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

Some have had luck disconnecting the battery and pumping the brakes a few times to discard any remaining charge in the system. Some have reported an improvement others only found it to be a temporary solution. I tried it several times and had no improvement.

As far as the software version goes. You will have to take it to a dealer to verify what version you have. I wish it would show it on the screen at start up, but I don't think Chrysler wants you to know what version you have. Just my .02.

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

My JGC is back from the dealership and I have graduated into the class of transmission valve body replacements. When they called to tell me it was ready to pick up I asked them why they replaced the valve and what was wrong with it. He told me they found a short in it. When I talked to another service guy at the dealership he mentioned nothing about a short and said their is a TSB out that mentions replacing the valve body. They also updated the PCM and performed a quck re-learn. We will see what happens in the next couple of months.

While checking out I asked him about their experience with 2014 JGC transmission issues. He said they have not received in a lot of service visits and really none on the 2015 models. However he and another guy standing there agreed the 14/15 Cherokees are a nightmare. Pretty sad.

14/15 Cherokees are a nightmare because of the transmission or otherwise?

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

Good news! Got a call tonight from Jeep Resolution. They're going to go ahead and replace my SRT! I should be getting a call in 6-10 days from another person to work out the details. I'm just ecstatic and yes I asked her if this was an April fools day prank.

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

Our has very rough shifts between the lower gears. I mentioned it to the service manager today and he documented it, however said there's currently no TSB available.

They go by VIN and none of them matched up for MY15.

??? Actually, almost all ate build date and config based. VIN is only used for the Recalls and CSN's.

Something is crossed up it seems. We want to help.

Sorry to hear that. It seems like the are coming out with new TSB's all the time. Hopefully it can be fixed without getting into the mechanicals.

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

Some have had improvements with the last SRT Trans updates. I'd double check. Maybe with a different dealer.

Sorry, wasn't trying to be snippy, that was just the explanation I got today. Was told they entered my vehicle into the system and no updates came up. Build date was Nov/14 I believe. He explained that it was VIN-based but maybe he was just trying to dumb it down (or talking out of his posterior). Is there's a way I can validate that myself?


I personally thought this one applied but was told it didn't.

I wish we could just do our own updates.
