Can anyone tell me if a 4T80E transmission harness is a two part harness as in internal and external or is it all one piece that has to be replaced.

A picture would be great too. THANKS

Down low, on the "front" side of the transmission, is a multi-pin connector. The main vehicle harness plugs in there - so, yes, there's an internal harness. Quite a few data wires, grounds, and shift controls..............

Then how do you disconnect the external part of the harness? I am sorry for the double post, my computer was acting up. Thanks

You pull the connector apart after tripping the safety latches..............perhaps I should have said ".......on the outside lower front...............".
