Designed to activate the electrically controlled GM TH-400 downshift, this kit is required when replacing a TH-700 R4, TH-200, or TH-350 transmission having a cable-operated downshift mechanism. Universal in design, the switch can easily be adjusted to provide precise control of the downshift timing. Installation is simple, as it uses the stock, OEM bracketry. The kit includes a heavy duty 12 volt switch, actuator rod, spring, and a detailed instruction sheet.
