4R75E TransmissionAlthough similar in design, the Ford 4R70W/E and 4R75W/E transmissions differ in that the 4R75 offers significant improvements and revisions that include a revised fluid pump, a ring gear that has been strengthened, and a torque converter that is stronger as well. Introduced for the 2003 model year to be a more durable alternative to the 4R70, the 4R75 is a lighter duty transmission that is commonly found in 4.6L V8 engines, and the larger V-8 with a 5.4L beginning in 2004 used the 4R75 transmission exclusively. With the exception of the electronic speed sensor that is found on the latter of the two units, the 4R75W and the 4R75E transmissions are identical in design. Both units are considered maintenance-free "filled for life" systems as they feature a case that is sealed.

Like many considerations of the 4R75W/E and 4R70W/E transmissions, the ratios are identical to one another's. Both the 4R75W/E and the 4R75W/E were offered at the same time throughout the time period of 2003 to 2005, the 4R70E ceased being offered in U.S. applications at the completion of the 2005 model year. The 4R75E was offered through the 2008 model year but did not make a return in 2009 with the 6R80 taking its place in Ford's F-150 lineup. The "E" models of the transmission utilize a smarter shift schedule that resulted from greater integration between the engine's PCM and its transmission sensors.
