I really need someone's help on identifying this 4t45-E transmission part and where I might be able to find a new one. I was replacing the solenoids in my transmission by taking off the side cover and I got them all switched out. I was tightening the side cover bolts down and I heard a pop that sounded like something hit the side cover and when I went to check the axle seal I seen this (I have attached the picture). I have no idea where this came from. I seen this video on YouTube: https://youtu.be/2WzF1q3hZHs and it looks like the part he takes off at 8:39, but he doesn't talk much about it (I thought he called it a latch); also the transmission worked on was a 4t40-E It looks like a spring to me. Any help would be appreciated. Thanks.

The picture didn't post so I'm going to try to attach it here: Your text to link here...

Also it is from a 2008 Chevy HHR LT 2.2L

[SOLVED] - It was just a spring that was in the seal that got pushed out when I put the cover back on.
