Okay, so finally ditched the weak 4L60 and put in the 80. Question is I've installed the 60-80 harness so it plugs in however when it comes to the 2 other sensors in the trans all I can find is info for a truck install not our Camaros. I feel like I plug in the stock plug into the tailshafts sensor and I should be fine. But everything I can find says the other sensor should be spliced into the stock harness. HHAAALLLPPPP!!!!!

You talking about the speed sensor?

You have a rear sensor for VSS and a front for ISS. Front is not really needed if your OS doesn't need it.
