Torque converter clutch solenoid performance (shift solenoid valve dsl)
Description
The ecm uses the signals from the throttle position sensor, air-flow meter,
turbine (input) speed sensor,
intermediate (counter) shaft speed sensor and crankshaft position sensor to
monitor the engagement
condition of the lock-up clutch.
Then the ecm compares the engagement ...
Shift solenoid "d" performance (shift solenoid valve s4)
System description
The ecm uses signals from the output shaft speed sensor and input speed
sensor to detect the actual
gear position (1st, 2nd, 3rd or o/d gear).
Then the ecm compares the actual gear with the shift schedule in the ecm memory
to detect mechanical
problems of the shift s ...
