Just pulled it today anyway for our engine rebuild. It’s on a stand so dropping the pan is easy; no go on the line pressure test.
Ok, I would have done the pressure test but your call...Bring it back to the builder, advise of the symptoms you were experiencing in 3rd gear...Ask him if he drilled a supplemental bleed hole in the direct drum...For very high HP/RPM applications, I always drill a .055 bleed hole just below the piston's outer lip seal surface at the bottom of the drum to prevent centrifugal apply/clutch drag at 6000+ RPMs when shifting from 1st to 2nd. If he did drill the hole, it may have been drilled to an excessive size (i.e. .070+) or interefered w/the lip seal and partially cut the seal...Just a theory, which won't apply at all if he didn't drill the bleed hole.
