Try car-parts.com. I got mine for $500.00 with only 9K miles on an automatic. I also got the higher stall converter from protorque. I will say it does pick up better. I'm impressed. They also included shipping in that price so good luck.
what if a get a new torque converter? I replaced mione already, but can i get a performance one? cause i dont wanna blow my auto tranny racing, already replaced it once!
