On the other hand, RPM is very important for a transmission controller. You never want to allow a downshift if your RPM is high and the downshift will cause the engine to over rev (aka "Money Shift").

I know this may be an old thread, but thought I'd comment anyway. Actually, RPM is pretty easy to get. Just use the LS coil signal as input instead of a VSS sensor. It's a 5V square wave. But RPM is not a good driver for Line pressure. Instead, consider using the MAP sensor or the Pedal sensor.

Patracy, you had a thread on arduino forums that I was going to comment on, but it's locked. Hope you made some progress. I've built an arduino 4l80e controller and enhanced it over the last 6 years. Mine is feature rich and has been working flawlessly for years and thousands of miles...
