Pulling onto the highway and punching it used to be a scary experience, but now I can confidently throttle up and the transmission instantly responds to my needs.
I'll have service done on that new TSB next Thursday, ECO Button matters a lot to me. I much rather have the vehicle respond quicker.
What I learned from this: Never a heavy SUV with a 3.6l gas engine again.
Either turbo diesel or any kind of boost for quick pickup. Probably a personal preference. I love low end torque, I can count the times on one hand where I revved the 3.6l engine up to 6400rpm to get max. power...

And, unfortunately, hyper 4's and 6's r the future for most vehicles. Torquey 8's will move further out of daily drivers and more towards special applications. I'll keep buying 8's as long as I can. --

No joy folks, still will not stay off. You must have to get the individual update for it to work.

Hmm, that's not good.
When I read the TSB my expectation would be that the setting is retained after the re-flash.

WK vehicles equipped with a 3.6L engine (Sales Code ERB)
• **ECO mode will not retain settings. If ECO mode is turned off, it will turn back on
after the ignition is cycled.**
• Software to correct a harsh bump feel during a 2-1 downshift.

REPAIR PROCEDURE:
NOTE: Install a battery charger to ensure battery voltage does not drop below 13.2
volts. Do not allow the charging voltage to climb above 13.5 volts during the
flash process.
NOTE: If this flash process is interrupted/aborted, the flash should be restarted.
21-004-15 -2-1. Reprogram the TCM with the latest available software. Detailed instructions for
flashing control modules using the wiTECH Diagnostic Application are available by
selecting the “HELP” tab on the upper portion of the wiTECH window, then “HELP
CONTENTS.” This will open the Welcome to wiTECH Help screen where help topics
can be selected.
2. Clear any DTCs that may have been set in other modules due to reprogramming. The
wiTECH application will automatically present all DTCs after the flash and allow the
tech to clear them.
3. Turn the ignition off, disconnect wiTECH and let the modules go to sleep.
4. Start the engine and monitor the transmission temperature on the EVIC.
5. With the vehicle located in a suitable area, perform the following steps to help enable
the transmission to quickly warm up to minimum of 55C (131F).
a. Apply the service brake.
b. Shift Transmission from Park to Reverse.
c. Shift Transmission from Reverse to Drive.
d. Accelerate the vehicle to minimum of 45 mph to allow the transmission to cycle
through each gear.
e. Drive the vehicle until the transmission temperature reaches 55C (131F).
6. Reconnect wiTECH to the vehicle.
7. Check for TCM DTCs that may have reset.

Wonder if they didn't perform the flash properly.

I would lean more towards wondering if they did it at all.

I think they did the flash because it shifts differently than it did before. It seems when you are coasting down to a stop the engine isn't breaking the Jeep as much as it used to. Before when I would coast down you could feel the engine slowing the Jeep down. And the bump down from 2 to 1 when it downshifts is not as noticeable.
