TORQUE CONVERTER CLUTCH OPERATION REFERENCE

General Description 

The power transfer capacity of the torque converter clutch is controlled by the balance of automatic 
transmission fluid (ATF) supplied to and discharged from the torque converter. When hydraulic pressure is 
applied internally, the torque converter clutch turns ON, and when hydraulic pressure is applied from the back 
pressure side, the lock-up clutch turns OFF. As the hydraulic pressure from the internal pressure side increases, 
the power transfer capacity of the torque converter clutch increases. The direction of hydraulic pressure supply 
is switched by shift solenoid valve E and the lock-up shift valve. ATF is supplied from the internal pressure side 
to shift solenoid valve E when the signal from the powertrain control module (PCM) is ON (12 V), and ATF is 
supplied from the back pressure side when it is OFF (0 V). The balance of internal pressure and back pressure is 
controlled by A/T clutch pressure control solenoid valve A and the lock-up control valve. A/T clutch pressure 
control solenoid valve A maximizes the power transfer capacity of the torque converter clutch when the signal 
from the PCM is ON (1 A), and it minimizes the power transfer capacity of the torque converter clutch when 
the signal from the PCM is OFF (0 A). If the ratio of engine speed and mainshaft speed is not about 1:1 while 
the PCM is issuing the command to turn shift solenoid valve E and A/T clutch pressure control solenoid valve 
A ON, the PCM detects a faulty lock-up control system and stores a DTC.

Malfunction Threshold 

The ratio of the engine revolution to the transmission input pulse does not reach about 100% for at least 20 
seconds. 

Driving Pattern 

1. Start the engine. Hold the engine at 3,000 rpm with no load (in park or neutral) until the radiator fan 

comes on.  

2. Drive the vehicle at a constant speed of 60 mph (96 km/h) for at least 20 seconds. 



Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.
