Hey Chip,
You are in the automotive electronics industry right? Do you know of any good references to the controls / diagnostics information and any embedded controller designs for the 4L60E / 4L80E trannys?
I have a controller designed now for ignition and fuel injection control and would like to get some info on the digital interface to these trannys so I can program different shift patterns depending on whether I want cadillac behavior or fire breathing drag strip behavior.
