What to decide before ordering

  • Your exact transmission model, generation and donor vehicle: GEN1 8HP45/70/90, GEN2 8HP50/75 or GEN3 8HP51/76.
  • Your current engine ECU and whether you want transmission-only or combined engine and transmission control.
  • The required TCU flashing, bypass-board installation or valve-body conversion.
  • Your shifter: factory BMW/Dodge, CAN keypad, paddles or sequential.
  • The harnesses, engine signals and calibration needed to complete the installation.

For a street car, aim for predictable shifts and smooth everyday driving. Send us your build details and the parts you already own so we can help complete your package.

Direct MaxxECU 8HP control applies to supported GEN1 transmissions. AWD, xDrive and transfer-case control require a separate integration plan.
