turbo 400 debre

[altune]

I dropped the pan on our trbo 400 and found some black sooty looking debreis. It has been in service for a while and am wondering if this is normal. the magnet had some residual filings, very small on it.
Who make a good trans kit to rebuild this deal?

redline is more for racing but trans tech also makes some good kits for street strip.
