Filter and pan gasket for the Ford 6R60/6R75/6R80 (7L1Z7A098A, FT171), fitting 2006-2010 F-150, Expedition, Explorer, Navigator and Mountaineer.
This is the service kit for the first generation of Ford's six-speed rear-drive automatic: the 6R60, 6R75 and 6R80 built before the 2011 redesign. It replaces Ford 7L1Z-7A098-A, the 7L1P-7G186-AB and -AD numbers and B368, cross-referenced as FT171, and covers 2006-2010 Expedition, Navigator, Mark LT, F-150, Explorer, Sport Trac and Mountaineer applications. Owners of these trucks usually start shopping after the fluid has gone dark, the pan rail starts weeping, or the shifts have gone soft and slow when warm and they want to see what is in the pan before spending more.
Ford's 6R family is its version of the ZF 6HP26, first used behind the 5.4L in the 2005 Expedition and Navigator. Everything the pump sends to the valve body, the five clutches (A, B and E driving, C and D braking) and the lockup converter is pulled up through this filter first. On these early units there is no one-way clutch, so the D clutch stays applied through all of first gear and the 1-2 shift is a straight clutch-to-clutch handoff. That makes them sensitive to line pressure. A loaded filter makes the pump work harder, aerates the oil and lets pressure sag, and you feel it as a slow engagement or a flare between gears. The filter is not bolted in: its neck seats in a seal in the valve body and the pan holds it there, so the 21-bolt pan gasket and that seal decide whether the pump draws clean fluid or air.
A new filter cannot fix a burned clutch pack or a sticking valve. Harsh, banging shifts, a start in a high gear or speed sensor codes belong to the controls, which our Expedition 6R80 problems guide walks through.
Check the level and condition first, with the engine running at operating temperature, so you know what you are dealing with. When the pan comes down, read it: fine gray paste on the magnet is normal, while flakes of brown friction lining, brass or chunks of steel tell you the unit needs an overhaul, not a filter. Our 6R80 filter and pan service guide covers the drop step by step and shows what a healthy pan looks like.
Listed for the Expedition 5.4L (6R75/6R80) 2007-2010, Explorer and Explorer Sport Trac 2007-2010, F-150 4.6L, 5.4L and 6.2L (6R80) 2009-2010, Lincoln Mark LT 5.4L 2006-2008, Navigator 5.4L 2008-2010 and Mercury Mountaineer 2007-2010. Two cautions. Not every Explorer or Mountaineer from those years has the six-speed, so check the transmission code on the door-jamb label before ordering. And some early 6R60 applications use a shallow pan with a different filter neck, so compare pan depth and pickup shape with the parts you remove, or send us your year and VIN. If your truck is a 2011 or later build with the one-way clutch case, you need the later FT-188 filter and gasket kit instead. The full lineup is in the 6R80 collection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. 2011 and later 6R80 units got a new case, a one-way clutch and a different filter. They take the FT-188 (BL3Z-7A098-A) kit. This FT171 kit is for the earlier 2006-2010 style units.
One transmission filter with its neck and one 21-bolt pan gasket. Fluid is not included, and the filter seal in the valve body should be checked and replaced if it is hard or torn.
These early six-speeds were filled with MERCON SP. Ford's Motorcraft literature allows MERCON LV for top-off and full-service replacement in 6R60/6R75 and 6HP26 transmissions. Check your owner guide and never mix in a generic universal ATF.
Read the transmission code on the door-jamb certification label or decode the VIN. Not every Explorer, Sport Trac or Mountaineer from 2007-2010 used the six-speed. Send us the VIN if you are unsure.
It is part of the repair, but not the whole repair. Heavy friction or metal debris means worn clutches or bushings, and the unit needs an overhaul or a replacement transmission. A filter alone will not restore slipping clutches.
Not usually for a filter and gasket alone. If shifts feel off afterward, check the fluid level hot first. Adaptive values reset only if the battery or the controller is cleared.
