Hi guys, I was changing the rear transmission seal and I found this just sitting on the output shaft. I tore the old seal up pretty bad trying to get it out, I'm hoping it's part of that, but I didn't notice anything that looked like it on the new seal. Can anyone tell me what this is before I go busting up my transmission?

 

It's the spring off of the old seal, no harm.

 

That's what I thought, wanted to be sure though before I tried to drive around and had something pop loose.

Thanks much!
