Here's a ZF 8 speed UOA that I just pulled off the JL Wrangler forum:It died after he put fluid in the thing that isn't certified for the transmission. There's a whole lot of unknown here but the things we do know are that they used the wrong fluid and the transmission failed.
The "critical" lab results OP posted are here. 906 ppm iron, 662 ppm copper, and trace amounts of glycol which typically means we measured it but it was insignificant. That's what all this is about and for literal wear metals in every transmission, those numbers are a complete joke.
112ppm iron and 39ppm copper at 50,000mi on a healthy transmission. Kinda seems like the lab got it right and you are making baseless claims here.
