Dropped the pan on the transmission in my 93 W250, no huge amount of deposits noted but the magnet at the bottom of the pan is loaded with small particles that kinda look fuzzy once disturbed. Yeah, I know it's because the particles are so small and obviously magnetically permeable, I'm just unsure if the amount is normal or not. The truck has ~ 120K on it, lots of use with a snowplow, so mild abuse at least; to my knowledge the trans has not been opened up before but don't know for sure. Trans is a 42RH/A518. Dropped the pan for a look-see since it's been whining very loudly and getting worse - sounded exactly like a hydraulic pump with no fluid to pump, so I was thinking possible clogged filter. Filter doesn't look great, but not as bad as I was expecting.
Thanks,
Mike
