Way easier to change on a 4L80E compared to a 4L60E, The Passthrough is easily released with a 32mm or 1 1/4" 6-point deep socket, Place the socket over the passthrough, While putting pressure on the socket....Turn it at the same time.
I have great luck with Rostra made harnesses, They use genuine Delphi connectors. 2004 & up harness are different than 2003 & down because of a EPC Solenoid change.

Alright, changing the unit sounds easy enough. My trans is from like 97, so I'm guessing the 03-down is the one.
I took all the external plugs out and looked at them. The wires and connectors all looked pretty good. The main circular plug had a little moisture in it, but didn't seem terrible and I couldn't see a leak. I packed them all with dielectric and put them back together. Fluid levels looked good warm, and fluid isn't dark or burnt smelling. Fan coolers were working so I don't think the trans ever got real hot. I drove it to another local cruise in ~20min 30-50mph. I did keep it in 3 around town out since I was curious if I could affect the trigger conditions of the code. I didn't set it off on either leg of the trip. I'll order the solenoid and keep an eye on it a bit until it arrives.
