11) Variable Bleed Solenoids
The transmission control unit uses variable bleed solenoids to regulate hydraulic pressure. This
hydraulic pressure controls torque flow through clutch elements within the transmission.
The TCU is able to vary the amount of torque applied to the clutch elements by controlling the
current to the variable bleed solenoid windings. The clutch element torque transfer is directly
related to the current applied to the solenoids.
During operation, the TCU evaluates the actual current delivered to the solenoid and compares
this against what is expected. If the current is not within predefined parameters, a DTC will be
set to indicate the load on the TCU is abnormal.
