Brass looking metal in ATF

[Lockasiam]

Dumped the atf out of the old 41TE yesterday, and other than a fully loaded magnet (singular when I think there’s supposed to be 2) there was some brass looking metal in the drain pan. Where would brass even come from in an A/T? Judging on the gouge in the mating surface and the missing magnet I’d say some idiot dealer did the 100k service so there was likely about 150k on this atf

Are you sure it's not discolored steel flakes? Check and see if a magnet attracts these particles.

They weren’t on the pan magnet so I’d assume non ferrous

Bushings & Thrust Washers have Brass/Bronze in them.

So at 250k and assumed 150k on the fluid I shouldn’t be overly concerned since it still shifts fine?

I wouldn't, But lets be honest.....No one is going to have the unit gone through to make sure (Outside of competitive motorsports)

It’ll get gone through when it fails and gets rebuilt

Just intrigued where all this brass came from, probably some aluminum too
