Holley 551-101 Sniper 1 Transmission Control Kit

Handheld not included

Part Number: 551-101

The Sniper 1 Transmission Controller (STC) allows the use of common Ford and GM electronic four speed transmissions. It connects to your Sniper EFI system via CAN bus and is programmed through the existing Sniper 3.5” touchscreen (not included). No programming is available with PC computer software, but the transmission functions can be data logged and reviewed with Sniper PC software. This kit is intended to work with Sniper throttle body injection systems only as it contains the Sniper Transmission Control Module as well as the Power/CAN bus harness.

Features and Benefits

• Adds electronic transmission control functionality to a Sniper 1 system
• Tune upshifts, downshifts and wide open throttle (WOT) shift points
• Full programmability of torque converter lockup
• Full tuning of transmission line pressure (shift firmness)

Requires Sniper Version 2 ECU and up to date handheld firmware, handheld is not included but available for purchase. A MAP sensor is needed if using MAP for line pressure, commonly on forced induction applications. Harnesses for controlling electronic 4 speed transmissions are sold separately, but this product is not compatible with 4WD installations.
