*: Activate the Solenoid (SLT) in the Active Test is performed to check the line pressure changes by
connecting SST to the automatic transmission, which is used in the Hydraulic Test
as well. Note that
the pressure values in the Active Test and Hydraulic Test are different.

Pressure Control Solenoid "D" Performance (Shift Solenoid Valve SLT)
DESCRIPTION
Shift solenoid valve SLT controls the transmission line pressure for smooth transmission operation based on
signals from the throttle position sensor and vehicle speed sensor. The ECM adjusts the current to shift solenoid
valve SLT to control the hydraulic line pressure coming from the primary regulator valve. Appropriate line
pressure assures smooth shifting with varying engine outputs.

MONITOR DESCRIPTION
When the shift solenoid valve SLT remains ON, oil pressure decreases, which causes the clutch
engagement force to decrease.
When the shift solenoid valve remains ON or OFF, the gear position commanded by the ECM and the
actual gear position are not the same.
NOTICE:
If you continue driving under these conditions, the clutch will burn out and the vehicle will no longer be
drivable.
