It's been both ways verbally. Without being there, or looking up the laws (which don't apply to me, so you know how far that's going to go... ) I can't say one way or the other for sure.

I do know that there is very little that is legal according to the EPA when it comes to engine swapping. I posted a PDF of the abstract somewhere, either here or on CustomTacos.com.
Hmmmm, I guess I was lucky because they never used the 5th gear that I swapped. In 2007 when I passed, I didn't have the 5th gear, but they only went as high as 3rd gear in their test. In 2009, they only went as high as 2nd gear.

But even if they had an issue, my gear swap would have complied with your statement. But it's a good thing I didn't swap the whole tranny, because I didn't have to deal with it.
