Lock-up Control Solenoid Valve A/B Assembly
NOTE: Lock-up control solenoid valves A and B must be
removed/replaced as an assembly.
L Disconnect 2P connector from the lock-up control
solenoid valve Ay'B assembly.
2. Measure the resistance between the No. 2 terminal
{solenoid valve A) of the lock-up control solenoid
valve connector and body ground, and between the
No. 1 terminal {solenoid valve B) and body ground.
STANDARD: 12 - 25 O
LOCK.UP CONTROLSOLENOID VALVE A/BASSEMBLY
Replace the lock-uo control solenoid valve assem-
bly if the resistance is out of specification.
lf the resistance is within the standard, connect the
No. 1 terminal of the lock-uD control solenoid valve
connector to the battery positive terminal. A clicking
sound should be hea.d. Connect the No. 2 terminal to
the battery positive terminal. A clicking sound should
be heard. Replace the lock-up control solenoid valve
assembly if no clicking sound is heard.
1.Remove the mounting bolts and lock-up control
solenoid valve A/B assemblv.
Check the lock-up control solenoid valve fluid pas-
sages for dust or dirt. and replace as an assembly, if
necessary.

Clean the mounting surface and fluid passages of
the lock-up control solenoid valve assembly, and
install a new lock-up control solenoid valve Ay'B with
a new filter/gasket.
