With the harness unpluggged, none of the transmission side pins should go to ground. There should be continuity from A to E, B to E, C to E and D to E. As far as pins F and G, that is a separately powered circuit and would blow a different fuse. I guess I am assuming that fuse 5C (10A) is blowing in the inst panel fuse block. If you have 3 pins going to case ground, then there is probably a wiring harness rubbed through inside the case- not a fun repair on one of those.
Here is what I found out about how to test the transmission wires.
I have not checked the tag yet. Its wet outside and I am not ready to go lay on the ground under the car to see the tag yet lol
