My 65 with a 3 speed manual tranny only goes into 1st gear when I am at almost a dead stop. If you are rolling at any speed at all, it will grind when dropping down from 2nd. I've never had a tranny that wasn't synchronized, is this what I'm dealing with? Didn't really think at this late date they were still making them that way. I've learned to deal with it this way, but it is annoying at times.
