—SHIFT SOLENOID B (SHIFT SOLENOID 2)
ELECTRICAL (SFT2)—
OBD0048D
DESCRIPTION:
These solenoids are mounted to the control valve. They
are turned ON or OFF according to signals sent from the
TCM. The gear positions are changed according to the ON
and OFF condition of these solenoids.
Controls shift stage by turning solenoid ON/OFF. Rela-
tionship between solenoid operation and shifting stage is
shown in table below. When shifting, timing is controlled for
each solenoid to reduce shock.
DTC DETECTING CONDITION:
Two consecutive trips with fault
TROUBLE SYMPTOM:
No shift

MALFUNCTION (OVR
—F)—
OBD0048E
DESCRIPTION:
This solenoid is also mounted to the control valve. It is
turned ON or OFF according to the signal sent from the
TCM. This operation controls the engagement and disen-
gagement of the overrunning clutch.
Controls 3-2 shift timing and overrunning clutch opera-
tion. Shift timing is controlled by controlling release speed
of oil pressure to reduce shock while down shifting. The
overrunning clutch is controlled so that it will operate dur-
ing coasting to apply engine brake.
DTC DETECTING CONDITION:
Two consecutive trips with fault
TROUBLE SYMPTOM:
Ineffective engine brake with selector lever in“3”
