5.3/4l60e swap Trans codes, Please help!!
P0740 - TCC ENABLED SOLENOID CIRCUIT
P0785 - 3-2 SHIFT SOLENOID CIRCUIT
P1860 - TCC PWM SOLENOID CIRCUIT
I know that the correct wires are just plain not hooked up. Can anyone point me in a direction to find exactly which wires need to be hooked up to make the trans operate correctly.
Is there is a down and dirty guide to wiring up these trans.?
Thanks for any input!

It just does not include the TCC PWM "feel" solenoid.
I understand that the solenoids are grounded to activate but that's sent from the PCM which should not need to be rewired since it's all stock harnesses I'm dealing with.
I guess I just don't what to test next other than grounding the solenoids and see if they activate.
Knowing that I found pin 75 gets powered from IGN 0. Looking at the back of the fuse block IGN 0 relay is getting energized but only has one wire coming out of the back for its ground.
My question is where does IGN 0 feed power to the VCM, does anyone have a diagram of that?
