Pat, You're a little far away, otherwise i'd offer you mine. The sm420 is a good truck transmission. It is a very noisy one, but i found that they (or maybe it was just mine) shifted very well, like a truck transmission should.

First gear is pretty much useless unless you are pulling tree stumps out of the grounds, literally. Final gear (fourth) is a 1:1 ratio, which is why i went to a different route for overdrive.

honestly, I think $300 is rather high for one of these. I've seen them sell up here for between 75-150. That said, they say they are working transmissions, but no one really knows until you expect it.
