Add GM 6L80/90E transmission control to any existing vehicle utilizing a Terminator X Max ECU. A departure from traditional Holley EFI transmission control, the Terminator X Max ECU allows the ability to use 2007+ GM 6L80E and 6L90E transmissions by communicating via CAN with the internal TCM (Transmission Control Module). The supplied Holley EFI OBDII transmission tuning hand-held is used to adjust shift points, tire size and gear ratio. Terminator X V3 software provides the ability to dial in torque management to optimize the desired shifting characteristics when using a 6L80/90E transmission. The software also enables you to control the secondary shift mode within the transmission TCM and allows use of tap Up/Down shifting.

Within Terminator X V3 PC Software:
--- Virtual Torque Management Tables
--- Virtual TPS Tables to dial in shift characteristics regardless of engine
--- DBW and Timing torque reduction tables to create smooth shifts

Within the Holley EFI OBDII Transmission Tuning Hand-held:
--- Ability to read and clear TCM fault codes
--- Ability to raise and lower shift points by MPH or RPM
--- Support for Tap Up/Tap Down & Transmission's Secondary Shift Mode

If you currently have a Terminator X ECU, upgrading to a Terminator X Max ECU can be easily done by plugging your main harness into the Max ECU and re uploading your existing calibration.

Holley Terminator X MAX GM 6L80/90 transmission kit features:

* Included TCM hand-held tuner with integrated wizard is required for setup in conjunction with the Terminator X 3.5 in. hand-held. Terminator X V3 software unlocks optional tuning parameters.
* Plug-and-play with any engine controlled by a Terminator X Max ECU
* Supports: Shift Mode - Tap Up / Tap Down, and torque management
* Four loose wires:
--- Power (Red): Supplies power to the transmission solenoids. This should be connected directly to the battery, or a constant battery source capable of supplying 5 amps
--- Ground (Black): Connect to a good chassis/engine ground source
--- Brake Switch (Light Blue/White): Wired to the brake light switch. This must be installed to a +12 V source (as most brake light switches are)
--- Park/Neutral Safety (Yellow): Circuit for starter solenoid. When the transmission is in Park or Neutral, this yellow wire will be grounded (-). When the transmission is in gear this circuit will be open.
