Merchant Automotive 29539579 Allison 1000/2000 External Spin-On Transmission Filter

The Merchant Automotive 29539579 is an OEM replacement external spin-on filter designed for Allison 1000, 2000, and 2400 series transmissions found in 2001-2019 GM trucks equipped with the Duramax diesel engine. This genuine Allison transmission filter plays a critical role in protecting your transmission by trapping dirt, debris, and metal particles before they can cause internal damage.

Key Features:

• Genuine OEM replacement for Allison 1000 and 2000 transmissions
• Compatible with Allison 1000, 2000, and 2400 series transmissions
• Easy spin-on installation and replacement design
• Located on the driver side of the transmission for accessible maintenance
• Recommended replacement interval of 12,000 miles for optimal transmission health

Important Installation Note:

When changing this filter, ensure that you clean and reuse the filter magnet that is sandwiched between the filter and the transmission, as this magnet often sticks to the old filter and can be discarded by mistake. If your magnet is missing, replacement magnets are available separately (Allison part number 29535617).

This external spin-on filter works in conjunction with your transmission's internal filter to provide comprehensive filtration protection. Regular maintenance of both filters ensures smooth shifting, prevents premature wear, and extends the life of your Allison transmission.
