    The Sniper 1 Transmission Control Kit (STC) adds electronic control of common Ford and GM electronic four-speed transmissions to a Sniper 1 EFI system. It connects via CAN bus and is programmed through the existing Sniper 3.5" touchscreen (sold separately); transmission functions can also be data-logged and reviewed using Sniper PC software.

    Specifications:

    • Application: Sniper 1
    • Part Type: Automatic Transmission Control Module
    • Part Number: 551-101

    Requires a Sniper Version 2 ECU and up-to-date handheld firmware (handheld sold separately). A MAP sensor is needed if using MAP for line pressure, common on forced-induction applications. This kit is intended for Sniper throttle body systems only and is not compatible with 4WD installations; harnesses for controlling electronic 4-speed transmissions are sold separately.
