4R70W / 4R75E
4-speed RWD. Mercon V. Forward drum / reverse clutch are the high-failure items. Classic rebuild, well-stocked aftermarket.
Shop 4R70W / 4R75E PartsMost F-150 rebuilds we ship parts for are 6R80s (2009-2014 F-150 fleet trucks). Mercon LV fluid is mandatory - wrong fluid voids the rebuild within 5K miles.
