COMPUSHIFT Mini for Chrysler A518/46RH and Chrysler A618/47RH


The COMPUSHIFT Mini is a standalone plug-and-play system designed to control the torque converter clutch and overdrive on Chrysler A518/46RH and Chrylser A618/47RH transmissions.  The system uses a miniaturized version of the same control software and electronics as the COMPUSHIFT II.

A built-in display and keypad lets the user adjust and tune for their specific application and diagnose problems should they occur. The easy to read screen can display current vehicle speed, throttle position, transmission pressure, 4th gear/overdrive activity, torque converter clutch engagement, and allow for further custom tuning.  The controller can can drive an electronic speedometer as well.

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

Installing the COMPUSHIFT Mini is a straightforward operation if you are familiar with working on cars. No special considerations are needed when driving with the COMPUSHIFT Mini. Once tuning is complete, the COMPUSHIFT Mini can be mounted in its final location and left alone. No further adjustment or maintenance is needed.  Properly tuned, your vehicle should have better gas mileage during cruising, and be more responsive to the throttle.

The kit ships with all of the parts that should be needed for the installation including COMPUSHIFT Mini Controller with keypad, wiring harness, speed sensor and fittings, hydraulic pressure sensor, hook and loop fasteners, terminals and cable ties.
