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

  The DSM Shift Box BASIC 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 low cost option is designed for those who donít need all the fancy features our other shift boxes offer, 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 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. Your choice of 4 colors for the LED 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 with the optional TCU package, OR use as a full standalone transmission shifter. Shift box includes a wiring harness with plugs for easy removal and an optional TCU bypass plug to allow the car to be drivable with the TCU if the shift box is removed without the need to unwire the shift box harness.

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