Doc’s Diesel Transmission Filters + Replacement Kits
Keep Your Transmission Running Strong
Whether you’re running a RAM Cummins, Duramax, Powerstroke, or EcoDiesel, Doc’s transmission filters are engineered to handle your workload. Keep your torque converter and pump protected, your fluid clean, and your truck shifting just like it should. Your transmission filter is the first line of defense against debris and contaminants. A clean filter keeps fluid flowing freely, prevents overheating, and ensures smooth gear shifts, protecting critical components like the torque converter and fluid pump from costly damage.
Built to Meet or Exceed OEM Standards
Every Doc’s Diesel transmission filter is engineered to perform as good, or better, than factory parts. Doc’s Diesel Transmission Filters work hard to trap dirt, metal shavings, and gunk that otherwise clog your fluid, overheat the system, and destroy your torque converter or fluid pump. A clean filter means cooler operation, less wear, and smarter fuel economy, so you stay on the road, not in the shop. You can trust our filters to handle the demands of your truck, whether you’re hauling, towing, or driving daily.
Doc’s Diesel Fitment Guarantee
Our transmission service kits include everything you need: filter, gaskets, and more, so you’re ready for a full service without hunting for parts. Shop by engine type and get exactly what fits. No guesswork. No hassle. Every filter comes backed with Doc’s fitment guarantee so you know you’re getting the right part for your truck. That means they flow better, last longer, and keep contaminants out where they belong.
