U0100 code help

[mikebridson]

No, I mean drop out as if it goes into neutral. I guess what I was asking if anyone else had the U0100 code causing the trans to stop working? I've seen a few posts about U0100, but no one has posted a resolution to the problem. I work in a prototype engine lab and have 15 years experience working in shops and I have used forums before for help on unfamiliar issues. So, if anyone has had this code and resolved it, what did you do to fix it? I've replaced the controllers for the engine and trans, my next step is wiring harness. Batt and alternator are good, I've tested those. I've exhausted any problem I can think of besides the harness itself. I'm thinking maybe the CAN connections between the ECU and TCU are broken some where.
