The transmission ratios of the 4R75W/E, like many aspects, are identical to that of the 4R70W/E. While the two transmission were offered simultaneously from 2003 to 2005, the 4R70E was retired in all U.S. applications following the 2005 model year. Usage of the 4R75E continued through the 2008 model year, but the transmission did not return for 2009 and the six speed 6R80 took its place in the F-150's lineup. The "E" models of the transmission employ a more sophisticated, "smarter" shift schedule as a result of greater integration between the transmission's sensors and the engine's vehicle's PCM.
