I recently accomplished my transmission filter change, when I pulled it, I cut open the filters to see if there was metal and I found a bit, most metal was ferrous flakes smaller less than .002, some brass shaving about .0025x.125” and longer ferrous shaving about .0020x.25”. This was the filter change at 2000miles at 36 month per Allison recommendation for normal duty running on a TES-295 fluid.
When I first got the truck from auction I replaced the filters and did not find any metal.
I was wanting to find out what other people have found. The trucks has about 8.2K on the odometer, but ECM data shows about 12k.
I could not find an Allison transmission resource in filter inspections for a high material count, based on my experience with aircraft maintenance and hobby automotive work this would be a moderate to high level of metal contamination.
Ref attached pictures, the washer is about a quarter’s size. I could not find a quarter or change prob because I spent it all on my truck.
Thank for your input.
