The symptom that first made me question that there might be a problem was that I began to notice that my car would not upshift when I would pull on the upshift paddle. Downshifts were fine. At first I noticed that, it would upshift, but irregularly. Sometimes it would upshift, then other times it took several tries on the shifter paddle to get the shift to occur. (Reminded me of bad contacts on an electric window switch). I found that if I used the center console gear selector to manually shift the car, the upshifts were precise and immediate, as you would normally expect.
The problem was easily fixed. The dealer ordered a new set of paddles and switches and the replacement only took a couple of minutes. By the way, it turned out that both switches were failing. Both had cracks running across the area where the screw draws the switch assembly into the steering wheel.

Check your gear selector lever position indicator for the gear range that appears in the odometer desplay. When downshifting, the gear change indicator number should be immediate. If the indicator isn't immediate then your downshift paddle isn't working correctly. If your downshifts are slow, your transmission ecu isn't getting the signal to downshift or it doesn't want to do something stupid like going from 100mph into 2nd gear.

Did the updated kit fix the problem permenantly? Did the problem ever return?
If we could just get that damn Speedshift Plus software....
You did say TCU, my mistake.
Any possibility of that flash happening?
