Sorry for all the questions guys but I don't know to much about these type of conversions. I discovered that the 2001 5.3 and 4L60E that I am putting in had a transmission control module. I havn't heard anybody talk about this do you need it or can you get around it and still make it work right? One more question on the 5.3 there is a little black line running by the fuel lines. Is this the vapor line? Can it be blocked off and not used? If so what is the best way to block it? I am installing it in a 84 truck. Thanks ahead of time.
