    Just had the transmission rebulit.Have a question about a black wire? goes from the transmission to the fuse box. Someone told me that you have to replace it? Other people said you don't have to. Looking for some advise.

    There is a revised trans harness that is specifically for the '96 model years trucks with the 4L60E trans, as their was some problems with the originally designed harness... If you check with your trans shop or dealer they should know about it.
