VX RAIL CONTROLLERS

What is the RAD Designs Rail Controller? The RAD Designs Rail Controller is a precision-built electronic shift controller designed for automatic transmissions, providing complete manual control over gear selection. It works seamlessly with electronically controlled transmissions, enabling precise, on-demand shifting. You do not need a TCM to use the Rail Controller, but you can wire it in with switches to retain your automatics shifting features if you still have the TCM system in your vehicle. The controller body is 3/4" thick x 3" long x 2" tall. There are stops for each gear up and down shifting.
