Do we all have this free 1000 mile check up? Can you just bring it into a dealer

Has anyone heard anything new regarding the TSB & ECO Mode? How do you even know they applied the TSB other than the notes stating they did?

The new TSB with ECO Off is 21-012-15

You will know because ECO will stay OFF.

That's my point. TSB applied yet ECO comes back on. Multiple people on this board have had the same experience after applying the TSB.

I'm curious if there is a way to confirm a TSB was actually applied.

Re: 2014 CRD + 8-speed: MAJOR shift enhancements/improvements 08/27/14

after 4 trips to the dealer.
originally 3-4 was rough shift. dealer re-flashed.
upon refleash 1-2 only when trans under 100 degreed F. hard shift. and 5-4 anytime slammed.
Took back. left for a week while on vacation.
" yeah last time the quick learn process wouldnt learn" (so they gave it back to me like that...????)
re-flashed agian, actually performed quick learn. tech drove it home for 4 days to verify.
1-2 was better but not fixed. again, only happened when trans temp below 100 degrees.

so.......................... took it back for them to replace my steeringwheel that they ripped the leather on while they had it, and to check then 1-2 shifts again.

a week later, they didnt replace the steeringwheel, because they thought i was talking about he stitching, thye did however REPLACE MY ENTRIRE TRANS, on at 700 miles after replacement, and its perfect.
cant feel any upshift or down shift, even when driving 45mph then floor it to pass someone.

dealer tells me "there was a sensor internally that they cant fix, so the replaced the entire trans.
had my jeep for 8 days.

Hey all. I have the usual transmission issues. 2015 Overland V6. Has been reflashed, no go. New valve body, no go. It is now getting a new transmission. Hope it works better than the original. I will post results later.

All this said about the 8-speed auto is disappointing especially after being in service now for a few years. Is this transmission also as troublesome in the Cherokee with the 9-speed gearbox?

Somewhat.

I had a 2014 cherokee before I traded it in for the Grand. 3.2L v6 with 9speed and 4wd MINOR shift issues compared to the grand. Biggest issue was the lack or response when downshifting.

NO JOKE, if I was doing 45pmh, and wanted to pass someone, Id floor it. took 2-4 seconds before the trans would drop from 7th or 8th to 4th ro 5th. Meaning, I had to time it perfectly ever time. Id put my foot down to pass, and change lanes at the same time, then be completely in the new lane at the old speed waiting for the "kick back" of the down shift to go. several times I almost got rear ended because I wasnt up to speed of that lane before I got in it. (which is hard to do sometimes, because youre creepin along behind someone doing 35 in a 45)

2014 CRD + 8-speed: MAJOR shift enhancements/improvements 08/27/14

I have started a thread and bumped it several times with no responses. My 15 V6 GC makes a terrible noise shifting from 1-2 and 2-3 under hard acceleration. Is that normal? Service dept said it was

It also won't use 8th gear after 79mph. I can use the paddle shifters and shift into 8th and put it back in auto and it will stay there. It's VERY annoying since I'm frequently driving on a toll road of 85mph outside of San Antonio, TX. I had the service dept check to see if there is an update for it but they said no. It was built 6/15 so it's pretty new.
