On our last towing trip I noticed a SLIGHT bit of trans noise that I had not heard before. Today I drained the transmission, I have dual coolers on the PTO covers and a filter on the left side. In that filter I hung a high power magnet. When I removed the cover for the magnet it looked kind of like a porcupine, all bristly with metal filings. Not any of them large just very fine stuff. I am going to pull the trans and send it away to be rebuilt. Is Standard in Texas still the place to have a top notch job done?
