89 S10 Blazer 4x4 (4.3TBI - Auto)

My blazer is wanting to die when ever i goto slow or stop..This is the only time it does it..I beleve the Torque Converter is not disengaging...So, my question is..Where is the TC plug located?? so, I can unplug it and see if that fixes it..

Look on the transmission.
A 4 wire plug in.
Purple no A wire or tan/black D wire is the tcc solenoid control.
