how about an answer, car @ trans shop i am out working, otherwise i would call. can trans tech call?
Expert:  Kenny Z. replied 10 days ago.

OK thanks, ***** ***** going to be the next piece of information I need, whether or not signal present at trans bulkhead connector for tcc solenoid. This will require a scanner that can command the solenoid on/off so that it can be monitored at the bulkhead connector with a meter.
