FORD 5R55N VERSUS 5R55W
TRANSMISSION DIFFERENCES
The Ford Motor Companys 5R55N (Non Sync.) transmission first appeared in the 2000 Lincoln "LS" and some
of the Jaguar Models, which we are already somewhat familiar with. Beginning at the start of production for
model year 2002, Ford has introduced the 5R55W (Wide Ratio) transmission into the some 4WD models of the
Ranger and Explorer, and the 5R55S (Sync) transmission into some of the 2WD Ranger/Explorer and the 2004
Thunderbird. The internal parts look almost identical, but will not interchange with their look alikes in the
5R55N transmission. The information in this bulletin will help you in getting the proper replacement parts back
into the proper unit. Externally these transmissions are easy to identify and we have provided illustrations of
both transmissions in Figure 191.
Figure 192 is an illustration of the two different turbine shafts. They are identical in every respect except for
the overall length.
Figures 193 and 194 show you the differences in the overdrive sun gear and drive plate. Notice the
differences in the tooth count on the sun gear.
Figures 195 and 196 are illustrations of the two different coast clutch housings. Notice that the slots to
accept the tabs on the adapter plate are narrower and angled to the left at a very slight angle. This means that
it will engage into the coast clutch housing in only one direction.
