This is the DOWNLOAD link for the 4R100 TechTran covering the 4R100 Ford transmission found in 1999 and up trucks.
The Ford 4R100 transmission is an updated version of the E4OD and was first introduced in the 1999 model year, and is currently found in the F250, F350, F450 and F550 Super Duty trucks, E150, E250, E350, E450 vans and the Expedition/Navigator/Excursion vehicles equipped with the 5.4L, 6.8L, and 7.3L engines. Some of the 4R100 units are equipped with a Power-Take-Off (PTO) window on the left hand side of the transmission case. The revisions in the 4R100 have created many new engineering changes that have affected many of the internal and external parts that will affect the servicing, repairing and overhaul of these units.
Note: ATSG also has available an "Update Handbook Download" which includes the many changes and is required along with this manual for a proper overhaul or repair.
