So... I'm fairly certain that the torque converter has taken a dump in my WJ. I was searching online, and couldn't really find any. Where do you guys shop for transmission parts? Torque converters in particular.

Best bet may be local Craigs list and/or Recycle yard. You can pick up a used trans for fairly cheap.

I got a used trans with 40k miles and a 30 day waranty for $700 after taxes. Had it installed in under 4 hours with help from a freind's dad.
