2002 NISSAN TERRANO Service Repair Manual

Shift Solenoid Valve A
DESCRIPTION
Shift solenoid valves A and B are turned ªONº or ªOFFº 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.
