Convertors are a haven for all types of contamination when a trans dies....
Flipping it and letting it drain will do zero to remove these contaminants....
The lockup clutch face surface cannot be checked for damage....
The internal components cannot be checked for damage...
The contamination residue including metal dust and clutch dust cannot be removed...
The burnt oil on the ground would most likely be a direct oil dump from the convertor....
Sorry to say this but IMHO...pull the trans, send the convertor out to be split and overhauled...do not accept having it flushed...
Then pull the trans back down..It will need to be fully dismantled and everything cleaned up, resealed and reassembled...
Change the sprag out to a BW late style...
As a heads up, there are several write ups on our forums especially detailed ones by "clinebarger"...who in my mind is the best trans guy I have ever seen....he does it right first time for a reason...its the right thing to do...
Hope this hasnt been to harsh a response....there is no easy fix for this...
