OK. I am out of books etc. Maybe somebody has the auto wiring diagram.
If you measure resistance across the VSS, it should go On-OFF-On-Off etc when you turn the drive, not speed sensitive with a reed switch, so just turning it a bit will show you if it works. Then try to figure if that signal is getting to the ECU. I hear some have the trans control inside the ECU and some have a separate TCU.
The Hold is bothersome though, esp the only when hot part. The WSM gives pretty good step by step, but I don't have the autobox section.
