I know the whole 6th gen V6's had only a automatic, however, like kenton said, someone told me he knew a girl who had a 6th gen V6 5speed. and He said it was a rare factory option as well, so maybe there are a few floating around, I doubt it, but maybe, lol. As far as Av6 swaps go, its possibled to swap over the CL-S 6 speed with little modification, its been done, however, espeically if your supercharged, you might break your front motor mount alot until you custom make a poly-urethane one.
