Not sure this matters to anything in this post. But I stumbled across this via the HPTuners knowledge base:
Force Motor
These values are the calibration of the transmission force motor (pressure control solenoid) versus desired line pressure and transmission temperature. The force motor is a relief valve that requires a current to reduce line pressure, the higher the current the lower the resulting line pressure. It is not recommended to change these values unless you have modified the transmission pressure control solenoid or are experiencing trans slip under heavy load. If you increase the Max Line Pressure constant, you may have to set the values in the 100 column to match (or be slightly lower) than the 96 column. Certain calibrations have to 100 column set to 1245ma (full line pressure bleed off).
- Force Motor Current vs. Commanded Line Pressure vs. Temp - Positive: This table determines how much current is applied to achieve the desired line pressure in relation to transmission temperature.
- Force Motor Current vs. Commanded Line Pressure vs. Temp - Negative: This table determines how much current is applied to achieve the desired line pressure in relation to transmission temperature.
Desired Shift Time
This is the desired shift time for each part throttle shift.
- Desired Shift Time vs. Torque - Normal: Normal Mode desired shift time (secs)
- Desired Shift Time - Normal: Normal Mode desired shift time
- Desired Shift Time Adder- Normal: Normal Mode desired shift time adder
- Desired Shift Time vs. Torque - Performance: Performance Mode desired shift time (secs)
- Desired Shift Time - Performance: Performance(Tow/Haul) Mode desired shift time
- Desired Shift Time Adder- Performance: Performance Mode(Tow/Haul) desired shift time adder
TUTD
- TUTD Mode Select: Enable/disable TUTD feature.
- TUTD Type: Selects the method used to wire the TUTD switch
- TUTD IP Display: Enable/disable the TUTD mode display
- TUTD UpDown Enable Req: Enable/disable the requirement for an up/down request and a mode request to enable TUTD
- TUTD Hold Shift Enable: Enable/disable a shift to occur if the driver is holding down the TUTD switch
- TUTD Mountain Mode: Enable/disable powertrain braking the TUTD downshifts, when in D3
- TUTD Range Select: Enable range select TUTD mode activation, otherwise use state of TUTD switch
- TUTD Range Select Gear: When range select TUTD mode is enabled this selector position enables TUTD mode
Shift Pressure
These tables define the desired transmission line pressure in relation to input torque and current gear. These tables are used to modify your transmission shift pressures.
- Base Shift Pressure vs. Torque vs. Gear - Normal: Normal Mode Desired Shift pressure. Table returns the pressure offset to be used on the Force Motor Current table axis. Increasing these values firms the shift. Value range is from 0 to 96
- Base Shift Pressure vs. Torque vs. Gear - Performance: Performance Mode Desired Shift pressure. Table returns the pressure offset to be used on the Force Motor Current table axis. Increasing these values firms the shift. Value range is from 0 to 96
- Brake Shift Pressure vs. Torque vs. Gear: During a manual downshift using the gear selector, this alternate table is used to modify the line pressure. If this table is not in use, the Engine Braking downshift will be taken from the base shift pressure table(s). Table returns the pressure offset to be used on the Force Motor Current table axis. Increasing these values firms the manual downshift.
- Max Line Pressure: This is the maximum desired line pressure allowed. It is a clamp for any shift table value and has the final say on the line pressure offset before it is used on the Force Motor Current table.
Shift Pressure Modifier
- Upshift and Downshift Pressure Modifier: These tables are a modifier to the returned base shift pressure tables. It increases/decreases the pressure by adding positive or negative pressure depending on torque and trans temperature. Increasing these with a positive values firm the shift. Zero has no effect.
- Upshift Pressure Modifier Mult vs. Temp vs. Gear: An optional table multiplier to the returned base shift pressure tables. It increases/decreases the pressure depending on shift and trans temperature. Increasing the multiplier firm the shift. 1= no change.
Shift Pressure Adapt
- Upshift Adapt: Master enable/disable for upshift pressure adapt
- Downshift Adapt: Master enable/disable for WOT(detent) downshift pressure adapt
