Two converters is unusual, no? Maybe unique? i went looking to confirm and see what the costs are. Seems the second converter is quite cheap. Here is a parts diagram and list:

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
