For those of you who may be curious about Makco Distributing aka Bulkpart.com aka Makcotransmissionparts.com, I think they were legit.
The solenoid shipping was a bit high (~$12 for a ~$40 product) but I ordered it on 3/4 and it arrived on 3/10 (AL to CA in 6 days -- not bad).
It came in a baggie and a box and seems to have a thin coat of ATF on it. If this was a used product, they went through a heck of a lot of trouble to make it look legit.
I won't know for another few weeks if what i received was 100% good as I need to schedule time with my other team members to work on this birds tranny. I would tentatively recommend this outfit though....
