Normally I'd agree, but solenoids control up/down shifts, not initial engagement. That's all hydraulic. Delayed engagement points to loss of fluid pressure, clutchpacks not applying until sufficient pressure builds. Coupled with whining or howling when not in gear and lack of upshift with slippage (shift initiates, but all the hydro pressure is expended before the next range can be applied) points to a huge hydro blow-off somewhere internally or lack of pressure from the pump to begin with...
When solenoids go bad they engage from park or neutral, but fail to upshift and just hang in the range they get stuck in, but don't fall out of engagement and slip...
Raising the idle and getting a faster engagement doesn't totally confirm it, but does suggest that a lack of fluid pressure is the culprit...the causes can be many, but pump failure is common with the noise you describe...
Still should be checked by a tranny pro...could be something common to Honda trannies that I'm not familiar with.
A shop can check fluid pressure at service ports and tell if the pump is shot or if there's a restriction or internal seal hemorrhage that's causing the problem.
I guess you haven't felt out Honda about a warranty on the replacement unit?
