Our shift boxes are designed to simplify manual shifting of your auto DSM

  The Shift Box DSM-PLUS is a simple to use automatic transmission handheld shift box designed for automatic DSMís. Our shift boxes are compatible with all 89-99 vehicles utilizing an F4A32, F4A33, W4A32, and W4A33 automatic transmission. This programmable low cost option is designed for those who donít need all the fancy features of our Shift Box COLOR, but still want the same great quality our products all have. This shift box has all the same features most competitor shift boxes include plus a few features there's don't, all this for a lower price. This Shift Box is programmable for automatic up-shifts, just like the COLOR. This allows you to set the RPM for each gear change which is a useful feature for drag racing. This shift box also includes our exclusive down shift protection to prevent the user from accidentally down shifting when the engine revs are above a user adjustable RPM. This shift box will beep to let you know when a shift was blocked if over your configured down-shift protection RPM. Available with a red LED dot matrix display, high quality up shift and down shift buttons, easy to wire, works with your TCU or as a full standalone, and has inputs for external shifters. You can even switch between your TCU and this shift box without going into limp mode using the optional TCU package, OR use as a full standalone transmission shifter. Shift box includes a wiring harness that requires a direct wired connection.

Optional TCU package includes a toggle switch with wiring harness, only necessary if you plan to use with a TCU in the car.
