As I understand it, the issue isn't that meeting emissions is any more or less difficult with a manual vs. an automatic--it's that once they've done all the work for the automatic, they need to go and do a bunch more work for the manual. I've been to some of the facilities where the "offical" emissions certifications are done, and they are huge and expensive (multiple millions of dollars for all the equiptment), plus a crew of technical support people. I remember hearing that it cost multiple thousands of dollars per hour of testing time to go into one of those facilities. Even if they didn't have to change a thing about the tuning of the engine, I wonder what the cost would be just to test it and certify it.
