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

This revolutionary shift box is designed to be used like a standard handheld shift box for shifting gears. It can alternatively be used with external shifters. Our shift boxes are compatible with all 89-99 vehicles utilizing an F4A32, F4A33, W4A32, and W4A33 automatic transmission. This shift box has features that others don’t come with, including our exclusive down shift protection to prevent the user from accidentally down shifting when the engine revs are above a user definable RPM. This shift box will beep to let you know a shift was blocked. This shift box has a full color graphic display and is completely programmable for up-shifts at user definable RPM on the fly in the car. This allows the user to set exactly what RPM each up-shift will be made. Note that in some cases the wiring may need to be lengthened during installation to suit your individual setup, the included wiring harness is 5' in length. Professional installation of this Shift Box is recommended!
