Line Pressure Control
Transmission Line Pressure Control Wiring
Wiring Choose a pin which is capable of handling the current draw required for the Line Pressure Control Solenoid. See the workshop manual to determine the expected current draw. All Nexus DPOs are rated for 3 Amps, but some like the HBOs ...
Temperature Correction
Temperature Correction It is good practice to increase line pressures when the transmission exceeds rated temperature. Firstly, the increased temperature can cause greater than normal slippage within the transmission clutches, and secondly, any ...
Shifting Base Duty Cycle
Shifting Base Duty This sets the Base Duty Cycle of the Line Pressure when the Transmission Control function is shifting gears. If using Open Loop control: this is the duty cycle used. If using Closed Loop control: the PID control plus the result of ...
Shifting Target
Shifting Target Table This sets the target Line Pressure when the Transmission Control function is shifting between gears. If there is a base map available for your transmission, it is recommended to import the Target Pressure tables from there. If ...
In Gear Base Duty
In Gear Base Duty This sets the Base Duty Cycle of the Line Pressure when the Transmission Control function is holding the transmission in gear. If using Open Loop control: this is the duty cycle used. If using Closed Loop control: the PID control ...
In Gear Target
In Gear Target Table This sets the target Line Pressure when the Transmission Control function is holding the transmission in gear. If there is a base map available for your transmission, it is recommended to import the Target Pressure tables from ...
Line Pressure Control
Line Pressure Control Most automatic transmissions use pressurised transmission fluid to control which clutches and bands are engaged at any one time in order to select the desired gear. The fluid is typically pressurised by a pump which is turned by ...
