Forced Four SMART 75
INSTALLATION INSTRUCTIONS
-
If used with a TCU or other method of controlling the
transmission, only one way of controlling the transmission
should be powered on at one time to prevent unexpected
control of the transmission or damage to the TCU. Use of our
TCU package or similar suitable switch/relay must be used to
power the TCU or shift box one at a time.
-
Use of diodes, provided with the TCU package, is necessary
to prevent damage to TCU.
-
The SMART 75 must be properly configured for your
transmission type before operating
-
Mount the SMART 75 unit in the vehicle cabin away from heat
and moisture, routing wires away from a CDI ignition box or
high voltage coil wiring recommended to prevent erratic
behavior.
Wiring the SMART 75 shift box:
Any wires not used should be capped to prevent damage or
unwanted behavior!

General Usage Instructions:
-
Once installed, this shift box is simple to use. Simply
press the up-shift button to advance to the next gear, or
press the down-shift button to drop to a lower gear.
-
This shift box will boot up in 2nd gear, unless configured
differently by the user, every time as a safety in case the
shift box would ever reboot due to a power connection
problem.
-
By default the downshift protection RPM is 4500RPM, see the
menu below to change this, or disable the downshift
protection.
-
To use the RPM up-shift feature, you must set the shift
points to your desired RPM in the menu. Set the shift point
~1000RPM sooner than you want the shift to be made to start,
and adjust as necessary. This is due to the delay inside the
transmission to engage the clutches. You must enable the
UP-SHIFTER in the menu to use this feature.
-
The overdrive off feature can be used by up-shifting to
overdrive gear. Press and hold the up button until the O/D
off LED illuminates and the shift box downshifts to the next
lower gear. To turn O/D back on, up-shift to the max gear
and press and hold the up button until the O/D off LED turns
off and the shift box up-shifts to overdrive gear.
-
The torque converter lock-up feature, when enabled, will
illuminate the green LED when the solenoid is turned on
-
Note that the shifts are made at full line pressure,
learning the timing on when to make the shift will make
using this shift box much more pleasurable on the street.
-
