Master overhaul kit for the 4F27E and Mazda FN4A-EL four-speed with frictions, pistons, separator plates, gaskets and the complete seal set.
A worn 4F27E usually shows up as a slow engagement into Drive, a missing or skipped second gear, or a 2-3 shift that flares after the clutches wear. This master overhaul kit covers the Ford 4F27E and the matching Mazda FN4A-EL used in the Focus, Fiesta, Mazda3 and others. Unlike most soft-parts kits, it includes new bonded pistons along with the friction plates, separator plates, gaskets and complete rubber and lip seal set.
The 4F27E is a four-speed front-wheel-drive transaxle shared by Ford and Mazda. Mazda sells it as the FN4A-EL, and Ford and Mazda name the shift solenoids differently. It uses a forward clutch, a direct (third) clutch, a reverse clutch, a low/reverse brake and a 2-4 band. On a high-mileage unit, the forward clutch drum turns on the turbine shaft and is held in line by the pump-stator bushings, so wear in one area quickly spreads to the others. This kit replaces the clutch plates, the bonded piston seals and the case and valve body gaskets, so every circuit can hold pressure again after the teardown.
Several 4F27E complaints come from the valve body, not the clutches. TransGo lists wrong-gear starts, no second, skipped second and TCC slip codes as faults its valve body repair kit fixes. Transmission Digest notes that a P0741 usually means the converter clutch is slipping, not that a solenoid is bad, and the most common cause is leakage past the rear pump-stator bushings. That leak gets worse when the fluid is hot and thin. If the fluid is clean and the complaint is shift quality, start with our slipping diagnosis guide and check the valve body first. If the fluid smells burnt and there is friction material in the pan, plan on a full overhaul.
The listing covers the Ford Fiesta 2008-2017 (1.3L/1.4L/1.5L), Focus 1999-2011 (1.8L/2.0L Zetec and Duratec), Focus C-Max 2000-2011, EcoSport 2007-2012 (2.0L) and Transit Connect 2009-2013 (2.0L). Mazda coverage includes the Mazda2 2005-2014, Mazda3 2004-2008 (2.0L/2.3L), Mazda5 2006-2010, Mazda6 2003-2005 (2.3L), Protege 1999-2003 and CX-7 2006-2010. Listed cross-references include K71900KF, DP2351, XS4Z-7A098-AB and FN01-21-500. Check your transmission ID tag against those numbers. If the tag is gone, send us the year and VIN before you order. Other 4F27E parts are on our 4F27E parts page.
This kit does not include the band or filter. Add a filter and pan gasket kit. If the valve body has worn bores, rebuild it with the TransGo 4F27E valve body repair kit while it is apart.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. It is the same four-speed transaxle under Ford and Mazda names, and this kit covers both. The solenoids are named differently by each maker, so use the right chart when you diagnose a code.
It includes pistons, friction plates, separator plates, gaskets and the full seal set. It does not include the 2-4 band or a filter.
Only if the cause is inside the transmission. P0741 means the converter clutch is slipping too much, and the usual cause is leakage at the rear pump-stator bushings or worn converter clutch valve bores. Check those along with the converter before you blame the solenoid.
A common cause is a cracked 2-4 servo piston or a worn servo pin bore in the case. Check both on every overhaul, and bore and bush the case if the pin is loose.
Use MERCON V on Ford applications. On Mazda-badged units, use the fluid listed in the owner's manual or on the dipstick. Soak the new frictions in that fluid before assembly.
