Shift Defuel Setting
With this option the amount of fuel delivered to the engine during the shift
point is reduced—thus decreasing torque during the shift point. This will
cause less wear on the transmission—and result in overall improved
drivability.
Transmission Setup Option Descriptions
Defueling at locked (when the torque converter is locked) shift points
reduces the torque output by the engine and allows the torque converter
clutch to lock after the shift.
Defuel all locked shifts
With this option, when the torque converter is locked the amount of fuel at
the shift point is reduced—thus decreasing torque during the shift point and
allowing the torque converter clutch to lock. This will cause less wear on
the transmission—and result in overall improved drivability.
Defuel 4-5 locked shift
This option provides a decrease in torque output at the shift point between
gears 4 and 5, thus decreasing torque during the shift point and allowing the
torque converter clutch to lock. This will cause less wear on the
transmission—and result in overall improved drivability.
No defuel on shifts
This option provides no decrease in fuel during shift points. Power will be
delivered throughout all of the shift points resulting in quicker more
responsive shifting.
