Either they haven't been reverse engineered, or they don't exist.

Well I took my truck to the transmission shop 2 day. They changed the
PC solenoid (pressure control), shift solenoid A and B. The problem is gone
I believe once the PCM went to FAULT mode it ignored the tables.

Thanx for the help, even though the help didn't fix it I have a MUCH better
understanding of the trans now.

Either the PCM did not command the PCS (i.e. zero current), or the PCS was open circuit (i.e. zero current)... either way, zero current means maximum pressure.

I read somewhere that once the PCM sees the circuit open (malfunction)
that it keeps the circuit open.
