I'd go $250 for the trans, and I don't ship freight, because it's too much hassle, and the item ALWAYS arrives damaged, we don't have a freight depot close enough to us to make it worth my while, I don't have any skids laying around, nor the time to build one.
Instead, I have a truck...We have been known to drive parts halfway across the country for a customer....I delivered a hardtop to Las Vegas 2 years ago for a customer (I'm north of Chicago)....
Would I deliver a trans? Maybe. Depends on what other loads I can find for the trip.
