DIRECT CLUTCH - APPLIED

BASIC CONTROL
When car speed in Drive Range 3rd Gear, reaches converter clutch engagement speed, the C3 or governor pressure switch (depending on system) will activate the solenoid, closing the exhaust valve. This allows solenoid circuit oil to move the converter clutch control valve against line pressure. With the converter clutch control valve in the apply position; regulated line oil, from the converter orifice control valve, is allowed to pass into the converter apply passage. It then flows through the turbine shaft to the apply side of the converter clutch. The regulated line oil, from the converter orifice control valve, controls the apply feel of the pressure plate.

As the pressure plate begins to move to its applied position, release oil on the front side of the pressure plate is redirected back between the turbine shaft and pump drive shaft and exhausted at the converter clutch control valve through an orifice, to time the clutch apply. When the converter clutch control valve moved to the apply position, orificed converter feed oil entered the converter to cooler passage to provide oil to the lubrication system.

SUMMARY
The forward and direct clutches are applied, the converter clutch is applied and the intermediate band is released; the transmission is in Drive (D) Range - Third Gear (direct drive).
