Am I reading the first bullet correctly in thinking the Eco might behave like the 2015s and retain settings after the car is turned off and back on again?

I'm thinking I'll give this a shot, but...

Less than desired engine braking during downhill descent.
Haha, I have the *opposite* problem. I have never driven a vehicle that required more power to go downhill. All too often I find myself shifting to N to keep from slowing down.

Parking garages are the worst. Really have to give it a lot of accelerator pedal encouragement to have the Jeep obey gravity. I usually just coast in N instead.

The last TSB was supposed to fix the transmission bump. For me it was less harsh but more often. Hope this is a real fix for that problem.

Re: TSB - Shift improvements for 2014 3.0L Diesel (Feb 28/2015)

wonder if this will also do anything for the folks having MPG impact from the other flashes from the DEF/CAT issues and the shift patterns?

Please read the first paragraph of the TSB. Jeeps's revision TSB's mark the added features in that TSB with asterisks, so the only item this revision fixes on top of the previous one is the Eco memory retaining feature.

IIRC, One caveat is that if you do NOT have problems, it is preferable NOT to do the reflash!

I did not have problems. I did receive the flash. I still do not have problems.

Your 2014 remembered the Eco setting after turning off the vehicle, even before the flash?

(haha)

My point was that I wasn't having issues (clunking, fishing, etc.). And I'm still not having issues (clunking, fishing, etc.). So why not go for the flash?

My point was tongue in cheek, because if the update flash doesn't "fix" anything the owner wants to have "fixed", why would they get it?

I learned my lesson after flashing a BIOS update on a motherboard. My machine had no issues but hey, "latest and greatest", right? The firmware update broke compatibility with my video card and the motherboard utility didn't allow downgrades. Eventually I had to have the motherboard physically replaced with a new one flashed to the previous BIOS revision and I never touched it again. Same scenario pertains to firmware updates for my Jeep. Obviously others have a more aggressive approach to updates. That's great... they can find the bugs for the rest of us, like, say, if the update hurts fuel economy or something.

BTW, Eco mode persistence does work for you now, right? That was the only official change. However, I'm not at all convinced that was the sole difference.

I'm trying to decide if I will gamble on getting the Eco mode memory feature vs the risk of causing new issues when I don't really have any at the moment. Now, if this update had a "seat ventilation mode memory" feature then I would be beating on the service garage door at 0500 (haha).

Re: TSB - Shift improvements for 2014 3.0L Diesel (Feb 28/2015)

From new, I never had any issues with the tranny or ECO mode on my GC diesel. It always shifts smoothly and gets great mileage....

Having supervised software developers before I retired, I learned that in SOME CASES a re-flash can exacerbate issues rather than fix them. So, given the history of previous Jeep re-flashes, I chose not to get it done....YMMV.

Glad y'alls are working fine......
