Doc's Diesel Transmission Filter Kit for Ford 6.7L Powerstroke 2011–2019 — 6R140 Fit, OEM Interchange

Doc's Diesel Transmission Filter Kit replaces the original filter in Ford 6.7L Powerstroke trucks (2011–2019) to protect transmission components and maintain smooth shifts.

Keeping the transmission filter in good condition is vital for towing-capable diesel trucks. This Doc's Diesel kit is engineered to trap contaminants that can damage the torque converter, pump, and valve body in Ford F-250, F-350, F-450 and F-550 trucks with the 6R140 transmission. The kit matches common OEM and premium aftermarket references so you can install with confidence.

How does this filter kit protect my transmission under heavy loads?

The filter captures metal shavings, clutch material, and grit before they circulate, reducing wear on the torque converter and hydraulic pump. Cleaner fluid runs cooler and keeps shift timing more consistent when towing or hauling.

• Traps debris that causes abrasive wear and clogging.
• Reduces heat build-up by improving fluid flow.
• Helps maintain hydraulic pressure for precise shifting.
• Compatible with 6R140 transmissions for correct fitment.

Will this fit my Ford F-250/F-350/F-450 from 2011–2019?

The kit is made specifically for Ford trucks equipped with the 6.7L Powerstroke and 6R140 transmission across 2011–2019 model years. Always confirm fitment against your vehicle’s options and the fitment card before purchasing to avoid returns.

How often should I replace the transmission filter and why?

Service intervals vary by use and manufacturer recommendations; typical replacement falls between 25,000 and 50,000 miles, with 60,000 miles as an outer limit. Frequent towing, dusty conditions, or hard use justify earlier changes to protect internal components and avoid costly repairs.

• Up to 60,000 miles maximum—shorten interval under heavy duty use.
• Replace earlier if diagnostics show contamination or pressure loss.

What comes with the kit and is installation straightforward?
