I'll have to figure out some logic offline... I'll get back to you later.

ok thanks
I tried grounding pins N P R on the trans connector and with nothing grounded it says gear 2 and tcc off due to range is yes. Grounding any other combo only yeild a gear 3 and a tcc off due to downshift is yes but tcc off due to range is no.
You want pins R (C2-17) and P (C2-18) both grounded when in D.
See: Manual Valve Logic and TFP.pdf.
This is the opposite to the P/N switch; you can use a relay to obtain an inverted signal from the P/N switch to feed to R and P.

could the tcc off due to downshift be yes since i am testing with the car not mving...vss=0?
Try grounding just pins R (C2-17) and P (C2-18)... this makes the PCM see that manual valve is in D4 position.
Leave pin N (C2-63) un-grounded.

Try this, and go for a test drive...
could put car on jackstands and test drive it like this, but keep the speed below 55-60 mph
(unloaded tire can accelerate up to high speed too quick and explode, I'm sure you know the usual warnings).
Went for a test drive. As soon as I stat moving all the Tstate09 flags go to NO but the gear PID changes from 3 to 1 so its thinks I am stuck in 1st? No lockup.
Looking at trouble code P1810 which is a valve switch malfunction. It will assume D4 and enable the TCC lockup inn commanded 4th gear? I will turn on P1810 process enablers and see what happens....
