherokee. Its not what works for another Cherokee. In my case my Cherokee only has had 1 update that was required.

A transmission that is rough shifting etc. after reasonable attempts to be resolved by the dealer needs to be replaced with a NEW post 3/2/15 transmission with the new hardware/software. This is especially true if the vehicle was built prior to the introduction of that updated transmission, which I assume was around 3/2/15.

Jeep is not going to replace all those pre hardware updated transmissions.
The problematic ones will be replaced under warranty as needed. I am further guessing that they will also be replaced out side of warranty on a case by case basis.
In general I believe jeep will be very proactive in replacing these transmissions if any problems start developing.

Last year my dealer told me that if I notice any change in the operation of the transmission bring it in and they will deal with it.
I have feeling that dealers/FCA will more proactive going forward on this issue. Just work with your dealer to resolve your issue.

Now understand that is my conjecture/opinion on the subject from 2 forums and the TSBs that have been released.

Re: Another 9-speed transmission thread.......

I've got a 9/2014 production 2015 Cherokee with 27,000 + miles on it. I've had the required recalls performed. I have never had an issue with this transmission either before or after the recalls.

Just my $.02 worth
