4R70W 4R75W 4R75E Transmission Filter & Gasket Kit Ford FT105

This is the service filter and pan gasket for the Ford 4R70W, 4R75W and 4R75E automatic, the overdrive box that sits behind the 4.6L and 5.4L V8 in a huge run of Ford, Lincoln and Mercury rear-drive vehicles. It replaces OE part numbers FT105, F6AZ-7A098-A and 58955. Before you order, match your old filter against those numbers — this is the shallow valve-body filter, not a deep-pan unit.

Fitment covers F-150 1996-2010, Mustang 1996-2004, Expedition 1997-2006, E-150/E-250/E-350 vans, Crown Victoria 1996-2011, Lincoln Town Car, Mercury Grand Marquis and Mountaineer. On the bench the job is straightforward: drop the pan, pull the old filter straight down off the pump pickup, seat the new filter until the neck seal is fully home in the case, then lay the fresh gasket and torque the pan bolts evenly. A filter that is not fully seated is the usual cause of low-pressure and slipping complaints after a service, so make sure the neck seats before the pan goes up.

Changing the filter and fluid on schedule keeps metal and clutch debris out of the pump and valve body, which is the cheapest insurance there is against a slipping 4R70W. Reviewers note the filter itself fits and flows well; if you want extra peace of mind against a weeping pan, a reusable rubber-and-steel gasket from the parts store pairs fine with this filter.
