Double-deep spin-on filter with 2.72x more media that traps to 15 microns for the Allison 1000/2000 behind the 6.6L Duramax; replaces GM 29539579.
The external spin-on filter is the part of an Allison 1000 service that Duramax owners change most often, and the stock can is short. This is PPE part number 128059150, a double-deep spin-on that threads onto the same filter boss as the factory filter but carries 2.72 times the filter media inside a taller can and is rated to trap particles down to 15 microns. It is built for 2001-2019 Chevrolet Silverado and GMC Sierra 2500HD and 3500HD trucks with the Allison 1000 or 2000 Series, and for Kodiak and TopKick medium-duty trucks, and it replaces GM 29539579 and 12471607.
The Allison has two filters. The internal filter in the pan is a coarse screen ahead of the pump. The spin-on is the fine filter on the control main circuit, the pressurized oil that feeds the shift solenoids, the trim valves and the clutch apply circuits. Those valves run with tight clearances, and fine wear metal and friction dust are what make them stick and cause flares and harsh shifts. Allison puts this filter on a shorter interval than the fluid: 50,000 miles, 2,000 hours or 24 months in general service, even when the fluid itself is good for much longer. More media area means the filter takes longer to load up and keeps flowing freely toward the end of that interval, which matters most on trucks that tow heavy and run hot.
A filter will not fix a mechanical failure, so look before you buy. Check the fluid hot for color and smell, and when the old filter comes off, clean the magnet and look at what is on it. Allison says to report any metal pieces larger than dust. Fine gray paste is normal wear; flakes or chunks mean something inside is coming apart. If the truck has shift complaints with codes stored, start with our Allison 1000 valve body testing guide, and use the fluid and filter service guide for intervals and capacities.
Listed for 2001-2019 Allison 1000 and 2000 Series transmissions: Silverado and Sierra 2500HD and 3500HD with the 6.6L Duramax, plus Kodiak and TopKick. It replaces GM 29539579 and 12471607 with no adapter. Two honest notes before you order. First, the taller can needs room; on most pickups it clears, but lifted trucks, skid plates and aftermarket crossmembers can get in the way, so measure the space below your filter boss. Second, Allison specifies 29539579 for trucks with Prognostics turned on, because the Filter Life Monitor in the TCM is calibrated around that filter. If your truck uses the monitor, you may prefer the factory part. Not sure what you have? Send us the year and VIN. The full Allison parts collection has every filter option we carry.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. It replaces GM 29539579 and 12471607 and threads onto the same filter port with no adapter. The can is taller, so check clearance on lifted trucks or trucks with skid plates.
It is listed for 2001-2019 Allison 1000 and 2000 Series trucks, which covers both the five-speed and six-speed Duramax years. Send us your VIN if you want it checked.
Hand-tight to gasket contact, then one full turn, which is Allison's instruction for the spin-on filter. Over-tightening can damage the filter and makes it hard to remove next time.
Yes. The double-deep can holds about half a quart more than the stock filter. Top off after the swap and set the final level with a hot check in Neutral at idle on level ground.
No filter resets the monitor by itself. If your truck has Allison Prognostics enabled, the Filter Life Monitor is calibrated around the 29539579 filter, so some owners stay with the factory part on those trucks.
