Im thinking about puchasing the shift solenoids for band 2-5 and having them installed. But my main question is ford tech says they have to reflash the computer for new settings in the trans. Is this something that my tuner can do for me?
I wouldn't touch it unless your having problems or I will do it myself.
You can NOT purchase the solenoids until after you examine the stock ones in the tranny. The band refers to a number on the solenoid itself. I just performed one, and there were two band 4 and one band 5 solenoids.
Here is a pic showing one of the solenoids and the band number. It is a number 4 solenoid. You have to hold the solenoid at just the right angle in just the right light to be able to read the number clearly.

I'm with you, mine doesnt flare or do anything weird like the TSB says so I'm not messing with it. Sometimes its best not to fix what isnt broke
I get a harsh shift, especially at low RPM going into the upper gears, like cruising through town at 25MPH. Even after having my tuner adjust the trans tune.
Also, at the track and on drag radials, my 1-2 shift is quirky. It acts like the trans is losing pressure on the shift. It feels like the gear selector gets bumped into N, just at the shift. The RPM will go right to the limiter and the car noses over. I have to let off the gas completely to get the car to shift. If you get off and get back on it, the car drops RPM and then revs right back up, just as if it went into N.
The solenoids are not expensive, in fact, the trans fluid will wind up costing more. So I can't see a downside to changing them.
Oh BTW, I have a June '10 car, so if my dealer wasn't totally useless, I would fall under the TSB...
Negative George.
There is a large plastic piece that is bolted to the top of the valve body, so the valve body has to come out just to get that off.
