Reset Memory
e Engine Control Module (ECM) in these transmis-
sions adapts to the conditions of the engine and trans-
mission assemblies. When replacing the engine, trans-
mission, valve body or the ECM you must reset the
memory so that the ECM can adapt to new conditions.
Follow OE procedures to reset the memory. Afterwards,
follow the OE road test procedures.
Flex Lockup Clutch Control
e ECM regulates the SLU solenoid to provide an
intermediate mode between the On/O operation of
the converter clutch in the low-to-mid-speed range.
is is for improved fuel economy. Lockup control is
prohibited if the brake is depressed, the accelerator pedal
is released or engine coolant temperature is below 140°F.
