4l80e swap second connector? I'm doing a 4L80E swap and got the speartech harness. I didn't even notice until after I mounted the transmission that the second connector has nothing to plug into. There is the main control connector and the 2 little ones, I'm referring to the rear small one. The front sensor plugged in but what does the rear one do?
You have two sensors on a 4l80e. The front one is a turbine speed sensor and the rear one is an output speed sensor. Good luck, Vince.

4x4 4L80E's usually have the rear connector on the transfer case, the rear hole on the trans is plugged. Thats not too bad, the problem is there is not usually a reluctor wheel for the rear sensor.
Usually you need to put the reluctor wheel on when you swap the output shaft.
