The Ford 4R44E / 4R55E is a fully electronic controlled, four speed, rear wheel drive transmission. At first glance it resembles the familiar A4LD transmission. The shift timing, shift feel, line pressure and TCC are all computer controlled in the 4R44E/4R55E transmissions. There are three compound planetary gearsets, three bands, three multi-disc clutch packs and two one-way freewheel assemblies.
