Allison specifies the first service change at about 5,000 miles, after which routine replacement helps maintain oil cleanliness and system performance. The combination of filter media and magnet provides both particulate capture and a secondary defense against metallic contaminants commonly introduced during break-in and regular operation.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this spin-on filter fit and install on Allison 1000\/2000 transmissions?\u003c\/h3\u003e\n\u003cp\u003eThe Allison 29539579 filter is an external spin-on design made to thread onto the factory filter housing on compatible Allison 1000 and 2000 transmissions. Installation is straightforward and follows typical spin-on service procedures: drain or relieve pressure, unthread the old filter, lubricate the new gasket, and tighten to the specified torque.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDirect replacement for Allison external filter housing—no modifications needed.\u003c\/li\u003e\n  \u003cli\u003eThreaded spin-on makes for quick swap during scheduled maintenance.\u003c\/li\u003e\n  \u003cli\u003eIncludes magnet 29535617 to install in the filter assembly per Allison guidance.\u003c\/li\u003e\n  \u003cli\u003eFollow Allison torque and seating recommendations to avoid leaks.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhy is the transmission magnet included, and when should it be changed?\u003c\/h3\u003e\n\u003cp\u003eThe magnet 29535617 is provided because Allison requires replacing the magnet with the filter to ensure metallic particles captured in the magnet are removed from the system. Over time, the magnet collects ferrous wear debris that, if left in place, could reduce effectiveness or reintroduce particles into the fluid stream during service.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMagnet removes small ferrous particles that bypass the filter media.\u003c\/li\u003e\n  \u003cli\u003eReplace magnet at every filter change to maintain collection efficiency.\u003c\/li\u003e\n  \u003cli\u003eIncluded magnet fits the filter assembly and is sized for Allison 1000\/2000 units.\u003c\/li\u003e\n  \u003cli\u003eSimple install—clean seating area and press magnet into the designated cavity.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat service intervals and recommendations apply to this Allison filter kit?\u003c\/h3\u003e\n\u003cp\u003eAllison recommends the first replacement of this spin-on filter at roughly 5,000 miles to clear break-in debris, with subsequent intervals determined by vehicle use and Allison service schedules.
