Filter and pan gasket to service a Ford 6R80 6-speed in the F-150, Expedition, Mustang and Lincoln Navigator. Replaces FT-188 / BL3Z-7A098-A.
This is the filter and pan gasket you need to service a Ford 6R80 six-speed in an F-150, Expedition, Mustang or Lincoln Navigator. It replaces Ford BL3Z-7A098-A and the FT-188 aftermarket number. Owners usually land here for one of three reasons: the truck is past 100,000 miles and has never had the pan down, the pan rail is weeping fluid, or a shop found debris and the shifts have started to feel soft or late.
The 6R80 pump draws all of its fluid through this filter before sending it to the valve body, the five clutch packs and the converter. Clutch dust, steel fines and varnish collect in the media over time, and as it loads up the pump has to pull harder. A restricted filter lets the pump cavitate, which drops line pressure and heats the fluid. The filter is not bolted in. Its neck pushes into a seal in the valve body and the pan holds it in place, so the pan gasket and the filter seal together decide whether the pump pulls clean oil or air.
A filter will not cure a burned clutch, a failed lead frame or a worn valve body. If the truck sets speed sensor codes or starts in a high gear, read our 6R80 common problems guide before treating it as a service issue.
Look at the fluid first. Pull the fill plug and compare the color and smell with fresh MERCON LV. Once the pan is off, look at the magnet and the bottom of the pan: a light gray paste is normal wear, while flakes of friction lining or chunks of metal mean the transmission needs more than a filter. GEARS Magazine makes the same point about using a clean pan to rule out burnt clutches before chasing solenoid or valve body faults. Our 6R80 filter and pan service guide walks the whole job with photos.
Listed for the 6R80 in 2009-2017 Ford Expedition, 2011-2017 F-150, 2011-2017 Mustang and 2011-2017 Lincoln Navigator. Ford used more than one filter across the 6R family, and the earlier 6R60 and 6R75 style takes a different part, the 7L1Z-7A098-A filter and gasket kit.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
BL3Z-7A098-A, also sold as FT-188. If your old filter carries 7L1Z-7A098-A, use the FT-171 style kit instead.
About 5 to 6 quarts on a pan drop, out of roughly 13 quarts dry. Use MERCON LV and check the level hot with the engine running.
Ford's schedule lists a fluid and filter change at 150,000 miles under normal use. Trucks that tow, idle a lot or run hot benefit from servicing it much sooner.
It is not worth the risk. A hardened gasket is the usual cause of a slow pan weep, and this kit includes a new one.
Only if the cause was low pressure from a restricted filter or old fluid. Lead frame, solenoid and valve body faults need their own repair.
