I dont know how you are connected........How is the computer going to know when to lockup the TCC, just wondering on how you are connected since the 700R4 doesn't have a VSS. 700R4 uses a gov and TV valve for upshifts. With the pin 2 mentioned, is it ground/voltage and how is it controlled. The problem with wiring to the 4th gear oil circuit in the VB is....it applies the TCC as soon as OD is applied....in town driving you will not like the results...my opinion only.

Maybe find a junkyard pull on a 4L60E....Do you have the entire wiring harness for the LS which includes the wiring harness for the transmission ?
