Explorer 4WD V6-4.0L (2009)
During TCC apply, transmission fluid flows through the torque converter in the opposite direction to apply the 3-plate clutch.
The TCC operates in 3 stages:
-
Full release
-
Controlled modulation
-
Full apply
The Transmission Control Module (TCM) controls TCC operation using the TCC solenoid. TCC solenoid operation provides the modulation of
hydraulic pressure to change the position of the bypass clutch control regulator valve. The valve changes the pressure and direction of transmission fluid
flow in the torque converter. The TCC may be applied in forward gears, 2 to 6.
