Automatic Transmission
Operation (E4OD)
[DR08712( M)03/94]
The E4OD transmission is an electronically
controlled four speed automatic transmission
with overdrive. Transmission operation is
controlled by the Powertrain Control Module
(PCM).
*
[DR08720( ALL)08/94]
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 is first driven and has
not reached normal operating temperature.
*
[DR08730( ALL)07/94]
The PCM also controls the transmission's Torque
Converter Clutch to further raise vehicle
performance and fuel economy. The Torque
Converter Clutch 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 after an upshift has
completed or when the driver has depressed the
throttle while driving at a steady road speed.
