TROUBLE DIAGNOSIS FOR SHIFT SOLENOID/V A
AT-64
Shift Solenoid Valve A
DESCRIPTION
Shift solenoid valves A and B are turned “ON” or “OFF” by the TCM
in response to signals sent from the park/neutral position switch,
vehicle speed and throttle position sensors. Gears will then be
shifted to the optimum position.

DIAGNOSTIC PROCEDURE
CHECK GROUND CIRCUIT.
1. Turn ignition switch to “OFF” position.
2. Disconnect terminal cord assembly con-
nector in engine compartment.
3. Check resistance between terminal

1. Remove control valve
assembly. Refer to
AT-118.
2. Check the following
items:

Harness of terminal cord
assembly for short or
open
CHECK POWER SOURCE CIRCUIT.
1. Turn ignition switch to “OFF” position.
2. Disconnect TCM harness connector.
3. Check resistance between terminal
