how do i tell the dealer "do not reflash.." ?

[ballisticmike]

I noticed a slow oil drip from the transfer casing today. So i scheduled to bring truck into dealer on monday where it should be a routine warranty repair. I dont know why its dripping and there is no performance changes noted in driving. Sunday i will reset truck back to stock and remove the lovely gryphon and cable.

so..
1. for a repair of this nature, is it unlikely they will need to reflash my truck?
2. if they say they do need to.. how can i say "no" to that ? -
A). if they need to reflash then they need to reflash, right?
B). saying "do not reflash" is the same as saying "I have an aftermarket programmer".
3. is it possible they will see the code that tells them a programmer was present, and then on that basis deny warranty service by trying to blame everything on the programmer?
