the wiring schematic for my pcm 16168625 doesnt show anything for e11 but i will try it out. i will hook a meter to it while i drive to see if i get any readings. what you said makes alot of sence so i hope it works im tired of manually locking my converter. i have a vacuum switch but with my cam i have trouble getting it to stay locked especially on the interstate

E10
 TCC Solenoid Transmission Terminal (T), TCC On/Off (4L60-E Only) TAN/ BLK, BRN
E11 PWM TCC Solenoid, TCC Solenoid
 Transmission TCC PWM not used in early 4L60-E (4L60-E Only), TCC On/Off (4L80-E and 700R4) BRN
Since you have a 700R4 and bin is set to manual, I beleive this is what you need to use
