Well thanks for your help guys hopefully figure something out.
If you do find out what it is and where it came from be sure to come back and tell us.

Time to break out the pressure gauges I think.
Or maybe first try a full calibration of all five transmission clutch solenoid valves if you have access to ET. Apparently you can also perform the calibration using the Advisor Panel (procedure is in SIS) but I have never done it that way.

In relation to your cold tranny problem,my D9T had a similar issue a couple of years ago.Got the laptop chaps out and found a couple of cellenoids in the tranny needed replacing.Was no great problem or expense thankfully.

I'm getting transmission speed sensor fault codes. 113 585-2 and 113 673-2. Are these located inside the transmission? How do you access them? I'm thinking they might be dirty because of sporadic stalling in first gear.

They are mounted inside the transmission planetary group, and to get at them you have to pull out the transmission. You might be lucky and find it is a harness fault because they have both gone AWOL at the same time. See attached testing procedures. I'll send you an electrical schematic.

Is the transmission oil clear and bright in colour.? Doesn't smell burned at all.? If it has a good colour and no burned smell it is quite probable that your problem is electrical.

All my clutch pressures seem to be good and in operating range. I think it either has something to do with the speed sensors or the shift solenoids. Do the shift solenoids have any fault codes when they go bad?

Ok will do. I will check the oil again. Seemed like it was in pretty good condition. It just seems like it's something eletrical

20231130_075324.jpg20231130_075333.jpgI'm getting this current on #5 solenoid in first gear forward and reverse. Going to try and swap it out. Are the solenoids labeled which one is what or is there a diagram?
