[Dean S.]

I have a metal tag attached from my transmission with the number 857580? What code is this?

Mine has the same tag and it's a wide ratio M20.

Missing the first digit "3", probably hidden by the bolt on the side cover.

It's the GM part number for the transmission assembly. You'll want to keep that tag.
