Another important item showed up today. My 2002 4L80e transmission. Complete, low mile out of a 2002 Chevy 3500. It will be controlled via a Microsquirt running the transmission control firmware and linked to the MS3x via the can network. This will allow full customization of shift points as well as dozens of other variables. The torque converter will most likely be a PTC matched to my combination.

Below is the Microsquirt powered transmission controller kit available from EFI Source.

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.
