There was a small layer on the bottom of the pan and I could see some floating in the oil in the converter. This trans is mounted behind a 400hp motor. Is this normal after a new rebuild? Do you recommend any action before reinstalling into car? Thanks.

sibon3,
Typically you will see that after a fresh rebuild. What you need to be worried about is chunks of aluminum or larger chunks of friction material.

Thanks
