We wish to thank Ford Motor Company
for the information and illustrations
that have made this booklet possible.
The Ford 5R55S and 5R55W transmissions are both very similar in design to the Ford 5R55N transmission and
use electronic shift controls. The 5R55S/W are both "Syncrounous" units, as they do not use the intermediate
clutch and intermediate sprag that the 5R55N incorporates. The Ford 5R55S and 5R55W transmissions were
introduced in 2002, found in the Ford Explorer and Mercury Mountaineer vehicles, and are available in both
2WD and 4WD configurations. For model year 2003 they are also in the Lincoln LS, Lincoln Aviator and Ford
Thunderbird. They are designed for operation in longitudinal powertrains for rear wheel drive vehicles.
