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.
