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 rather than tearing it down. 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 this noise til engine is warm. Since it doesnt 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.

Some people had told me possibly cracked flexplate so last night I pulled the tranny out, no cracks.


Here is a link to the noise:

Any help greatly appreciated.

 

You should've used your original torque converter, but is there a little dustplate down there? If so, I'd check to make sure that thing isn't bent and touching the flexplate or torque converter mounting bolts.
