You need to figure out what application you want Use in order to get the correct info. They were used behind both the 4L60E and the 4L80E.

If your using a 4L60e/ LS type Engine thats cable driven You probally want to use like a silverado or suburban.

I can not get anyone to tell me what wires will need to stay in place, and were they will need to go so that the push button will work appropriatly. I am also finding out I may be needing a few things extra to make this work. TCCM? etc.....

Thanks for all the help in advance
