Picture this: you're hauling a heavy load down a long interstate, and your Allison transmission shifts without a hitch. That's the peace of mind this genuine spin-on external filter (part 29539579) and magnet (29535617) deliver. No guesswork—just reliable performance from the folks who build these transmissions.
Transmissions take a beating from heat, debris, and metal shavings that build up fast in Allison 1000 and 2000 series units. Skip the filter change, and you're inviting sluggish shifts, overheating, or worse—a full rebuild that costs thousands. Allison themselves say swap this external filter after just 5,000 miles on new installs to catch the grit before it circulates.
This kit is OEM genuine, so it fits perfectly and filters better than generics. The spin-on design means no mess—just twist off the old, stick the magnet in the pan to snag stray metal, and spin on the new one. We've seen it extend fluid life and keep gears meshing quietly mile after mile.
Truckers swear by it for cross-country hauls where downtime isn't an option. RV owners love how it prevents those embarrassing lurching shifts on hills. Even fleet managers stock up because it cuts repair calls. Feel the difference in crisp acceleration and cooler running temps—your wallet and schedule will thank you.
Don't wait for a warning light. This filter and magnet combo is the smart maintenance move for anyone serious about their Allison-equipped ride. Order now and hit the road with confidence.
