Me and my father are putting together 2 projects involving 2 4L80E transmissions. Im not an expert at code or even arduino but we just purchased 2 arduino 256 boards and 2 sets of 4 channel relays. We have several miscellaneous components to go with these. I have had success in programming other automated programs in the past. Maybe i can help share your work load with the 4L80E side of your programming? I know I have to use PWM on the pressure solenoid and i know which frequencies to use. Some code to start with getting me in the right direction for automatic shifting and how you use the map sensor in conjunction would be the biggest hurdle for me. It would be real nice for us to not have to use our toggle switches anymore lol. Maybe we can help each other out?
