Automatic Transmission - Ford Falcon 6 Speed
The Automatic Transmission - Ford Falcon 6 Speed Function supports the ZF 6HP26 6-Speed Transmission found in the BF and FG Series Falcons.
The ZF Transmission Control Module (TCM) uses the vehicle's CAN bus to transmit engine torque limits and reduction requests to the ECU during operation. Torque limits must be obeyed, as excessive torque can cause damage to transmission components.
This function also allows for shift point tuning.
NOTE: The Torque Model Function must also be enabled for control of the ZF 6-Speed Transmission, as
the ZF TCM requires the engine torque figures to determine the internal line pressures, and both functions
work together to identify and apply torque reductions when required.

Options
The following settings should remain as 'CAN Input' to ensure correct operation of the Ford Falcon 6 Speed Automatic Transmission.
Transmission Torque Reduction Source
Select from the following:
Disable
Disables the transmission torque reduction source
CAN Input
Enables the transmission torque reduction source input. This input is a message transmitted via CAN to the ECU from the Transmission Control Module, requesting a torque reduction.
Transmission Torque Limit Source
Disable
Disables the transmission torque limit source
CAN Input
Enables the transmission torque limit source input. This message is transmitted via CAN to the ECU from the Transmission Control Module. This information is important in ensuring safe operation of the Transmission.
Setting up Tables
Shift Point Load
Under ECU Navigator>Automatic Transmission - Ford Falcon 6 Speed>select Shift Point Load
Axis selection and changing values
The horizontal axis (left to right) is fixed to Engine Demand to make sure the Transmission shifts under the correct circumstances. Changing the axis values can be accomplished by pressing F3 when the table is selected, then either editing an existing value or adding a new value. Note that if you edit an axis site value, the overall table values will be adjusted so that the shape of the table is unchanged.
Engine Demand is a non-linear indicator of how much torque is being requested from the engine. It is closely related to throttle and pedal positions.
Tuning
The purpose of this table is for tuning shift points. The output value of this table (shift point load %) is used as the load axis for the shift point calculations within the Transmission Control Module. Automatic shifting during cruise control is heavily influenced by the tuning of this table.
As a general rule, increasing the values in the table will cause the shift point to occur at a higher RPM. This can make the car feel sportier, but may be worse for fuel economy. It is recommended that the table begins with 0% and ends with 100%.
