Start with all of your grounds. Invest in a PowerProbe and learn how to use it, if you use it wrong you could blow your ECM or any of the modules.

The codes that come back, are the P 0118. The scan tool used was a very good one, not sure though, as it’s not mine. I’ll post it when I find out. And it’s acting like it’s the solenoids. It has a problem communicating with second gear. It will shift down into first, or sometimes not want to shift into second
