Just curious as to how you like the new tranny. I need a new one for my car, and the TKO's seem like a good price, $1500 for the 500, $1600 for the 600. What problems have you had with your tranny so far if any? Would the extra $100 be worth upgrading to the TKO 600? I would have done a search, but they came out not to long ago so I figure I wouldnt find much info about them after being used some.
