Repair Manual
Solenoids SV3, 5, 9 and 10 are Normally Applied, which applies their assigned component when they are Off. They are
Energized (On) to release their assigned component. These solenoids are also Modulated, to control their assigned
component apply and release rates. Consult the charts above to compare the amperage to clutch application.
Solenoid SV6 (N93) is modulated based on engine load to control main line pressure. Amperage will decrease to increase
main line pressure.
Solenoid SV4 (N91) is modulated to control Torque Converter Clutch (TCC) apply and release rates, but dependends on the
SV2 (N89) solenoid to be On to stroke the TCC switch valve so that N91 can complete its assigned task. There will be situations
during Manual Tiptronic shifts, SV4 (N91) amperage will indicate .500 - .700 amps and the TCC will be Off, as SV2 (N89) is
"0" which indicates Off.
T = On in Tiptronic Mode
