So some guy over on a volvo forum, known as turbobricks, has created a transmission controller to take the place of the PNP switch on the Volvo AW30 transmission which allows him to use the paddle he made. The part where this is interesting for you guys is that this tranmission is the same one that was used in SC400s and LS400s. check this out, post ur comments or if you have tried/done somethin like this already.
