FORD 5R55S/5R55W

When in the Park position, there is no power flow
through the transmission and the parking pawl locks
the output shaft to the case. The engine may be started
and the key may be removed.
When in the Neutral position, there is no power flow
through the transmission, the output shaft is not held
and is free to turn. The engine may be started and the
key can not be removed.
When in the D position, with the TCS switch "OFF",
there will be automatic upshifts 1st through 5th gear,
automatic downshifts 5th through 1st gear, and apply
and release of the TCC depending on vehicle speed,
throttle position and engine coolant temperature.
This is the normal position for most forward driving
and provides the maximum fuel economy during
normal operation. This unit also has engine braking
in 5th gear.
When in the D4 position, with the TCS switch "ON",
there will be automatic upshifts 1st through 4th gear,
automatic downshifts 4th through 1st gear, and apply
and release of the TCC depending on vehicle speed,
throttle position and engine coolant temperature.
This position may be selected for towing, or driving in
hilly terrain. This unit also has engine braking in 4th
gear.
This position provides a pull-in shift to 2nd gear with
coast braking. After an automatic downshift, a 2nd
gear hold occurs with coast braking. In this position
2nd gear starts occur.
This position provides a pull-in shift to 3rd gear with
coast braking. After an automatic downshift, a 3rd
gear hold occurs with coast braking. In this position
3rd gear starts occur.
This position provides 1st gear operation only, and
used for descending steep grades. If this position is
selected at normal road speeds, the transmission will
downshift to the next lower gear, and continue
downshifting at safe pre-calibrated road speeds until
it reaches 1st gear.
When in the Reverse position, the vehicle may be
operated in a rearward direction at a reduced gear
ratio, and the back-up lamps are illuminated.
