Transmission swap??
OK, I placed a temporary wire from the transmission connector to the PCM and still nothing. (still utilizing transmission & PCM connectors)
I will move forward with replacing the 20 pin transmission connector as I have it and other than the PCM connection point I'm out of ideas / options.

Per the schematic, back probe the 1-2 shift solenoid GROUND (A-LGT GREEN) and OHM it to chassis ground when in PARK and in drive. This will test if the PCM is actually grounding that circuit.
OK, here is what I found.
If car is off (completely no key in ignition) I read 25 ohms to ground, from under dash near PCM.
If car is running the circuit is open, no mater where (PNRD21)
Should be the following:
P = ON
R = ON
N = ON
1 = ON
2 = OFF
3 = OFF
4 = ON
What'* the next diagnostic / test? Does this point toward the PCM??

Car is very sluggish until it gets to around 10-15 mph, shifts once (2nd to 3rd) and then at speed it runs around 2200Rpm.
When manually selecting the gear, 1-2 makes no difference & 3-4 makes no difference at speed.
