Service Your Transmission Right The First Time

If you're going to take the time to service your transmission, you might as well do it right, and the Merchant 10715 Internal Filter & Spin-On Combo makes that easier than ever. Designed for 2006–2018 Silverado and Sierra 2500HD and 3500HD trucks with the 6.6L Duramax, this combo kit gives you everything you need for a proper transmission service. It includes both the internal filter and the genuine Allison external spin-on filter, so you're not cutting corners or risking premature wear. This kit is specifically made for trucks equipped with shallow pans, which makes it perfect for most stock applications. Whether you’re trying to stay ahead on maintenance or freshening up a newly acquired truck, replacing both filters at once is a smart move. Clean fluid flow and proper filtration mean smoother shifts, better cooling, and long-term reliability. If you want your truck to last, this is one of the simplest and most effective ways to keep it running strong.

Designed For Complete Filtration And Fluid Protection

The Merchant 10715 Internal Filter & Spin-On Combo is engineered to meet the service needs of 2006–2018 GM 6.6L Duramax trucks using shallow transmission pans. The kit includes two essential components: a high-quality internal transmission filter and a genuine Allison-branded external spin-on filter. This dual-filter approach ensures that both primary and return line fluid paths are properly protected, helping to prevent debris from circulating through your transmission. Proper filtration plays a critical role in maintaining pressure regulation, fluid clarity, and consistent hydraulic performance. The internal filter installs inside the transmission case to capture larger particles, while the spin-on filter provides additional protection for the fluid return path. This kit is highly recommended when performing a complete transmission fluid replacement or scheduled maintenance. All components are designed to meet OEM standards for fit and function, ensuring a hassle-free installation with confidence. For trucks that work hard or are driven in demanding conditions, this filter combo helps extend service life and maintain optimal shift quality.
