Trans failsafe with codes.

[GSXRliterbikz]

So I did some searching and found that there are several issues that the X trans is known for. Coming from an e38 background, I always thought the 5hp24 was a pretty rugged trans. All 740's from 97 up use them.
So I was a bit surprised to see so many possible issues.
Just wanted to check with everyone and see if some have had similar issues.

The codes I pulled were with inpa in the tcu. 5 codes. Pressure controller EDS 1-5.
All said open circuit or short circuit to ground.
Its a hard error, always present.
First time it happened was on the highway. Had been driving for over an hour, on a lightly rainy day.

From the research I did, my first place to look will be the connector on the back of the trans. I guess it can get dirty and short things out. But my issue is not intermittent. I left the car in the garage overnight and theres no change.

Other info on the car is its an 04/01 build 4.4 sport. New battery this week. Thought I might have a batt drain from something since my shifter light never shuts off. But since the new batt. I haven't had any issues with starting it. Alt light never comes on. Alt is a new one 6 months ago. Other than the new TFS, it runs great. Engine and trans temps seem normal.
