Which vehicles and transmissions is this filter kit compatible with?

The Fitede kit is built specifically for the 4F27E (FN4A-EL) automatic transmission. It fits a range of Ford and Mazda models across model years where that gearbox was installed.

• Ford: 2010–2013 Transit Connect, 2000–2016 Focus
• Mazda: 1999–2009 model coverage includes Protege, Protege5, Tribute, 3 (2004–2009 and 2009 3 Sport), 5, and 6
• Confirm compatibility by matching your vehicle’s OEM part number to the replacements listed

How does this filter kit help maintain transmission performance?

The filter captures metal shavings, clutch material and other debris that accumulate in automatic transmissions, reducing the chance of valve body blockages and wear. A clean fluid circuit helps maintain shift quality and extends component life without altering factory hydraulics.

• Precision media traps contaminants before they circulate through the valve body
• New gasket ensures a secure pan seal to prevent leaks
• Manufactured to meet or exceed OEM tolerances for fit and flow

What’s included in the kit and what quality assurances come with it?

The package contains one automatic transmission filter and one pan gasket for a complete lower-end service. Fitede tests every product before shipment and provides a 12-month warranty plus a straightforward return policy for buyer confidence.

• 1 x transmission filter and 1 x pan gasket included
• 100% factory-tested to verify fit and function
• 12-month warranty and hassle-free returns

How should I install this kit and what should I watch for during service?

Installation follows standard transmission service procedures: drain fluid, remove pan, replace filter and gasket, then refill with correct fluid type and volume. Inspect the pan for metal debris and the magnet for excessive particles to gauge internal wear.

• Use proper torque on pan bolts to avoid gasket distortion
• Replace transmission fluid with manufacturer-specified type and amount
• Check for leaks after a short drive and re-torque if necessary

Who is this for: This filter kit is intended for DIY mechanics and professional technicians servicing Ford or Mazda vehicles equipped with the 4F27E / FN4A-EL transmission who need a reliable, tested replacement filter and pan gasket. It suits owners performing routine transmission maintenance, shops restoring shift quality, and anyone replacing a worn or clogged filter with a part that matches OEM numbers for fit.
