DIYAutoTune has just released turn key transmission control packages for the 4L60E and 4L80E. These include a MicroSquirt control unit configured to run a transmission and a ready made wiring harness. The harness can plug into our existing MS3-Pro drop on harnesses using an included Amphenol AT connector. It integrates into the MS2 and MS3 line of engine management systems over CAN bus, or it can also run on its own if you feed it a tach and a throttle position signal. So whether you're using our engine management, someone else's, or a carburetor, this makes running a computer controlled automatic easy. Price is $499.
