(1) Power flow - Drive 4 lock up
In Drive 4 Lock Up, transmission drive is the same as for Drive 4 but with the application of the
converter lock up clutch to provide positive no-slip converter drive.
(2) Control
To maintain this arrangement in the steady state solenoids and valves are activated as
follows :
- When S7 is switched ON, S7 feed oil to the converter clutch control valve is switched OFF
and allowed to exhaust through the S7 solenoid. This allows the valve to move to the
clutch engage position.
- Regulated apply feed oil, drived from drive oil at the converter clutch regulator valve, is
directed by the converter clutch control valve to the engage side of the converter clutch.
- Converter clutch release oil is exhausted at the converter clutch control valve.
- Converter feed oil is re-routed by the converter clutch control valve directly to the oil cooler
and lubrication circuit.
