SHIFT INTERLOCK SYSTEM
DESCRIPTION
The Brake Transmission Shifter/Ignition Interlock
(BTSI) is a cable and solenoid operated system that
prevents the transmission gear shifter from being
moved out of PARK without a driver in place.
Refer to the following chart that expected shifter
response, depending on ignition key/switch (Fig. 319)
and brake pedal positions.
DIAGNOSIS AND TESTING - BRAKE/
TRANSMISSION SHIFT INTERLOCK SYSTEM

of the Brake Transmission Shift Interlock (BTSI) sys-
tem. If the “expected response” differs from the vehi-

SOLENOID/PRESSURE
SWITCH ASSY
DESCRIPTION
The Solenoid/Pressure Switch Assembly (Fig. 324)
is external to the transaxle and mounted to the
transaxle case. The assembly consists of four sole-
noids that control hydraulic pressure to the LR/CC,
2/4, OD, and UD friction elements. The reverse
clutch is controlled by line pressure from the manual
valve in the valve body. The solenoids are contained
within the Solenoid/Pressure Switch Assembly, and
can only be serviced by replacing the assembly.
The solenoid assembly also contains pressure
switches that monitor and send hydraulic circuit
information to the PCM/TCM. Likewise, the pressure
switches can only be service by replacing the assem-
bly.
OPERATION
SOLENOIDS
The solenoids receive electrical power from the
Transmission Control Relay through a single wire.
The PCM/TCM energizes or operates the solenoids
individually by grounding the return wire of the sole-
noid needed. When a solenoid is energized, the sole-
noid valve shifts, and a fluid passage is opened or
