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

  The Shift Box DSM-PLUS2 is a simple to use automatic transmission handheld shift box designed for automatic DSM’s. 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 don’t need all the fancy features of our SMART Shift Box's, but still want the same great quality our products all have. This Shift Box is programmable for automatic up-shifts. This allows you to set the RPM or MPH for each gear change which is a useful feature for drag racing. 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. Available with a red or blue LED .7" 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. This shift box is a handheld device with all components contained in the very small handheld device. Shift box includes a wiring harness with plug for easy removal.

Our innovative features may have been copied by our competitors, but we still offer a better working, higher quality product with features they can't provide no matter how much they attempt to copy, all with excellent support at an awesome price.

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