The flywheel on my 2006 Galant (2.4 engine) needs replaced due to damaged teeth. My mechanic tells me that the flywheel is attached to the torque converter and I would have to replace that. But I find on used car part sites a lot of matches for a flywheel/flexplate for this model, but no matches for a torque converter. Can anybody tell me if I need to buy a used/rebuilt torque converter or can I just replace the flywheel/flexplate. If I need to replace the torque converter, where can I find a cheap used or rebuilt one?

Thanks
