The PCM will automatically adjust transmission
operation to make up for varying conditions.
Several sensors located on the engine and
transmission such as throttle position, engine
speed, vehicle speed and transmission
temperature are used by the PCM to shift the
transmission into a higher or lower gear when
required for the best performance and fuel
economy. For example, you may notice that the
transmission will upshift to a higher gear more
quickly when the vehicle has not reached normal
operating temperature.

The PCM also controls the transmission's Torque
Converter Clutch (TCC) to further raise vehicle
performance and fuel economy. The TCC will
engage when the transmission operating
temperature and other conditions determined by
the PCM have been met. Engagement of the
clutch may be noted as a decrease in engine
speed.

To help in troubleshooting, the PCM continually
performs self-tests on the electronic control
system and, if any faults are detected, stores
them in memory. The Transmission Control
Indicator Light (TCIL) (O/D OFF), which is
located on the gearshift lever, may flash steadily
if a malfunction has been detected. If the TCIL is
flashing, contact your Ford dealer as soon as
possible. If this condition persists, damage to the
transmission could occur.

All models are equipped with a Powertrain
Control Module (PCM) which limits the
maximum engine speed and thus road speed in
top gear. Vehicle operation is normal since the
controlled maximum speed is above posted
highway speeds in North America.
