Guys i just found this and was wondering if this works like i think it does http://www.takakaira.com/php/template.php3?id=185&cat=2

so it requires a Manual tranny right? whats the plus and minus? would this be a good idea?

Don't get me wrong, it's very innovative, but I don't think it would provide a performance increase. It seems like an add on for someone who wanted an auto. in the first place. $1600 is a lot of money.
