I have a 2006 Honda Civic that I purchased with a blown head gasket, being that it was higher mileage car I replaced it with a used low mileage engine. The torque converter was still attached to the used engine so I used it instead of my old one. Now, after reaching operating temperature it starts to make a chirping / squeaking noise from the flexplate/ TC area. Car shifts fine though and doesn't make noise til engine is warm. Since it doesn't do it all the time I don't think it can be anything rubbing , right? I've checked all the TC bolts and fluid level.
I pulled transmission back out to check for cracked flexplate, but looked fine. Now I'm not sure what needs to be replaced.
Here is a video of the noise:
