MicroSquirt Trans control for 4L80 & 4L60 Transmissions

The MicroSquirt transmission control system gives laptop tunable electronic control over shift points, converter lockup and line pressure for GM 4L60 & 4L80 transmission.

This product is configured for MegaSquirt products with CAN capability such as the MicroSquirt and MS3 Gold box. The unit comes loaded with the proper firmware and a base startup program for the 4L80 transmission. Additional tuning may be required for your application.  The CAN network is required for sensor sharing between the Engine and Transmission controllers.
