Thanks for purchasing and installing the COMPUSHIFT Mini.

If you want to get started quickly, please read the COMPUSHIFT Mini Quick Install Guide.

The COMPUSHIFT Mini is a standalone plug-and-play system designed to control the torque converter clutch and overdrive on selected transmissions including:

  • GM 700R4
  • GM 2004R
  • Chrysler A518 / 46RH
  • Chrylser A618 / 47RH

Unlike other control modules that use vacuum switches or a simple delay timer, the COMPUSHIFT Mini uses throttle position and vehicle speed to optimize its shifting and clutch control.

A built-in display and keypad lets the user adjust and tune for their specific application, and diagnose problems should they occur.

The COMPUSHIFT Mini uses a miniaturized version of same control software and electronics as HGM's COMPUSHIFT II.
