    SM420 transmission. $100, prefer not to ship.
    IMG_1450.jpg IMG_1451.jpg IMG_1452.jpg IMG_1453.jpg This is an Early SM420 as defined by Novak with the oil weep hole on the input bearing retainer and the earlier 3-4 shift collar. I bought this to use the top cover, so a new one will need to be sourced if you want to use the trans. I don't know how long it has been sitting, nor do I know when it was last used the internals look good, and it shifted alright on the bench. Note that I did drop a bolt in it, but I think it is stuck on the drain plug and I couldn't fish it out in my 2 minutes of trying with a magnet. It shouldn't be a problem, one just needs to pull the drain plug.


    NOS Gama Goat cable-shift top cover. $100

    This came on my NOS ConDiesel SM420 trans. I had Novak swap one of the shift forks into a normal top cover for my use, so one of the forks is not NOS. The 3-4 shift fork is now the earlier 5914985 part, so this top cover should work with the earlier SM420s.

    All prices are OBO, all shipping is on buyer's dime
