Allison External Spin-On Transmission Filter Kit 29539579 with Magnet 29535617 for 1000/2000, Genuine Easy-Install

Allison 29539579 is a genuine spin-on external transmission oil filter sold with the matching Allison transmission magnet 29535617 for Allison 1000/2000 gearboxes.

This kit pairs the authentic Allison external spin-on filter with the required transmission magnet to retain ferrous debris and prolong component life inside Allison 1000 and 2000 model transmissions. 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.

How does this spin-on filter fit and install on Allison 1000/2000 transmissions?

The 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.

• Direct replacement for Allison external filter housing—no modifications needed.
• Threaded spin-on makes for quick swap during scheduled maintenance.
• Includes magnet 29535617 to install in the filter assembly per Allison guidance.
• Follow Allison torque and seating recommendations to avoid leaks.

Why is the transmission magnet included, and when should it be changed?

The 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.

• Magnet removes small ferrous particles that bypass the filter media.
• Replace magnet at every filter change to maintain collection efficiency.
• Included magnet fits the filter assembly and is sized for Allison 1000/2000 units.
• Simple install—clean seating area and press magnet into the designated cavity.

What service intervals and recommendations apply to this Allison filter kit?

Allison 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. Regular inspection and fluid analysis under heavy duty or severe conditions will guide more frequent changes if needed.

• First filter change at about 5,000 miles as recommended by Allison.
• After initial service, follow manufacturer intervals or fleet maintenance plan.
• Consider more frequent changes for towing, heavy loads, or harsh environments.
• Inspect magnet each service for metal accumulation and replace with filter.

Will this genuine Allison part affect warranty or system compatibility?

Using genuine Allison parts like filter 29539579 and magnet 29535617 supports OEM compatibility and aligns with Allison service practices, reducing risk of fitment issues. These parts are manufactured to Allison specifications to preserve component interfaces and fluid flow characteristics.

• OEM parts match Allison tolerances and filter media performance.
• Using genuine components simplifies warranty and service documentation.
• Designed specifically for Allison 1000 and 2000 transmission families.
• Purchase includes the magnet required by Allison for each filter change.

Who is this for: technicians, fleet managers, and vehicle owners operating Allison 1000 or 2000 transmissions who want a factory-recommended spin-on external oil filter with the matching transmission magnet. This genuine Allison kit is suited for routine maintenance, initial break-in service, and any repair where original-equipment fit and filtration performance are required.
