Fitede 4F27E Automatic Transmission Filter Kit — replaces 58617 | Filter + Pan Gasket, OEM-quality fit

Fitede’s 4F27E Automatic Transmission Filter Kit is a complete replacement filter and pan gasket set designed to fit 4F27E / FN4A-EL gearboxes, restoring cleaner transmission fluid flow and protecting valve bodies from debris.

This kit includes a precision-molded transmission filter and a matching pan gasket engineered to meet or exceed OEM quality. Each unit is 100% tested before leaving the factory and manufactured from high-quality materials to trap contaminants, keep fluid flowing freely, and reduce the risk of internal blockage. It replaces common OE numbers including 58617, FT131, B189, and several Ford/Mazda OEM references.

How will this filter kit affect shifting and fluid cleanliness?

Installing a fresh filter and gasket removes accumulated metal shavings and sludge that restrict fluid passages. Cleaner fluid reduces strain on the valve body and clutch packs so shifting stays consistent and smoother under normal driving conditions.

• New media captures particulates that clog channels.
• Improved flow reduces heat buildup in the transmission.
• Pan gasket replacement prevents leaks that contaminate fluids.

Which vehicles and part numbers is this kit compatible with?

This kit is specified for transmissions labeled 4F27E or FN4A-EL and replaces several OEM part numbers, so verify your vehicle’s part number before ordering. It fits many Ford and Mazda models produced across the late 1990s to mid-2010s.

How do I install the kit and what should I inspect during service?

Installation is a routine service for someone comfortable with draining transmission fluid and removing the transmission pan. While the pan is off, inspect the magnet for heavy metal deposits and check the fluid color and smell—dark, burnt fluid indicates further service may be needed.

• Drain fluid, remove pan, replace filter and gasket, then refill to spec.
• Inspect magnet for metal flakes; large amounts may need professional diagnosis.
• Always use the manufacturer-recommended transmission fluid and check level after warm-up.
