Genuine Allison Spin-On Filter

This is a genuine Allison spin-on filter for the Allison 1000 5-speed and 6-speed automatic transmission that back the 6.6L V8 Duramax Diesel and 8.1L V8 gas engines in 2001 through 2019 GM 2500HD and 3500 trucks.

For healthy transmission life we recommend replacing the spin-in filter every 12,000 miles. Be sure to clean and reuse the filter magnet sandwiched between the spin on filter and the transmission. In many instances it the magnet sticks to the filter and can accidentally be discarded along with the old filter. Replace the magnet with a new one if you cannot locate your magnet.

NOTE: Also fits Allison 2000 model transmissions.


What is the recommended replacement interval for the spin-on Allison filter?

Here at Merchant Automotive we recommend replacing the spin-on filter on your Allison transmission every 12,000 miles for the best transmission health and longevity.

I accidentally threw away my filter magnet. Do you sell them separately?

Don't worry, it is a common mistake, and we have the magnets available click here to see the listing.



My transmission did not have a magnet when I removed the spin-on filter. Do I need one?


Yes. All Allison 1000 and Allison 2000 transmissions were originally equipped with a magnet between the spin-on filter and the transmission from the factory. Even seasoned mechanics sometimes slip and discard the magnet with the filter. If your transmission is missing the filter replace it with a new one, available here.
