Mine was flashed and it has been smooth sailing. Before the flash, not only did the car slam into first, but it seemed like when I was accelerating from a stand still, that first gear would feel particularly week, and then when then car would shift into second, the power would come on. It was very strange. Since the flash, power has been much more linear and first to second has been MUCH improved.
Which Dealership in NY you went to flash it? The glen cove, LI dealer tells me all the tranny software is up to date and theres nothing he can do. I still get problem of the jerkyness and im hoping that they just didnt know what they were doing

TSB not issue
So for those feeling the need for speed... it's gonna cost ya. Also, we say we're not changing our driving habits, but subconsciously with a more "brisk" engine, we do change our driving habits.
Anyway, I'm getting a really big split of 27/19, so we'll see how this TSB does for me. Keep you all updated ...

Just got it done... NIGHT and DAY is the difference. Just pulling out and turning right from the dealership I could feel it more responsive. Where it use to hesitate just slightly to want to move, now it zips off. Not Corvette fast, but much faster without the hesitation.
The reprogramming was covered some federal EPA emissions thing, so it was N/C for me. I went in for a headlight adjustment too and it was N/C. I've been going to this dealer with my RX since we got it, so I guess keeping a relationship/history with a dealership does help for minor items/adjustments like this.
I will have to see if my mpg drop because of this programming. The service writer did have a "are you sure you want to do this..." question. Concern is that once the TSB is done, it's done. You can't go back to the old settings because they're setting new shift points through the whole 6 speeds, not just the lower gears. I asked what are the drawbacks? He said that it COULD shift harder and some drivers feel a rougher downshift. I told him, beats having what I conside a "dangerous" situation where the car hesitates when you don't want it to.
Anyway, it shifts fine for me. No rough up or down the gears. I'm very satisfied, thus far. If my mpg falls to 14 mpg, then I might have to reconsider my decision...
