Pulled my transmission to replace the rear main seal. While I’m at it, I’m trying to diagnose a chirping from the bellhousing area. Pulled the flexplate and laid it on a flat service and noticed it has the slightest bit of warp to it. If I push down on one side, you can slide a piece of paper or two under the other side. Tried it on 3 different flat surfaces to make sure. I have another flexplate that was new in the box that I opened and tried the same thing and it did the same thing, so I’m thinking it’s normal? Other thoughts?
