OVERDRIVE SWITCH (Continued)
OPERATION
At key-on, overdrive operation is allowed. Pressing
the switch once causes the overdrive OFF mode to be
entered and the overdrive OFF switch lamp to be illu-
minated. Pressing the switch a second time causes nor-
mal overdrive operation to be restored and the overdrive
lamp to be turned off. The overdrive OFF mode defaults
to ON after the ignition switch is cycled OFF and ON.
The normal position for the control switch is the ON
position. The switch must be in this position to energize
the solenoid and allow a 3-4 upshift. The control switch
indicator light illuminates only when the overdrive
switch is turned to the OFF position, or when illumi-
nated by the transmission control module.
DIAGNOSIS AND TESTING - OVERDRIVE
ELECTRICAL CONTROLS
The overdrive off switch, valve body solenoid, case
connectors and related wiring can all be tested with
a 12 volt test lamp or a volt/ohmmeter. Check conti-
nuity of each component when diagnosis indicates
this is necessary.
Switch and solenoid continuity should be checked
whenever the transmission fails to shift into fourth
gear range.

INSTALLATION
NOTE: There is enough slack in the wire to pull out
the connector from the lever.

to grasp it.
CAUTION: Be careful not to bend the pins on the
overdrive off switch. Use care when installing the
switch, as it is not indexed, and can be accidentally
installed incorrectly.

tor (Fig. 185)
