tough question
Is it possible to tell if your truck has a shift kit installed without pulling the pan?
I bought a used 2003 and was told the trans had been rebuilt. I have since contacted the dealer I bought it from but they were unable to tell me anything about the rebuild. The truck makes really solid shifts in my opinion but I have nothing to compare it to. How firm do these tranny's shift in stock form? I'm planning to order a PHP chip soon but am afraid if it does have a shift kit the new tuning could make the shifting overly harsh. Anyone have any ideas?

Seems like alot of the tranny guys I know like to add a tugger kit (or similar) to their re-builds, mainly from longevity. But the way I understood it, the dealer just installs a rebuilt unit and sends the original back as a core. If this is the case - it would be hard to believe the re-man OEM trans would have any modified shifting components.
If you are satisfied with the shift firmness/feel as it is now, have PHP leave the shifting parameters stock.

I specified that I have a shift kit when I ordered my reburn. Not sure if shift points were still programmed in or not...but shifting is still fine as it is now.

Yea, what Cody said. I wouldn't worry about it IMO.

I don't have enough experience with these trucks to say whether the shifting is good or not. It definitely shifts harder than my '99 Chevy 1/2 ton but I would expect that.
On upshifts it feels like shifts are made with the torque converter locked up. They're not harsh but my butt can feel each shift. Almost like I had a subwoofer behind the seat. Is that normal? One of the reasons I want custom tunes is to improve the tranny life with the towing I do. I'd hate miss out because I didn't know any better.
