Re: If your 8spd trans is rough, put your hand up

Most of us who elect to make a $40k+ purchase for a Jeep Grand Cherokee would appreciate the understanding of the dealer or the manufacture acknowledging that the pause in acceleration, and jerky transmission is being addressed and will be remedied with upcoming TSBs or comprehensive SW updates. This is not an anomaly or unusual circumstance. It is incomprehensible for me to grasp as a 6 time Jeep (Cherokees, Grand Cherokees, and Wrangler) customer that I have to fight-now legally- with a corporate entity to get a meaningful resolution. The dealer flat out denies that there is an issue with my vehicle (04/14 build-Limited) or any others. Their alleged expert (who by the way is an expert ONLY in Chrysler products, paid ONLY by Chrysler works ONLY on Chryslers) is brainwashed into believing this strangely behaving transmission is 'normal' or 'characteristic' of the 8 speed. If it's 'normal' why are are there any 'flashes' at all. Leave it alone if that's how it's to operate. This has gotten out of control, and will likely end up in a class action suit or significant recall. I'm interested to see if this assertive acceleration pause when merging into traffic is ultimately going to cause a serious accident?

Re: If your 8spd trans is rough, put your hand up

I'm taking my 2014 overland v6 in for the third time tomorrow. They are applying the drive/learn process, so we will see.

If they don't fix it, I will step into the GMs office and give them one more chance, then I will declare lemon law.

I also have a local dealer willing to swap me for a brand new 4runner limited. I'll give them $600 a month the next 4 years instead.

Re: If your 8spd trans is rough, put your hand up

My 2014 V6 overland has shift issues still though not horrible in ECO they still exist, sport mode on the other hand last I used it was horrible, all flashes supposedly applied but the re-learn hasn't been done yet, dropping off with Dealer next week to see what happens.

Re: If your 8spd trans is rough, put your hand up

Keep in mind guys a "relearn" can be done by unplugging your negative on your battery for however long. This is why I never accepted this as a fix from the dealer as it's a BS reason to get you out of the service bay and out of their hair.

With that said mine was done and shifted BEAUTIFULLY for 300 miles than went right back to shit. I refuse to accept that my driving habits makes it shift shitty.

This problem is real. I think it likely exsists in all models but like a few posts up mentioned, likely less noticeable with the V8. I've had scenarios that I found downright dangerous as my vehicle refused to accelerate until basically flooring it and it redlining the engine.

To me it's clearly programming and likely a major issue with the "adaptive" learning feature. My 2014 Wrangler with the 15 year old 5 spd shifts flawlessly.

I'm sorry but when I spend $50,000 on an American-made SUV I expect it to drive properly and not be in the garage every other week for the same issue.

Clearly if Chrysler is offering to pay me not only my downpayment but also all of my monthly payments I have made so far there is a specific problem that they are unable to resolve.

Why don't you keep your negative comments to yourself and stop judging us members who simply want a vehicle that drives correctly. Saying that our "driving style" is causing the issue based on your "experience of 3 well made vehicles" is simply idiotic as that is 3/400,000 vehicles on the road or .000075%

Get your facts straight before spewing your pompous comments.
I completely agree. So many of us on this forum are having exactly the same issue that I highly doubt this is an isolated problem at all. Now that the weather has warmed up here, the shifting is better but my downshifts are still harsh. I'm certain that as soon as the temperatures drop I'll again get whiplash from that first cold shift between 1 and 2. I'm not exaggerating (well not all that much). On mornings below ~40F this thing will hold 1st way too long then slam into second on that first shift. This has nothing to do with economizing.

I'm curious though if our problem is somehow related to how we are using the vehicle (since apparently there are a few folks that claim there vehicles are shifting fine ). My driving is mostly short trips in stop and go city conditions and infrequent highway. Is this something we might have in common? Also, as I've indicated, the crappy shifting is more pronounced in cold weather.

Re: If your 8spd trans is rough, put your hand up

Totally agree about the cold shifting. I just use the paddle shifter to upshift for the first pass through the gears then go back to D. I consider this temporary while I wait for better software. It becomes second nature once you have comfort with the paddle shifter.

I agree 100%

Almost had an accident myself the other day cause the Jeep took off like a rocket after just slightly touching the gas-pedal. I had my 3-year old son in the back!

My 2014 Limited CRD has a 04/13 build date and the transmission was fine - until they flashed the latest update!
There is no way back to the older software version and niw I have to go in for the damn "learn-process".

I wish they would stop experimenting on their customers and just telease 100% tested Software. And by "tested" I mean ALL models. Diesel, 3.6, Hemi and SRT..

Re: If your 8spd trans is rough, put your hand up

Well, I have to say that my transmission is back to it's old self and dare I say even worse. Tried the battery, fuse and relearn procedure to no avail.

Even worse, I don't know if any of you have experience this, I was on a long stretch empty road one night and decided to try out the paddle shifts, when flooring it and shifting from 1st to 2nd, there was a terrible shift delay making me hit the redline. I have duplicated this 2 more times thinking it was a one time thing, has anyone else encountered this?

I have to make an appointment now with the dealership now to get the trans checked again, they give me a loaner car but I seriously have no time to be going to the dealer so often.

I have tested the paddle shifts many times. Not a problem here.

However, I have had so many issues and lost so much time with this Jeep - called my dealer and said I want to return it. I have had enough.
I will gladly trade for another Jeep with a later build, but this Lemon is driving me insane and makes me cry for the Money I spent!

Re: If your 8spd trans is rough, put your hand up

I have had a number of issues with the transmission, primarily with the shifting in and out of 1st and 2nd gears being rough. I finally convinced the dealer to take action and they replaced the SOP control valve. Since I've picked-up the car yesterday, the transmission has been running very smooth and what I anticipated when buying a $45K vehicle.

For anyone continuing to have issues with a rough transmission shifting (my build date was November '14), I suggest you get the dealer to replace the control valve, it has worked wonders so far.

Re: If your 8spd trans is rough, put your hand up

Mine is there now and is done with recall. I mentioned the trans shifting crappy. If it still does I am going to tell them to keep it till it's fixed.
