where can i get a new torque converter for my '95 import wrx wagon? im pretty certain its playing up, especially at motorway speeds. the kick downs seem a little sketchy, and often when at half throttle at 70mph it just judders around a bit gaining speed quite slowly. i'm sure its not coil packs or maf, it feels more mechanical, and the symptons match that of a dodgy torque converter (from what i can gather).

any help would be cool, cheeers
