Re: FLASH: TRANSMISSION SHIFT ENHANCEMENTS (vehicles with 3.6L engine)

Just dropped off the Jeep at the dealer. Wasn't in there system yet but I had some other work for them to do. They're going to look into the tranny issue.

Re: FLASH: TRANSMISSION SHIFT ENHANCEMENTS (vehicles with 3.6L engine)

I went to my dealer to try to get this update. No luck. They said my Jeep isn't part of the recall??? I have a 2014 Jeep Grand Cherokee V6 that I bought in March. I also tried to have uconnect software updated but no luck there either. They said since my car doesn't have a CD player, they can't update it since they don't have a USB drive. Chrysler really needs to get their crap together.

Re: FLASH: TRANSMISSION SHIFT ENHANCEMENTS (vehicles with 3.6L engine)

I was told the same thing; that there is no TCM update available for the transmission. However there was an available PCM update for the engine which was flashed onto my car. I took delivery of my car on 23 April 2013 so it should be included in the affected vehicles.

The PCM update, however, did improve the shifts. Given the current state of UCONNECT updates, I would not be surprised if it was coded wrongly in the system.

Following the update:
  • In ECO mode the car is even more subdued - read SLOWER
  • In ECO mode, and normal pedal press, the car revs up to 1000 rpm and 7th gear, even when cruising a 30 mph. I do not recall 7th gear at 30 mph before now. A more aggressive acceleration elicits revs up to 2000 rpm and slightly more response.
  • In ECO mode, the rough UP and DOWN shifts are gone. This, along with the new behavior of the transmission (gears and revs) makes me think that I did get the tranny flash and not an engine flash (but who knows).
This is the list published by Milous

http://wk2jeeps.com/wk2_tsb.htm
I was unable to see any 3.6L PCM (Power Control Module) reflash (engine reflash) published at that link.

I was also told at my last visit that they reflashed the PCM. Was not aware there was an update.

Sounds like your dealer sucks. Tell them to go out and buy a new computer with a cd drive and a usb port. Its really hard to believe a dealer or any business for that matter would not have already have one.

That is the stupidest thing I have heard. They received a letter June 17th advising them to prepare USB sticks for the RADIO update.


There is no recall, it is a TSB and these two items should not be confused but they clearly have no idea what is going on.


None of this is on Chrysler at all, your dealer has no clue how to fix cars.... All dealers have access to this update.

Funny thing is that I'm on my 2nd dealer. Time to go to one a little further away. Sigh...

Go to Milo's site and get the TSB. Very easy, follow the link a few posts prior. Reference the TSB.

I just can't believe you asked about a transmission update and they said something about a USB stick. I would run far away from that place.

Honestly... It is stupid simple. They plug in their Wireless Star module or pod and it will tell them via the WiTech system there is an update. If you want as per my previous comment, note the actual TSB number in case they won't let you that far.

Re: FLASH: TRANSMISSION SHIFT ENHANCEMENTS (vehicles with 3.6L engine)

Maybe those who have success can let us know the dealership you went to. That may save those who are in the area a trip to a clueless dealer.
