Hey Larry, good to hear from you. The transmission works great. I sent it to a company (Novak) back in the midwest that specializes in rebuilding the old SM 420's and had it completely gone through. Cost me $600 w/o freight, that was another $140. Had the 235 that you found for me completely rebuilt as well. If my memory is correct, it was about four years ago I stopped by. I purchased the truck five years ago last month. Yup, took me five years to complete. Ring and pinion are on my radar screen probably later this year. I do enjoy driving it the way it is, by I am concerned when driving on the highway that I might wind it to tight. 45-50 is top speed. Next time time you are in Montana stop by.
