Automatic Transmission - Ford 1997 Aerostar Manual

Steering Your Vehicle
Your vehicle comes with power steering. Power
steering uses energy from the engine to help
steer your vehicle.
If the amount of effort needed to steer your
vehicle changes at a constant vehicle speed, have
the power steering system checked. If the power
steering system breaks down (or if the engine is
turned off), you can steer the vehicle manually
but it takes more effort.
Never hold the steering wheel to the extreme
right or left for more than five seconds if the
engine is running. This can damage the power
steering pump.
NOTE: After any severe impact such as
striking large potholes, sliding into
curbs on icy roads, or a collision
involving the front end, observe the
steering wheel alignment. If the spokes
of the steering wheel seem to be in a
different position while going straight
down the road, have the front
suspension and steering checked for
possible damage.

Automatic Transmission

Operation (4R44E/5R55E)
If your vehicle is equipped with an automatic
transmission, it will be either a four speed
overdrive transmission (4R44E) or a five speed
overdrive transmission (5R55E). All 3.0L engines
use the 4R44E transmission, while all 4.0L
engines use the 5R55E transmission. Both
transmission types have a lockup torque
converter. Transmission operation is controlled
by the Powertrain Control Module (PCM).
