Overview The Sniper Transmission Controller (STC) is designed for common GM and Ford electronic 4-speed transmissions. Three part numbers cover a complete range of applications - all Sniper EFI systems, Sniper 2 EFI specific (M8 CAN connection), or a full standalone unit. The Sniper specific applications connect to your Sniper EFI system via CAN bus and is programmed through the existing Sniper 3.5-inch touchscreen. No programming is available with PC computer software, however the transmission functions can be data-logged and reviewed with Sniper PC software. The Standalone version includes a dedicated 3.5-inch touchscreen and is primarily intended for carbureted engine combinations. GM and Ford four speed electronic overdrive transmissions are simple in operation. They have four speeds with the top gear being an overdrive and all have a lockup torque converter that eliminates any slippage when the lockup is applied. With a stock torque converter the lockup should only be applied under light throttle conditions or excessive wear will occur. Upshifts, downshifts, and torque converter lockup are based on vehicle speed and throttle position (or optionally the MAP sensor) and are adjustable with the 3.5-inch touchscreen Features: Adds electronic transmission control functionality to a Sniper 1 Controls conventional electronic 4 speed transmission applications.
