Eliminate the temp switch & wire it exactly like your second picture shows!!
Tech Tip....Take the Lead with the Black wires off the Temp Switch & Connect it to the 4th gear pressure switch. Cut out the other (Green/Tan) Temp Switch Lead.
Before you put the pan back on.....Test the TCC solenoid & 4th Pressure switch if you haven't already.

I tested the TCC solenoid before by hitting it with 12v and listening for it to click. Can I check the pressure switch with air? And if so, how much?
