Advance Setup 2:
MAX SHIFT RPM:
The highest RPM you want your engine to reach during wide open throttle shifting can be
adjusted here.
LOWSPEED SHIFT:
This setting is used to adjust the vehicle speeds at which the transmission shifts under very
light load, i.e., when the TPS reading is small. A higher number means the transmission will shift at higher speeds.
NOTE: The handheld uses the setting entered here to perform calculations related to shift speeds. The results are
what actually get written to the TCU ( not this value setting itself ) Anytime you access this setting, it will display the
same default value to start. This is not an indication of a problem. The TCU does retain the shift speed information.
SHIFT AGGRESS:
This setting adjusts how aggressive the overall shift strategy is. A higher number means that
the transmission will hold gears longer and be quicker to downshift. This setting has a big impact on the overall
demeanor of the transmission.
SHIFT FIRMNESS:
This setting adjusts the base transmission line pressure. A higher number means higher
pressure which is felt as firmer shifts. Higher pressure also tends to allow less slip as the gears engage. Line
pressure automatically increases with increasing throttle and will always be maxed out during full throttle operation.
So line pressure does not need to be set uncomfortably high in normal part throttle driving in order to get full pressure
shifts under heavy load.
Keep in mind that the parts and techniques used in assembling a transmission can have a large effect on line
pressure and shift feel. Adjusting this setting will cause the TCU to call for more or less pressure. But it is possible
for the mechanical/hydraulic components of the transmission to overpower the control the electronics can have on
line pressure and shift feel.
