The Sniper Transmission Controller (STC) adds electronic transmission control to common Ford and GM electronic 4-speed transmissions. It covers Sniper EFI systems, Sniper 2 EFI (via M8 CAN connection), or a full standalone unit for carbureted engines. Upshifts, downshifts, and torque converter lockup are based on vehicle speed and throttle position (or optionally a MAP sensor), and are adjustable through a 3.5" touchscreen.
Specifications:
- Controls conventional electronic 4-speed transmission applications
- Tunes upshifts, downshifts, and wide-open throttle (WOT) shift points
- Full programmability of torque converter lockup
- Full tuning of transmission line pressure (shift firmness)
- Controls and layout interface mirror Dominator and Terminator X Max ECUs (except no paddle shift)
- Part Number: 551-100
This is a replacement/service unit only; the 3.5" handheld is not included but is available for purchase separately. A MAP sensor is needed if using MAP for line pressure, common on forced induction applications. Transmission harnesses are sold separately, and this product is not compatible with 4WD installations.
