Rebuild or run it?

[JNJchev77]

While changing the servo to a Corvette Servo in my 4l65e, my Trans pan showed up, so I decided to pull the pan and check it out, and put the new pan on... Well when I pulled the old pan this is what I find... I was told the trans had about 45K on it....


My knowledge of Transmissions is very, very limited lol. Question is, is this the thing ok to run? Or should I have it rebuilt? The square ribbed looking piece is a magnet that was near the drain plug, is this standard, or has this pan been off before?

I am just running basically a mild 5.3, driver, nothing crazy.
