Description

The Holley Sniper 2 EFI Transmission Controller is a dedicated standalone module designed to manage automatic transmission operation in EFI-equipped engine swaps and performance builds. This controller handles transmission logic independently, eliminating the need for factory PCM integration and providing direct control over shift timing, torque management, and line pressure across 4L60, 4L70, 4L80E, AODE, and 4R70W transmissions. It's engineered for builders who demand precision electronic control without factory constraints.

The Sniper 2 platform operates as a fully programmable transmission controller, interpreting engine speed, load, throttle position, and vehicle speed to execute shift schedules tailored to your specific application. This approach is particularly valuable in engine swap scenarios where original transmission electronics are incompatible with the donor powertrain. The controller communicates with the engine management system to coordinate shift points with ignition timing and fuel delivery, ensuring smooth transitions and maximizing drivability. Adjustable parameters allow fine-tuning of shift firmness, converter lock timing, and failsafe behavior without expensive tuning software.

This standalone transmission controller is ideal for LS swaps, crate engine installations, and vintage vehicle restorations where OEM transmission wiring and logic don't align with the modern powerplant. Street rodders, off-road builders, and performance enthusiasts benefit from the flexibility to dial in shift characteristics that match engine output and driving dynamics. Installation requires integration with an EFI engine computer capable of providing speed and load signals, making it compatible with most contemporary standalone EFI systems and modern engine controllers.
