Transmission Lookup



The 5R55E, though mechanically similar to the 4-speed 4R55E, was a new breed of electronically controlled automatic transmission with an additional forward gear. It was the first 5-speed automatic transmission to be employed by an American automaker. The 5R55E featured more precise computer controls (necessary to accommodate the additional forward gear) and introduced an with a sophisticated friction-to-friction shift ability. Like the 4R44E relative to the 4R55E, a version of the 5R55E was made for lighter duty applications: the 5R44E. An example of these transmissions used in a single vehicle line would be in recent versions of the Ford Ranger pickup where the lighter-duty 5R44E is mated to a 3.0L Vulcan OHV V6 while the heavier duty 5R55E is mated to the more powerful 4.0 L Cologne SOHC V6.
