YzusGomumu E40D/4R100 4WD Transmission Filter Kit — Direct-Fit, High-Temp Gasket

The YzusGomumu E40D/4R100 4WD automatic transmission filter kit is a direct-fit replacement that screens and seals transmission fluid to help protect valve bodies and internal parts.

This complete kit includes a high-temperature resistant filter element and a matching gasket designed to fit a range of Ford models using the E40D/4R100 4WD transmission family. It’s built to resist heat and maintain a tight seal so fluid stays where it should, and contaminants are captured before they circulate through clutches and valves. Before ordering, verify the OE number and vehicle application for compatibility.

Which Ford models is this filter kit compatible with?

The kit is engineered for many Ford trucks, SUVs and motorhome chassis that use E40D or 4R100 four-wheel-drive transmissions. It covers multiple model years across F-Series, Bronco, Expedition, Excursion and Lincoln Navigator lines.

• Applications include F-150 through F-550 variants, F-250/F-350 (including Super Duty), Bronco, Expedition, Excursion, Lincoln Navigator and F-53 chassis.
• Model years span roughly late 1980s through mid-2000s depending on the vehicle and transmission option.
• Check OE references (F3TP-7G186-BB, F6TZ-7A098-BB, YC3Z-7A098-BA, TF-172) for exact fitment.

How does replacing this filter help my transmission?

A fresh filter keeps abrasive particles and debris out of the hydraulic circuits, reducing the chance of clogged valve bodies and worn clutch packs. Cleaner fluid helps the transmission shift more smoothly and can reduce premature wear.

• Removes metal shavings and sludge before they circulate.
• Helps maintain correct hydraulic pressure and shift feel.
• Gasket ensures a secure seal to prevent leaks and fluid loss.

What’s included and what materials are used?

The package contains one transmission filter and one gasket sized for the E40D/4R100 4WD assembly. Components are produced from heat-tolerant materials and designed for long-term sealing performance under transmission operating temperatures.

• One automatic transmission filter element engineered for durability.
• One gasket matched to the filter flange for leak prevention.
• High-temperature resistant construction suitable for transmission environments.

When should I replace this filter and what signs indicate a problem?

Routine replacement is recommended according to your vehicle’s maintenance schedule or when symptoms appear. If you notice rough shifts, slipping, unusual noise, visible leaks, or dark, contaminated transmission fluid, the filter may be clogged or the gasket may be failing.

• Replace during transmission service, fluid flush, or if troubleshooting shift problems.
• Look for gear-change difficulty, rattling, leaks, or dark burnt-smelling fluid.
• Using the correct OE reference ensures correct fit and sealing.

Who is this for: This YzusGomumu kit is aimed at owners, mechanics and fleet managers of Ford trucks, SUVs and motorhome chassis equipped with E40D or 4R100 4WD transmissions who need a reliable, cost-effective replacement filter and gasket. It suits anyone doing routine transmission service, pre-purchase maintenance, or preventive upkeep to extend transmission life and avoid more expensive repairs.
