First question would be if the oils in the 2 transmissions were changes at the same time? If they're vastly different hours on the two, that could be part of the difference. Copper I believe can also be clutch plate wear. The lead would be a concern as I believe that's relative to bearings. Sodium is also one to watch as a significantly elevated level can indicate a transmission cooler going bad (Sodium as in salt from saltwater).

For oil analysis to be more helpful, you need to see a number of tests over time (trends) with known intervals and oil changes.

I would change all oils to establish a baseline and reanalysis the transmissions after 100 or 200 hours. Personally I prefer Blackstone for oil analysis as it's easier to compare multiple samples of the same engine or transmission. Also, they're very receptive to calls about their testing if you have concerns.

I'm tired of fast moves, I've got a slow groove, on my mind.....
