<strong>Yahoo Message Number: 107527</strong>I have a friend who needs to change the spin on filter for his driveline hydraulics. This is a 2006 Magna with a Cummins 600 ISX. This is not the reservoir with the internal filters, this is mounted externally next to the tank. The original label is long gone. I would also guess it takes Dexron 3?? A substitute would be Dexron 4?? Thank...
