Does anyone know what toyota does exactly in the Transmission flush service? I know i could do it myself but with the cylinder 5,6 misfire I had with new toyota spark plugs my dad just wants me to do it at the dealer

Sealed Transmission and it has a very specific way it is to be done. It has to be measured at a very specific temperature.
So, from someone who always did that before; I let them handle it. They don't do a flush per say, they do a fluid exchange. At least, that was what I had done. Not sure if they offer a flush. The different words may be semantic to some, but one applies external pressure (flush) while the other operates at the Transmissions native pressure (exchange). 99 times out of a hundred, a flush will be fine; but every now and then the external added pressure can clunk something up.
Anyway. I had my sealed 5 speed fluid exchanged by a dealer almost 5 months ago and I report all is well. My transmission didn't have any issues before, so I wasn't looking for some cure. I just knew that at 110k miles, it needed to be done.
The rule of thumb from them is 100k. Toyota considers the WS lifetime fluid... and they did actually say my fluid looked dark, but still fine. Whatever it is, it is hefty stuff. I just felt that putting new in was a smart choice.
Anyway. A fluid exchange will essentially have them replace your old with new, ALL of it.

Spot on. The machines we use use the transmission line pressure to let the old fluid push out the new fluid at it's own pressure. We don't use the electric pumps to make it go quicker.
If you actually brake it down by parts and labor, the newer WS sealed transmissions will run you more money because the fluid at retail price is around $10-14 whereas the Type T-IV ('03 and older) is much cheaper. 12-16qts can get expensive in parts alone.

so glad i have the 03 without sealed system 
.. but x2 on taking yours to a dealer for there machine flush service... if you have serval dealer options call there different service techs and get the best price sometimes dealers run specials on fluid changes and what not. or sometimes you can say well toyota of so in so priced me this and they'll drop the price a little for you.
