Overdrive and Lock-Up Kit for Chrysler

The COMPUSHIFT Mini Overdrive and Torque Converter Lock-Up Kit for Chrysler is a standalone plug-and-play system designed to control the torque converter clutch lockup and the overdrive on Chrysler A500/42RH, A518/46RH and 618/47RH transmissions. The system uses a miniaturized version of the same control software and electronics as the COMPUSHIFT Sport. 

The COMPUSHIFT Mini Overdrive and Torque Converter Lock-Up Kit for Chrysler can be programmed by App on your Smart Device using Bluetooth!

The kit ships with all of the parts that should be needed for the installation including COMPUSHIFT Mini Lock-Up Controller, wiring harness, speed sensor and fittings,  hook and loop fasteners, terminals and cable ties.  An "AccuLink" throttle position sensor will be included if you selected Carburetor as your engine type.

COMPUSHIFT Mini Overdrive and Torque Converter Lock-Up Kit Harness for Chrysler

A free downloadable App allows the user to adjust and tune for their specific application and diagnose problems should they occur. The easy to read app screens can display current vehicle speed, throttle position, transmission pressure, 4th gear/overdrive activity, torque converter clutch engagement (lockup), and allow for further custom tuning. This torque converter lock-up controller kit 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.  Properly tuned, your vehicle should have better gas mileage during cruising, and be more responsive to the throttle.

The COMPUSHIFT Mini is IP rated. It also offers CAN bus support.

Teran Marsell

Went from the worst shifting transmission in any car I own, to amazing. The control of the Speeds, lockup, and 3-4 shift makes this 47rh behind the 12 valve pleasureable to drive.

That's great to hear Teran. So glad to hear your transmission is shifting a lot better now!
