Key Features

Replacement/service unit only, handheld is not included but available for purchase. A MAP sensor is needed if using MAP for line pressure, commonly on forced induction applications. Transmissions harnesses sold separately, but this product is not compatib

The Sniper Transmission Controller (STC) is designed for common Ford and GM electronic 4 speed transmissions. This covers a complete range of applications, for 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 (not included). 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 is primarily intended for carbureted engine combinations. Ford and GM 4 speed electronic overdrive transmissions have 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 a 3.5-inch touchscreen (not included).
