Doc's Diesel Transmission Filter Kit DF-211 - Smooth Shifts for RAM

In this review of the Doc's Diesel Transmission Filter Kit DF-211 the bottom line is simple: it is for owners of Ram 6.7L Cummins 2500 and 3500 trucks with the 68RFE transmission who want a reliable, affordable replacement filter that helps keep shifts smooth and reduces risk of costly transmission wear. The reviewer found the kit does exactly what it promises - traps debris that can damage the torque converter and fluid pump - and delivers noticeable benefits to drivability and long-term maintenance when changed on a regular schedule.

Key Features

• Filtration performance: The filter traps dirt and debris that can damage the torque converter and fluid pump, helping preserve transmission components and reduce repair risk.
• Fitment compatibility: Designed to fit Ram 6.7L Cummins 2500 and 3500 models with the 68RFE transmission 4WD from 2007.5 through 2024, simplifying parts selection for these trucks.
• OEM interchange: Replaces Mopar 5013470AC and equivalents from other makers, so it can be used as a direct aftermarket replacement during service.
• Maintenance guidance: Recommended change interval of 25,000-50,000 miles (up to 60,000 max) gives a clear schedule to help protect the transmission and maintain fuel efficiency.
• Value proposition: Built as an aftermarket alternative that aims to match OEM standards, offering a budget-friendly option without sacrificing basic performance.

Who It's For

This kit is best for Ram owners who perform regular maintenance themselves or work with a trusted shop and need a transmission filter that fits 68RFE-equipped 6.7L Cummins trucks from 2007.5 to 2024.
