Sportage 4WD 2Dr L4-2.0L (2002)
When the transmission is in 2nd, 3rd or 4th (O/D) gear, a signal from the TCM turns the torque converter clutch solenoid OFF, and spring tension
forces the solenoid to seat. This seals off the line pressure drain path. With line pressure applied to both ends of the torque converter control valve, the
valve is forced to seat by spring tension. This allows converter pressure (regulated lower than line pressure by the secondary regulator) to be routed
through the torque converter control valve to the converter. In the torque converter, converter pressure acts against the front of the clutch to force it
away from the front cover. The torque converter clutch is now disengaged. Converter pressure is exhausted through the torque converter control valve
to the oil cooler, then back to the oil pan.
Mechanical Operation - Torque converter clutch OFF (Disengaged)
Since the torque converter clutch is physically splined to the turbine, the turbine and clutch always rotate as a unit. The application of fluid pressure
between the front cover and the clutch forces the clutch away from the front cover. This action mechanically breaks the connection and releases the
clutch.
