I cant get converter lock in my car , 4l60e trans. I have checked the wiring more than once, changed transmissions, tried to bypass the computer for the tcc solenoid ( it has two one is pwm the other is not) rwd pcm's its pin 22 tcc sol control and pin 28 tcc enable sol control. gtp is missing one in the diagram

In reading up on topics similar to mine either a write entire or another pcm is necessary, but want to be sure i believe the gtp pcm cant control the tcc solenoid but dose control the pwm one

97 gtp 3800 motor
99 3800 firebird 4l60e trans
97 gtp computer #16227797
