Fluid Pressure Sensor/Switch: Description and Operation
Variable Line Pressure Sensor - Operation
OPERATION
The TCM calculates the desired line pressure based upon inputs from the transmission and engine. The TCM calculates the torque input to the
transmission and uses that information as the primary input to the calculation. The line pressure is set to a predetermined value during shifts, to ensure
consistent shift quality. During all other operation, the desired line pressure value is adjusted based on torque level and other transmission requirements.
