Automatic trans flash update.
I had my truck in the other day for the rear differential cover replacement recall.
While it was in there, they flashed the radio for the Sirrus traffic fix, and also flashed the transmission for the "driveability" issue...
The transmission is definitely different. It holds gears longer, and shifts "softer."
The "vibration" (for lack of a better word) is almost non existent now. I have not felt it since the flash. I think the new shift pattern helps keep the engine from laboring in MDS.
The tech doing the repair didn't like the fit of the leather steering wheel cover, so they ordered a new steering wheel - to be installed tomorrow morning.
The service manager commented on how nice my Bakflip, F-1, was, and said, rumor has it that Bakflip is soon to start making bed covers for Dodge.
I notice NO difference in mileage, but it sure drives nicer.
NEXT DAY:
Here's something else I noticed this morning - it seems to change much more quickly from MDS (4 cyl to 8.) Which helped eliminate the vibration associated with laboring in the 4 cyl mode.
I also feel that shifting upwards, in normal use, is not as invisible as it used to be. Probably due to the fact that it stays in gear longer (until there is no load), and shifts "softer" to the next higher gear.
Overall, it's pretty much done away with the problem, and I like it much better.
I think this might negatively affect mileage, in around town driving - as it does not stay in MDS as much as it used to. I used to see a lot of 30+ MPG on the bar graph, and it now seems to hang more in the 28-29 range.
Time will be the ultimate proof, as I am used to 14+ around town at fillup time.

We are referring to AVERAGE MPG. Over the course of a tank of fuel or at certain speeds in varying conditions etc. What does you AVERAGE for interstate driving over 30 miles this say for example?

I was referring to instantaneous readings while in ECO, at about 35-45 MPH cruising.
In normal in town driving, usually around 14.0 -14.3. Calculated, over 200 miles.
All highway, between 55-65, usually average 20.8 - 23.0 - as high as 28.0 on one fillup.( 250 mile run between 45-55, on very rural highway.) All calculated at over 200 mile runs
