Not necessarily. Those other parts could all be on an urgent rush status too, going to other dealers across the country. It could be that was the fastest way to get your part on a shipment here.*Update*
I called the dealer today and they said the hydrostatic unit landed at JFK. BUT, now it has to go through customs (1-2weeks), then be shipped to Texas and inspected then to the dealer. It is with a bunch of other parts so their is no way of finding the package as I live 1.5 hrs from JFK and was going to try and get it. The fact that it's with other parts means that it was no special rush and basically nobody gives a crap when it will get here.
