TH400 electronic kickdown

My TH400 uses a solenoid to kickdown instead of the linkage method. Since this is controlled by the ECM (instead of TCC control) it needed new settings. RBob quickly responded with the following config which is working great. Posted here just to keep my notes together.
=========================================
What is interesting is that GM sets up the TH400 kick down calibration to use a set TPS%. Not based on MPH or RPM, just set to 85% in the case of ABHC. The thresholds are set up as the coast or decel TPS% unlock. Unlock (no kickdown) when the TPS% is less then the coast value. Then lock (do kickdown) when the TPS% is above the coast value.
So with that, this is what I found works for the TH400 kickdown (all TCC parameters). This is only bench tested, but looks OK:
Set Lock enable CTS to -40C
Set TPS% opening/closing deltas for unlock to 100% Set Relock delays to 0 (all) Set Forced Lock to 255 MPH
Set the 4 TCC TPS% unlock/lock tables to 255:
LoGr TPS% to Stay Unlocked
LoGr TPS% to Unlock
HiGr TPS% to Stay Unlocked
HiGr TPS% to Unlock
Set the 4 MPH thresholds to 0:
LoGr MPH OK to Lock
LoGr MPH to Unlock
HiGr MPH OK to Lock
HiGr MPH to Unlock
Set these 2 coast values to 85%:
LoGr Max TPS% coast unlock
HiGr Max TPS% coast unlock
Set these 2 coast values lower for hysterisis (probably mispelled), at 75%:
LoGr Min TPS% coast unlock
HiGr Min TPS% coast unlock
With these settings the TCC ECM output will go low when the TPS% is greater then 85%. The Relay is set up to provide +12 volts to the downshift solenoid whenever the TCC ECM output goes low (grounded).
