Shift Box DSM BASIC2 - Product Support Page
Last updated 9/26/15


Basic 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 3rd gear 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 begin using this feature.

  • The overdrive off feature can be used by up-shifting to 4th gear. Press and hold the up button until the O/D off LED illuminates and the shift box downshifts to 3rd gear. To turn O/D back on, up-shift to 3rd gear and press and hold the up button until the O/D off LED turns off and the shift box up-shifts to 4th 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, so learning the timing on when to make the shift will make using this shift box much more pleasurable on the street.


Using the menu:

        To enter the menu:

o   Downshift to 1st gear then press and hold down shift button until menu opens

        Basic tips for easier navigation:    

o   Default values are shown as underlined

o   Bold text is word for word what the shift box will display

o   You can skip to the next menu option without waiting for the text to be displayed

o   Wide open throttle will toggle some values the opposite direction (requires TPS wire connected)

o   Up button selects or toggles a item/value, down button advances to the next menu item

o   Menu will automatically save settings and exit after a few seconds of user inactivity

2-3-UP-SHIFT-RPM = 6500 (Set the 2-3 shift point, configurable from 5000-12000RPM)
3-4-UP-SHIFT-RPM = 6500 (Set the 3-4 shift point, configurable from 5000-12000RPM)
DEBOUNCE-UPSHIFT = 500 (Delay after auto up-shifts to prevent double shifts, configurable from 500-1500 in 50ms steps, 500=default)
LOCK-UP-FIRST = 00 (Default is OFF (00), Configure minimum lock-up RPM or disable 1800-5500RPM)
LOCK-UP-SECOND = 3000
(Default is 3000RPM, Configure minimum lock-up RPM or disable 1800-5500RPM)

(Default is 3000RPM, Configure minimum lock-up RPM or disable 1800-5500RPM)
LOCK-UP-FOURTH = 3000
(Default is 3000RPM, Configure minimum lock-up RPM or disable 1800-5500RPM)
PULSE PER REV = 2
(Set the number of pulse per engine revolution - 4 cylinder=2, 6 cylinder=3, 8 cylinder=4, default=2)
RESTORE DEFAULTS? (Up button to restore factory default configuration)
                CONFIRM RESTORE DEFAULTS? (Up button to confirm the restore defaults)
DISPLAY RPM (Up button displays current engine RPM, useful for verifying proper installation)
ABOUT? (Up button displays current software version and product web site address)
SAVE AND EXIT? (Up button to save and exit, down will advance back to the first menu option)

*
All settings are saved to flash memory as soon as the menu is exited, automatically

Updating the firmware / warranty:

  • The most recent DSM Shift Box BASIC2 firmware version is 001
  • Do not remove the serial number sticker from the back of the shift box as this will be needed for any warranty claims
  • Please send an e-mail to sales@forcedfour.com to inquire about updating your firmware or to make a warranty claim
  • (Note: All settings will be set to factory defaults when the firmware is updated)

Wiring instructions:

  • IMPORTANT NOTE: If used with a TCU or other method of controlling the transmission, follow the instructions closely. 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 the supplied switch to switch between transmission controls or substitute a suitable relay.

  • Use of diodes, provided with the TCU package, is necessary to prevent damage to TCU.

  • If the transmission shifts from 1st to 4th to 3rd to 2nd, then the shift solenoid wires are reversed


 

Using the DSM Shift Box BASIC2 as a standalone transmission controller:
Bold print is required for normal operation, others depend on usage and vehicle options

  • Red wire is +12 volt power from the ignition switch

  • Black wire is ground, connect to a good clean chassis ground

  • White wire splices with the crank sensor signal or tachometer signal

  • Yellow wire goes to the Shift Solenoid A

  • Brown wire goes to the Shift Solenoid B

  • Orange wire goes to Converter Lock-Up Solenoid

  • Green wire is the TPS signal, attach near ECU or TCU

  • White/Green wire is the brake switch signal, attach to brake switch active when +12V

  • Purple wire is the up-shift button (short to ground to perform up-shift)

  • White/Purple wire is the down-shift button (short ground to perform down-shift)

  • Any remaining wires should be capped


 

Using the DSM Shift Box BASIC2 with TCU or other transmission controller:
Bold print is required for normal operation, others depend on usage and vehicle options

  • Red wire is +12 volt power from the ignition switch, connect as follows using switch harness
    * NOTE: On the fuse block there are 2 wires from the TCU fuse, both must be cut and spliced together through the supplied switch harness to prevent the TCU from being powered when the shift box is being used.
         Red wire (shift box) to Green wire (switch harness)
         Yellow wire (switch harness) to fuse vehicle harness (Power from TCU fuse)
         Brown wire (switch harness) to fuse block harness (This will power the TCU)
     

  • Red wire is +12 volt power from the ignition switch

  • Black wire is ground, connect to a good clean chassis ground

  • White wire splices with the crank sensor signal or tachometer signal

  • Yellow wire goes to the Shift Solenoid A (TCU must connect to solenoid through required diode)

  • Brown wire goes to the Shift Solenoid B (TCU must connect to solenoid through required diode)

  • Orange wire goes to Converter Lock-Up Solenoid (TCU must connect to solenoid through required diode)

  • Green wire is the TPS signal, attach near ECU or TCU

  • White/Green wire is the brake switch signal, attach to brake switch active when +12V

  • Purple wire is the up-shift button (short to ground to perform up-shift)

  • White/Purple wire is the down-shift button (short ground to perform down-shift)

  • Any remaining wires should be capped
     

        TCU solenoid outputs connect to white/yellow side of diode included with TCU package

Shift solenoid and shift box solenoid output connect to yellow side of diode
 


Updating the firmware:

  • The most recent Shift Box PLUS firmware version is 001
  • Please send an e-mail to sales@forcedfour.com to inquire about updating your firmware. Please note this shift box does not support USB firmware updates and will need to be shipped to Forced Four to be updated.
  • (Note: All settings will be set to factory defaults when the firmware is updated)
